Nesse estudo descrevemos a dinâmica de cobertura da terra e de estoques e emissões brutas de carbono (C) em 55 assentamentos na Amazônia Legal, situados em 22 municípios do norte de Mato Grosso, entre julho de 2008 e julho de 2016 e discutimos suas implicações para políticas de mudanças climáticas. A estimativa de C foi baseada na mudança da cobertura da terra, obtida por processamento de imagens Spot, Sentinel e Landsat e visitas de campo, e dados secundários de valores médios de carbono por classe de vegetação. Considerando a cobertura potencial da vegetação, ou seja, a cobertura hipotética antes da ação antrópica na área, estimada pelo Instituto Brasileiro de Geografia e Estatística, os 55 assentamentos eram originalmente cobertos por 685 mil ha de vegetação nativa (103 Teragrama (Tg) de C). O desmatamento até 2016 (ocorrido antes e depois de 2008) foi superior a 65% da área de cobertura nativa. A maior parte dele (77%) ocorreu até 2008. Embora a restauração de áreas consolidadas (desmatadas antes de julho de 2008) não seja obrigatória, ela pode gerar receita com créditos de carbono, cotas de reserva ambiental, manejo florestal e agrosilvicultura. A área desmatada por assentamento até 2008 teve forte relação com a taxa de desmatamento por assentamento entre 2008 e 2016. Isso sugere que, os que desmataram muito até 2008 tendem a continuar a desmatar. A taxa de desmatamento anual entre 2008 e 2016 foi de 12,7 mil hectares (ha). Caso permaneça a mesma, toda a vegetação nativa da área terá sido suprimida em menos de duas décadas. Em geral, os assentamentos da modalidade de Projetos de Desenvolvimento Sustentável tiveram menor desmatamento, o que indica que é possível associar reforma agrária e desenvolvimento econômico e social com a conservação da floresta amazônica. Contudo, é preciso fortalecer as políticas voltadas para o pagamento de serviços ambientais e para os produtos da floresta em pé (manejo florestal de baixo impacto e de recursos não madeireiros). Para isso, é essencial a integração de esforços do governo federal, estadual, municipal e do mercado.
Ilhas de calor urbano em cidades de pequeno e médio porte no Brasil e o contexto das mudanças climáticas
Authors: Amorim Margarete Cristiane de Costa
Published: July 2020

Desde a constituição do planeta, o clima já foi mais quente e mais frio, mais úmido e mais seco do que as condições atuais. Entretanto, estamos diante de fortes alterações da paisagem natural resultantes das ações humanas, particularmente nas áreas urbanas, capazes de gerar um clima urbano específico. A expansão territorial urbana e as atividades desempenhadas pela sociedade interferem no balanço de energia devido a substituição da vegetação por construções, compactação e impermeabilização do solo, que resultam na absorção e reflexão dos diferentes materiais da superfície e também pela geração do calor antropogênico, associada às atividades humanas. As consequências de tais alterações são as ilhas de calor urbanas, que se caracterizam pelo aumento de temperatura nas cidades em relação às áreas rurais adjacentes. O objetivo deste artigo foi analisar as alterações climáticas que ocorrem na escala local, particularmente na geração de ilhas de calor, em cidades de médio e de pequeno porte localizadas no ambiente tropical continental, tendo, como exemplo analítico, episódios da estação seca. Também foram apresentadas considerações acerca da complexidade escalar em que as mudanças climáticas estão envolvidas. Para isso refletiu-se sobre a importância das cidades pequenas e médias no Brasil, pela expressão econômica e social que tomaram nos últimos anos e foram utilizados dados horários de temperatura do ar registrados com estações meteorológicas automáticas instaladas em ambientes urbanos e rurais adjacentes em Presidente Prudente (SP), Rosana (SP), Paranavaí (PR) e Nova Andradina (MS). A análise da variabilidade horária das ilhas de calor nas cidades em questão mostrou que as cidades de médio e de pequeno porte, quando não dispõem de ações efetivas de planejamento e gestão, possuem ilhas de calor de muito forte magnitude (acima de 6oC), evidenciando a gravidade dos resultados diagnosticados, apontando para a necessidade de medidas para amenizar as alterações climáticas na escala local.
Trabajadores fronterizos para el flujo mercantil global entre México y Centroamérica
Authors: Pérez Hugo Saúl Rojas
Published: July 2020

Al analizar las experiencias de los actores transfronterizos que viven y laboran entre Tecún-Umán (Guatemala) y Ciudad Hidalgo (México), se evidencia cómo ellos, a través de los servicios que ofrecen y los vínculos comerciales que generan, hacen posible un nodo mercantil a escala global —entre Norte y Centroamérica—; y de forma simultánea reproducen sus propios mecanismos locales de movilidad. El dinamismo comercial y la aglutinación de redes de distribución global que se interceptan en las ciudades transfronterizas no solo se debe a las modernas tecnologías de comunicación y transporte multimodal generadas por las necesidades de circulación del capital global, sino a la combinación de mecanismos que podríamos considerar económicamente formales con otros informales. Esta combinación de mecanismos “(in)formales” está localizada en lugares concretos y contribuye a la extracción de valor de la mano de obra local y migrante. Las narrativas de los trabajadores y los datos etnográficos esclarecen la estrecha relación entre la desigualdad social de la población local y la próspera actividad mercantil a escala global.
Malón de 1859 a Bahía Blanca: memorias conflictivas destinadas a y producidas por estudiantes de la escuela secundaria
Authors: Perrière Hernán
Published: July 2020

El presente artículo refleja el resultado de una investigación etnográfica que involucró distintas instancias educativas: en un museo de historia municipal, en los paseos didácticos organizados por la Municipalidad de Bahía Blanca hacia los museos, y en las escuelas secundarias. Lo que tienen en común estas prácticas es la referencia a un suceso histórico que se desarrolló hace 161 años en la actual ciudad de Bahía Blanca: el malón de 1859. El objetivo del artículo es indagar sobre los procesos de memorias y de producción de conocimientos en torno a este hecho y en los contextos en los cuales se producen. Las tres instancias seleccionadas tienen en común el desarrollo de narraciones o relatos destinados a un público juvenil que transita la escuela secundaria. La hipótesis que sostengo es que en dichos discursos, si bien predominan las narrativas hegemónicas vinculadas a la constitución del Estado nación y, por lo tanto, justificadoras del genocidio indígena, estas están siendo cuestionadas en las escuelas secundarias desde una perspectiva intercultural.
Le Bassin minier du Nord-Pas-de-Calais, un patrimoine évolutif et vivant. Entre conservation et évolution, enjeux et nouveau paradigme pour les projets d’architecture
Authors: Prost Philippe , Monsaingeon Lucas
Published: July 2020

Le bassin minier du Nord et du Pas-de-Calais se caractérise par un paysage, un urbanisme et une architecture résultants de deux siècles d’exploitation intensive du charbon, en transition brutale suite à l’arrêt des mines de 1960 à 1990. Avec son inscription en 2012 sur la liste du patrimoine mondial au titre de « paysage culturel évolutif et vivant », la reconnaissance de ce territoire, pensée comme une force de résilience pour une transition ambitieuse, a porté la question patrimoniale et architecturale - avec plus de 28 000 logements inscrits - sur un terrain rarement abordé et à une échelle inédite, soulevant de nombreuses questions tant pour les architectes que pour les urbanistes et paysagistes. Nous reviendrons dans un premier temps sur les enjeux de cette reconnaissance patrimoniale quant aux projets d’architecture sur l’existant, puis nous présenterons dans un second temps le contexte et la méthode de la recherche-action menée pour le compte de la Mission Bassin Minier entre 2017 et 2019 par l’Atelier d’Architecture Philippe Prost. Enfin, dans un dernier temps nous détaillerons les résultats opérationnels de ces travaux destinés à poser les bases d’un référentiel partagé pour intervenir sur le patrimoine minier, entre préservation et évolution.
La Patrimonialisation de l’héritage minier dans le Nord-Pas-de-Calais : un outil efficace de réconciliation de la population locale avec son passé ?
Authors: Mortelette Camille
Published: July 2020

En 2012, le Bassin minier du Nord-Pas-de-Calais devient patrimoine mondial de l’Unesco au titre de « paysage culturel évolutif vivant ». Cette inscription est présentée comme le point d’orgue d’un processus de patrimonialisation commencé dans les années 1990. Les discours des acteurs patrimoniaux évoquent régulièrement la possibilité d’un « retour de la fierté » pour les habitants du territoire grâce à cette inscription. En effet, tout comme le Louvre Lens, elle est associée à une reconnaissance des institutions pour la population locale et elle a pour but de faire œuvre de réconciliation entre la population et un patrimoine qui a pendant longtemps été déconsidéré. Cependant, cette inscription Unesco n’a-t-elle que des effets entièrement positifs pour ces habitants ? À partir de travaux de thèse achevés en 2019, le présent article s’attache à démontrer que malgré des dispositifs volontiers décrits comme favorisant la participation habitante, le processus patrimonial engagé est encore essentiellement institutionnel et descendant. Il met également en avant que, malgré une inscription valorisée par la majorité des habitants, celle-ci est également porteuse de contraintes dans leurs pratiques spatiales quotidiennes et d’ambigüités dans le renouvellement des représentations territoriales qu’elle propose.
Le bassin minier du Nord-Pas-De-Calais pris dans les rets de l’aménagisme généralisé
Authors: Céleste Patrick
Published: July 2020

Le bassin minier du Nord-Pas-de-Calais ne peut être séparé du contexte plus large dans lequel il s’inscrit. A-t-il d’ailleurs un jour existé sinon aux lendemains de la Seconde Guerre mondiale, quand les différentes concessions minières du Nord et du Pas-de-Calais furent regroupées en une seule main nationale (Les Charbonnages de France) qui ne fut dissoute qu’en 2007 ? Le territoire du bassin minier relève d’une construction et n’a trouvé pleinement son statut qu’avec sa reconnaissance par l’Unesco, en 2012, comme patrimoine mondial de l’humanité, soit plus de deux décennies après la fermeture du dernier puits. « Réparer les territoires post-miniers » ne peut alors se concevoir et être efficace que si cette réparation se fait en étroite interaction entre les différentes échelles du territoire. C’est ce à quoi s’attachera cet article en montrant comment « réparer » peut se comprendre de plusieurs manières : comme conservation d’un patrimoine, en assurant sa mémoire et sa pérennité, comme ouverture à de nouveaux usages et enfin comme nécessité consécutive à de profonds traumatismes, ceux que l’exploitation minière a fait subir aux personnes et au territoire. Au-delà des seuls mineurs, c’est l’ensemble des habitants du département qui continue d’en subir les conséquences. S’y ajoutent d’autres processus destructeurs d’ampleur comparable aux deux précédents : le « tout voiture » et l’étalement urbain. Deux domaines de réparation se conjuguent donc : ceux propres au bassin minier et ceux propres aux formes contemporaines de l’occupation du territoire. C’est en tant qu’architecte-conseil de l’État ayant travaillé sur des dossiers relevant du bassin minier que je souhaite porter témoignage. Je me suis forgé une conviction que je livre dans ces pages : réparer le bassin minier doit se faire en contribuant à une réparation à l’échelle du territoire en améliorant ses différentes entités géographiques, économiques, matérielles et sociales, en acceptant toutefois la fonction stimulante de la dysharmonie généralisée à laquelle ont mené tant de décennies d’aménagisme. Il nous faut donc reconnaître et travailler à l’évolution des paysages, donc de l’aménagement, à partir de cette acceptation. Elle n’est pas pour autant, loin s’en faut, un renoncement.
The Leftovers, the Lost fever
Authors: Dulong Guillaume
Published: July 2020

Cet article analyse le dernier épisode de The Leftovers, « The Book of Nora » (S03E08), en son opposition avec l’épisode « The Book of Kevin » (S03E01) comme légendes interprétatives concurrentes de la série en se focalisant sur le thème du bouc émissaire et son traitement audiovisuel ramené à la persona spéciale de Nora (Carrie Coon). Ce faisant, nous nous demandons ce que signifie l’accusation proférée à l’encontre de celle-ci dans l’épisode « Lens » (S02E06) d’être Azraël et en quoi The Leftovers est apocalyptique. Il ne s’agit pas uniquement de désigner ce personnage responsable de l’incident par lequel s’origine l’histoire, elle est celle qui répond de la vraie version du récit mais aussi nous dévoile notre regard accusateur sur ce dernier. Ainsi en télescopant les définitions de la profanation parodique de Giorgio Agamben et les études de René Girard sur le phénomène socioculturel de bouc émissaire, prétendons-nous dégager la montée aux extrêmes des tensions, la double frénésie traversant The Leftovers intérieurement, mais aussi dans son rapport à la série précédente de Damon Lindelof, Lost. Peut-on espérer le retour de l’Île de Lost dans The Leftovers ?
Le human beatbox entre musique et parole : quelques indices acoustiques et physiologiques

Published: July 2020

Technique vocale impliquant l’appareil vocal pour imiter des instruments de musique ou des sons électroniques, le human beatbox est décrit acoustiquement et physiologiquement. Musicalement parlant, entre les trompettes bouchées, grosses caisses, charleston et caisses claires originales et imitées, les oscillogrammes, courbes mélodiques, spectrogrammes et pentes spectrales montrent plusieurs ressemblances. En outre, la notation des percussions utilisées par les beatboxeurs rend compte d’analogies entre celles-ci et certaines consonnes des langues du monde, analogies quantifiables par exemple par une intensité plus faible et une énergie plus concentrée dans le grave pour la grosse caisse que pour la caisse claire beatboxées, comme [p] et [t] respectivement. Nos analyses aérodynamiques ont montré que la production de percussions beatboxées s’apparentait à celle de consonnes éjectives pour la grosse caisse beatboxée (notamment fermeture des plis vocaux juste avant l’explosion), implosives pour la caisse claire (notamment flux d’air inhalé avant le bruit d’explosion), et de clics pour la charleston beatboxée (notamment débit d’air nasal décroissant puis croissant). Le larynx est sollicité comme vibrateur et articulateur ; ses composants sont utilisés de manière indépendante. Les lèvres et la langue participent également à la production de ces sons beatboxés, ainsi situés entre musique et parole.
Anaesthesia in a child with uncorrected aortopulmonary window for non-cardiac surgery
Authors: Kulkarni Malavika , Sushma T. K. , Shastry Avinash
Published: July 2020

Aortopulmonary window (APW) is a rare congenital cardiac anomaly characterized by communication between ascending aorta and main pulmonary artery. It represents between 0.2% and 0.3% of all congenital cardiac lesions. The anaesthetic management of a child with severe pulmonary hypertension associated with right to left shunt is clearly a demanding situation.A 13 year old boy presented for open reduction and internal fixation of right femur. The child was diagnosed with congenital heart disease, APW with severe irreversible Pulmonary Artery Hypertension (PAH). Anaesthetic management comprised of a balanced approach with administration of general anaesthesia and regional analgesia with perioperative invasive haemodynamic monitoring.
Delayed recovery from general anaesthesia following thyroidectomy: a "near miss"
Authors: Gunasekera Dassanayake Vihara Erangika , Welikala Nadeeshya Dulanjalee , Ramasinghe Sachintha Lakmal
Published: July 2020

Thyroid storm is an endocrine emergency which carries a high mortality. The spectrum of emergencies can vary from an impending storm to a thyroid crisis depending upon the degree of systemic decompensation. It is a clinical diagnosis which can be supported by biochemical investigations. In the perioperative setting a multitude of factors can act as potential triggers for a patient to develop a thyroid storm. However subtle signs of an “impending storm” can be masked by other co-morbid factors which befits the phrase “calm before a storm”. There are a number of case reports in the literature on delayed recovery in hypothyroid patients undergoing general anaesthesia for various procedures. However, there were no reported cases of delayed recovery among patients with hyperthyroidism following surgery secondary to an impending storm. We report a case of a 48- year old man who underwent a total thyroidectomy combined with a herniorrhaphy and a hydrocelectomy and had a delayed recovery from general anaesthesia due to an impending thyroid storm, which could have resulted in a catastrophic postoperative period.

Intercultural Experiences Prior to the Educational Program: Occupational Therapy and Social Work Students
Authors: Tétreault Sylvie , Bétrisey Carine , Brisset Camille , Gulfi Alida , Schaer Martine , Leanza Yvan , Kühne Nicolas
Published: July 2020

In the health and social professions, including occupational therapy and social work, interactions and exchanges with people are essential. Populations encountered by professionals in these fields are becoming increasingly diverse in terms of age, origin, language, health status, and socio-economic background. Sometimes, professionals can have potential misinterpretations regarding intentions and actions, health beliefs and practices, or verbal and non-verbal communication. To overcome obstacles related to practice in a context of diversity, universities must develop students’ intercultural competence. Scientific literature stresses the importance of encountering diversity to improve awareness and sensitivity and to bring attention to biases and prejudices. Considering students’ intercultural experiences before their formation could be a basis to achieve this educational goal. The present study aims to document this topic. Semi-structured interviews with 51 first-year students from two educational institutions in French-speaking Switzerland were conducted to capture the participants’ descriptions of these experiences in private or professional contexts. The interviews were transcribed and submitted to a thematic analysis approach. A thematic map was generated and three main themes emerged: (1) perception of diversity; (2) communication challenges; and (3) transformation of attitudes toward the “Other.” They are described and discussed in terms of developing intercultural competence. Recommendations regarding intercultural education emerge from these findings.
Najvažnije parazitarne zoonoze i njihovo javno-zdravstveno značenje u zemljama Europe
Authors: Balić Davor , Škrivanko Mario
Published: July 2020

Godišnje radionice Europskog referentnog laboratorija za parazite (EURLP) smještenog u Višem institutu za zdravlje (Istituto Superiore di Sanita) u Rimu, prilika su za upoznavanje s aktualnim stanjem najvažnijih parazitarnih zoonoza u Europi. Tijekom dvodnevne radionice predstavnici nacionalnih referentnih laboratorija (NRL) usmeno ili posterima izvještavali su o epidemiološkim i epizootiološkim osobitostima parazitarnih zoonoza u njihovim zemljama tijekom protekle godine. Prezentirani podatci uglavnom se odnose na: godišnje preglede registriranih slučajeva oboljelih ljudi, izvore invadiranja, načine širenja i prenošenja invazija, ispitivanja kojima se provjerava prisutnost, otpornost i preživljavanje razvojnih stadija parazita u okolišu kao i na opise neuobičajenih pojava rijetkih invazivnih zoonoza zabilježenih u europskim zemljama. Epizootiološki podatci odnose se na istraživanja, tj. nadzor nad prisutnošću pojedinih vrsta parazita i/ili njihovih razvojnih stadija u domaćim i divljim životinjama te njihovom potencijalnom značenju za zdravlje ljudi. Sumirane podatke i trendove koji se uoče obradom podataka na razini cijele EU prezentiraju predstavnici Europske agencije za sigurnost hrane (EFSA) i Opće uprave za zdravlje i zaštitu potrošača EU (DG SANCO). Osim predstavnika zemalja članica EU na radionicama su prisutni i predstavnici nečlanica EU, poput Islanda, Norveške, Švicarske, Sjeverne Makedonije i Srbije, koji su često uključeni u zajedničke projekte s članicama zemalja EU i/ili žele biti informirani o aktualnostima iz područja parazitarnih zoonoza na području EU. Posebna pozornost pridaje se predavanjima pozvanih parazitologa iz Europe i svijeta koji prezentiraju rezultate i otkrića dugogodišnjeg rada svojih timova o pojedinim parazitozama i njihovom značenju za javno zdravstvo. Cilj je ovoga rada bio informirati o ehinokokozi i trihinelozi kao najvažnijim parazitozama za javno zdravstvo EU te izvijestiti o značenju i osobitostima opistorhioze koja je opširnije prezentirana na godišnjoj radionici održanoj 2018. godine. Izvijestli smo o neočekivano velikom broju oboljelih ljudi od trihineloze u Hrvatskoj koji je registriran 2017. godine u nekoliko epidemija i sporadičnih slučajeva. Najveća epidemija dogodila se nakon konzumiranja mesnih proizvoda napravljenih od mesa divlje svinje što je i prva službena potvrda invadiranja mesom druge vrste, osim domaće svinje, na području Hrvatske. Zbog karakteristične epidemiološke situacije trihineloza u Hrvatskoj i dalje ostaje parazitoza od najvišeg javno-zdravstvenog značenja.
Synthesis of Natural Food Colour from Carotenoid using Flower Petals
Authors: Naganandhini K , Palaniswamyi, Radha
Published: July 2020

Colour is an important characteristic of food. Since the colours are obtained from synthetic origin, it shows
some adverse effect to humans. So it is an alternative way to use natural food colour obtained in the form a
carotenoid pigments along with health benefits, In this current study, natural food colours are obtained by
means of a carotenoid pigments by using flower petals of Hibiscus rosa- sinesis, senna auriculata, Magnolia
champaca and Ixora coccinea by using the solvent extraction method. During the extraction upper phase
containing carotenoid pigments are separated. The extracted pigments are then subjected to confirmatory
assessment of carotenoid pigments by UV spectrophotometer. Phytochemical analysis was done to each
extract to see the bio active compound present in it. Extracted sample was studied for antioxidant activity,
antibacterial activity for each extract was performed against Escherichia coli. To identify the mixture of
compounds, it was subjected to Thin Layer Chromatography, then analysed and compared with the
standard carotenoid. To identify molecular components and structure of the each extract and functional
group present in it, FTIR was done. Each sample of extraction was checked for the physical parameters like
stability and pH. The obtained natural carotenoid colour pigments were incorporated in food along
phytochemical properties too.

Published: July 2020

Diperlukan adanya suatu kepastian hukum yang diwujudkan dalam suatu alat bukti yang kuat yaitu berupa akta autentik dalam perbuatan hukum (jual beli, kontrak, sewa meyewa dan lainnya) maka kedudukan dan wewenang notaris sebagai Pejabat Umum yang satu-satunya berwenang dalam pembuatan akta autentik (kecuali ditentukan lain oleh Undang-Undang) juga semakin penting. Tujuan pengabdian ini adalah untuk mensosialisasikan pentingnya akta autentik dimana salah satu perbuatan hukum yang penting dibuat dengan akta autentik yaitu jual beli hak atas tanah yang dibuat oleh Notaris. Adapun yang menjadi mitra pengabdian yaitu kantor kecamatan Medan Johor. Metode pengabdian dilakukan dengan cara branstorming, presentasi dan diskusi, simulasi yang didukung dengan media slide. Kemudian dilakukan sesi tanya jawab kepada para peserta. Hasil pengabdian bahwa masyarakat kecamatan Medan Johor belum seluruhnya memahami tentang pentingnya akta autentik, terutama dalam melakukan jual beli hak atas tanah. Peralihan hak atas tanah yang belum bersertipikat masih terdapat ketidakseragaman yang dilakukan sebagian masyarakat di Kecamatan Medan Johor, ada yang bertransaksi hanya dengan menggunakan bukti kwitansi saja, ada yang melaksanakan transaksi dan membuat surat pelepasan haknya di kantor Lurah, ada yang di kantor Camat dan ada juga yang melaksanakannya di Kantor Notaris. Hal ini disebabkan beberapa faktor yaitu ketidaktahuan, kebiasaan, biaya dan kurangnya sosialisasi dari pemerintah mengenai ketidakseragaman bentuk perolehan haknya. Kata kunci : Akta Autentik, Notaris, Jual Beli

Heidegger e a ilusão transcendental
Authors: Ramos dos Reis Róbson
Published: July 2020

Este artigo apresenta uma análise da abordagem de Heidegger à dialética transcendental no contexto de sua interpretação da Crítica da Razão Pura de Kant. Inicialmente, reconstruo a interpretação fenomenológica da Crítica da Razão Pura como sendo uma fundamentação da metafísica. A seguir, apresento a compreensão de Heidegger sobre o que ele chamou de significado positivo da dialética transcendental. O foco principal de sua interpretação é a noção de ilusão transcendental. Concluo este artigo examinando a noção de uma ilusão original, que Heidegger concebe como mais básica do que a ilusão transcendental examinada por Kant. Enfatizo que as subreções transcendentais que Kant explicou na dialética transcendental são interpretadas por Heidegger como casos particulares de uma confusão mais geral, cuja origem pertence à própria estrutura da compreensão do ser.

Abstract. The current inadequate understanding of ice nucleating particle (INP) sources in the Arctic region affects the uncertainty in global radiative budgets and in regional climate predictions. In this study, we present atmospheric INP concentrations by offline analyses on samples collected at ground level in Ny-Ålesund (Svalbard), in spring and summer 2018. The ice nucleation properties of the samples were characterized by means of two offline instruments: the Dynamic Filter Processing Chamber (DFPC), detecting condensation freezing INPs, and the West Texas Cryogenic Refrigerator Applied to Freezing Test system (WT-CRAFT), measuring INPs by immersion freezing. Both measurements agreed within an order of magnitude although with some notable offset. INP concentration measured by DFPC ranged 33–185 (median 88), 5–107 (50) and 3–66 (20) m−3, for T = −22, −18 and −15 °C, respectively, while at the same activation temperatures WT-CRAFT measured 3–199 (26), 1–34 (6) and 1–4 (2) m−3, with an offset apparently dependent on the INP activation temperature. This observation may indicate a different sensitivity of Arctic INPs to different ice nucleation modes, even though a contribution from measurement and/or sampling uncertainties cannot be ruled out. An increase in the coarse INP fraction was observed from spring to summer, particularly at the warmest temperature (up to ~ 70 % at −15 °C). This suggests a non-negligible contribution from local sources of biogenic aerosol particles. This conclusion is also supported by the INP temperature spectra, showing ice-forming activity at temperatures higher than −15 °C. Contrary to recent works (e.g., INP measurements from Ny-Ålesund in 2012), our results do not show a sharp spring-to-summer increase of the INP concentration, with distinct behaviors for particles active in different temperature ranges. This likely indicates that the inter-annual variability of conditions affecting the INP emission by local sources may be wider than previously considered and suggests a complex interplay between INP sources. This demonstrate the necessity of further data coverage. Analysis of INP concentrations, active site density, low-travelling back-trajectories (

Abstract. Clouds play a potentially important role in Arctic climate change, but are poorly represented in current atmospheric models across scales. To improve the representation of Arctic clouds in models, it is necessary to compare models to observations to consequently reduce this uncertainty. This study compares aircraft observations from the Arctic Cloud Observations Using Airborne Measurements during Polar Day (ACLOUD) campaign in May/June 2017 around Svalbard, Norway – to simulations using the ICON (ICOsahedral Non-hydrostatic) model in its numerical weather prediction (NWP) set-up at 1.2 km resolution. By comparing measurements of solar and terrestrial irradiances during ACLOUD flights to the respective properties in ICON, we showed that the model systematically overestimates the transmissivity of the mostly liquid clouds during the campaign. This model bias is traced back to the way cloud condensation nuclei (CCN) get activated into cloud droplets in the two-moment, bulk microphysical scheme used in this study. This process is parameterized as function of grid-scale vertical velocity in the microphysical scheme used, but in-cloud turbulence cannot sufficiently be resolved at 1.2 km horizontal resolution in Arctic clouds. By parameterizing subgrid-scale vertical motion as a function of turbulent kinetic energy, we are able to achieve a more realistic CCN activation into cloud droplets. Additionally, we showed that by scaling the presently used CCN activation profile, the hydrometeor number concentration could be modified to be in better agreement with ACLOUD observations in our revised CCN activation parameterization. This consequently results in an improved representation of cloud optical properties in our ICON simulations.

Abstract. Ozone (O3) plays a significant role in weather and climate on regional to global spatial scales. Most studies on the variability in the total column of O3 (TCO) are typically analysed using daytime data. Based on knowledge of the chemistry and transport of O3, significant deviations between daytime and nighttime O3 are only expected either in the planetary boundary layer (PBL) or high in the stratosphere or mesosphere, having little effect on the TCO. Hence, we expect the daytime and nighttime TCO to be very similar. Comparing daytime and nighttime TCOs thus provides an approach to verify the retrieval algorithms of infrared instruments like the Atmospheric InfraRed Sounder (AIRS) and the Microwave Limb Sounder (MLS). Applying this verification on the AIRS and the MLS data we identified inconsistencies in observations of O3 from both satellite instruments. For AIRS, daytime-nighttime differences were found over oceans resembling cloud cover patterns, and over land, mostly over dry land areas, likely related to infrared surface emissivity. These differences point to issues with the representation of both processes in the AIRS retrieval algorithm. For MLS, a major issue was identified with the “ascending-descending” orbit flag, used to discriminate nighttime and daytime MLS measurements. Disregarding this issue, MLS day-night differences were significantly smaller than AIRS day-night differences, providing additional support for retrieval method origin of AIRS day-night TCO differences. MLS day-night differences are dominated by the upper stratospheric and mesospheric diurnal O3 cycle. These results provide useful information for improving infrared O3 products and at the same time will allow study the day-night differences of stratospheric and mesospheric O3.

Abstract. In the western Mediterranean Sea, Levantine intermediate
waters (LIW), which circulate below the surface productive zone,
progressively accumulate nutrients along their pathway from the Tyrrhenian
Sea to the Algerian Basin. This study addresses the role played by diffusion
in the nutrient enrichment of the LIW, a process particularly relevant
inside step-layer structures extending down to deep waters – structures known as thermohaline
staircases. Profiling float observations confirmed that staircases develop
over epicentral regions confined in large-scale circulation features and
maintained by saltier LIW inflows on the periphery. Thanks to a high
profiling frequency over the 4-year period 2013–2017, float observations
reveal the temporal continuity of the layering patterns encountered during
the cruise PEACETIME and document the evolution of layer properties by
about +0.06 ∘C in temperature and +0.02 in salinity. In the
Algerian Basin, the analysis of in situ lateral density ratios untangled double-diffusive convection as a driver of thermohaline changes inside epicentral regions and isopycnal diffusion as a driver of heat and salt
exchanges with the surrounding sources. In the Tyrrhenian Sea, the nitrate
flux across thermohaline staircases, as opposed to the downward salt flux,
contributes up to 25 % of the total nitrate pool supplied to the LIW by
vertical transfer. Overall, however, the nutrient enrichment of the LIW is
driven mostly by other sources, coastal or atmospheric, as well as by inputs
advected from the Algerian Basin.

Abstract. Late Quaternary volcanic basins are active landscapes from which detailed archives of past climate and seismic and volcanic activity can be obtained. A multidisciplinary study performed on a transect of sediment cores was used to reconstruct the depositional evolution of the high-elevation Laguna del Maule (LdM) (36∘ S, 2180 m a.s.l., Chilean Andes). The recovered 5 m composite sediment sequence includes two thick turbidite units (LT1 and LT2) and numerous tephra layers (23 ash and 6 lapilli). We produced an age model based on nine new 14C AMS dates, existing 210Pb and 137Cs data, and the Quizapú ash horizon (1932 CE). According to this age model, the relatively drier Early Holocene was followed by a phase of increased productivity during the mid-Holocene and higher lake levels after 4.0 ka cal BP. Major hydroclimate transitions occurred at ca. 11, 8.0, 4.0 and 0.5 ka cal BP. Decreased summer insolation and winter precipitation due to a southward shift in the southern westerly winds and a strengthened Pacific Subtropical High could explain Early Holocene lower lake levels. Increased biological productivity during the mid-Holocene (∼8.0 to 6.0 ka cal BP) is coeval with a warm–dry phase described for much of southern South America. Periods of higher lake productivity are synchronous to a higher frequency of volcanic events. During the Late Holocene, the tephra layers show compositional changes suggesting a transition from silica-rich to silica-poor magmas at around 4.0 ka cal BP. This transition was synchronous with increased variability of sedimentary facies and geochemical proxies, indicating higher lake levels and increased moisture at LdM after 4.0 ka cal BP, most likely caused by the inception of current El Niño–Southern Oscillation and Pacific Decadal Oscillation (ENSO–PDO) dynamics in central Chile.
Technical note: A prototype transparent-middle-layer data management and analysis infrastructure for cosmogenic-nuclide exposure dating
Authors: Balco Greg
Published: July 2020

Abstract. Geologic dating methods for the most part do not directly measure ages. Instead, interpreting a geochemical observation as a geologically useful parameter – an age or a rate – requires an interpretive middle layer of calculations and supporting data sets. These are the subject of active research and evolve rapidly, so any synoptic analysis requires repeated recalculation of large numbers of ages from a growing data set of raw observations, using a constantly improving calculation method. Many important applications of geochronology involve regional or global analyses of large and growing data sets, so this characteristic is an obstacle to progress in these applications. This paper describes the ICE-D (Informal Cosmogenic-Nuclide Exposure-age Database) database project, a prototype computational infrastructure for dealing with this obstacle in one geochronological application – cosmogenic-nuclide exposure dating – that aims to enable visualization or analysis of diverse data sets by making middle-layer calculations dynamic and transparent to the user. An important aspect of this concept is that it is designed as a forward-looking research tool rather than a backward-looking archive: only observational data (which do not become obsolete) are stored, and derived data (which become obsolete as soon as the middle-layer calculations are improved) are not stored but instead calculated dynamically at the time data are needed by an analysis application. This minimizes “lock-in” effects associated with archiving derived results subject to rapid obsolescence and allows assimilation of both new observational data and improvements to middle-layer calculations without creating additional overhead at the level of the analysis application.

Abstract. Model-calculated forecasts of soil organic carbon (SOC) are important for approximating global terrestrial carbon pools and assessing their change. However, the lack of detailed observations limits the reliability and applicability of these SOC projections. Here, we studied if state data assimilation (SDA) can be used to continuously update the modeled state with available total carbon measurements in order to improve future SOC estimations. We chose six fallow test sites with measurements time series spanning 30 to 80 years for this initial test. In all cases, SDA improved future projections but to varying degrees. Furthermore, already including the first few measurements impacted the state enough to reduce the error in decades long projections in by at least 1 t C ha−1. Our results show the benefits of implementing SDA methods for forecasting SOC, but also highlight implementation aspects that need consideration and further research.

Published: July 2020

Abstract. The Radiative Transfer Model (RTM) is an explicitly resolved three-dimensional multi-reflection radiation model integrated in the PALM modelling system. It is responsible for modelling of complex radiative interactions within the urban canopy and it represents a key component of modelling of energy processes inside the urban layer, and consequently PALM's ability to provide explicit simulations of urban canopy in meter-scale resolution. This paper describes RTM version 3.0 which is integrated in PALM modelling system version 6.0. This version of RTM has been substantially improved over previous versions with new simulated processes, providing a more realistic representation of a wider range of urban scenarios, as well as with new discretization schemes and algorithms for a significantly better scalability and computational efficiency, enabling larger parallel simulations with up to many thousands of parallel processes.
