HISTORICAL AND PEDAGOGICAL DIALECTICS OF THE DEVELOPMENT OF ERSON LIFE-CREATION’S THEORY AND PRACTICE IN NATIONAL EDUCATION IN THE 16TH AND EARLY 20TH CENTURY
Authors: Mavrin Vitalii
Published: March 2021

The article analyzes socio-political, cultural and educational prerequisites for the development of life-creation pedagogy at the Cossack times and during the times when Ukrainian lands were under the Russian and Austrian empires. It was found out in the study that the development of life-creation pedagogy at the Cossack times was facilitated by the following factors: personal liberty and dignity as social practice, emergence of a new educational phenomenon of Cossack pedagogy, which envisaged the development of a person as a creator of own life. During the period, when Ukrainian lands were ruled by the Russian and Austrian empires the development of life-creation pedagogy was complicated by enslavement and constant pressure on national culture for the purpose of its destruction. The study defined the contribution of such Ukrainian teachers as Hryhoriy Skovoroda, Pamfil Yurkevych, Mykola Korf, Ivan Franko, Borys Grinchenko to the development of conceptual framework of life-creation pedagogy.
The scientific novelty of the obtained results is the following: for the first time a holistic historical and pedagogical analysis of the Ukrainian life-creation pedagogy theory and practice was conducted; the socio-political, cultural and educational prerequisites for the development of Ukrainian life-creation pedagogy from the Cossack times were comprehensively reviewed. The research specifies the following: the content of the life-creation concept, taking into account the procedural and practical, creative and acmeological, life-creation phenomenon evaluative and semantic aspects; the scientific argumentation concerning the theoretical structuring of life-creation pedagogy as an educational concept; the methodological approaches and principles for the correct interpretation of life-creation pedagogy conceptual ideas in historical and pedagogical context; the social, methodological and pedagogical criteria for the Ukrainian life-creation pedagogy theory and practice development periodization.

O Programa de Educação pelo Trabalho para a Saúde (PET-Saúde) é uma estratégia que preconiza ações para reconstrução da formação profissional e qualificação dos profissionais da saúde, mediante a integração ensino, serviço e comunidade. À sombra desse olhar, o presente trabalho visa descrever, através de estudo exploratório com abordagem qualitativa, a relevância da interprofissionalidade para o cuidado das pessoas com diabetes e hipertensão, com base nas experiências dos participantes da Universidade Federal de Catalão (UFCAT) que foram propiciadas pelo PET-Saúde. As ações desenvolvidas fortalecem e articulam o ensino, a pesquisa, a extensão e a participação social, garantindo uma melhora significativa dos serviços de saúde, através da troca constante de vivências nos ambientes de atuação e da consolidação das possibilidades de cuidado integral com a proposta de garantir uma visão das necessidades globais do indivíduo, família e comunidade, assim como suscita um novo olhar para a conformação dos saberes e práticas cotidianas. O processo é norteado pela diretriz da universalidade de acesso aos serviços de saúde e amparado na assimilação da postura crítica e reflexiva dos usuários do SUS e dos mediadores do cuidado. Espera-se, portanto, que a interprofissionalidade contribua para a ampliação da resolutividade da Atenção à Saúde, de modo a trazer maior articulação de ações e serviços na Rede de Atenção à Saúde (RAS). Práticas como essas devem ser encorajadas, na tentativa de contribuir para uma formação com abordagem ampliada à luz da Educação Interprofissional (EIP) e de tornar os fazeres em saúde condicionados ao cuidado adequado às necessidades de saúde da população.
GLIOMAS, TUMORES MALIGNOS QUE SURGEM NO SISTEMA NERVOSO
Authors: Santos André Luiz dos
Published: March 2021

Gliomas são os tumores cerebrais primários mais frequentes, representando mais de 70% de todas as neoplasias do Sistema Nervoso Central. Tanto o diagnóstico como a classificação destes tumores são baseados nas características histopatológicas que, por vezes, são difíceis de definir. Apesar dos avanços na neurocirurgia, quimioterapia e radioterapia, o prognóstico dos doentes com gliomas continua muito reservado. Nas últimas duas décadas, o tratamento para os gliomas de alto grau envolveu uma abordagem multidisciplinar, que se baseava em resseção cirúrgica máxima, quando possível, seguida de radioterapia e quimioterapia. Esta constitui a abordagem terapêutica convencional, com um grande número de ensaios clínicos que revelaram na sua maioria pequenas melhorias que não são satisfatórias. Sendo assim, este estudo tem como objetivo realizar uma revisão bibliográfica para coletar informações sobre o glioma, assim como, os avanços nos diagnósticos e tratamentos. Na atualidade as opções terapêuticas disponíveis no tratamento de gliomas, (que incluem, em linhas gerais, cirurgia, RT e QT), ainda não são suficientemente eficazes no controle da progressão da doença. Estudos experimentais demonstraram que a combinação de terapia antiangiogênica, baseada na ruptura de vasos sanguíneos tumorais, com quimioterapia convencional gera resultados encorajadores.
AFETIVIDADE E APRENDIZAGEM — PERCEPÇÕES DO PROFESSOR NO ENSINO FUNDAMENTAL I
Authors: Oliveira Maria Luiza Sobreira de
Published: March 2021

A presente pesquisa é resultado da reflexão sobre como os professores alfabetizadores percebem a afetividade na sua prática, a importância e relação que estabelecem entre afetividade e aprendizagem. O público-alvo foi um grupo de 15 professores de três escolas de um município da Grande São Paulo. Considera-se a partir das análises que os professores percebem a afetividade como essencial, no processo de alfabetização, tanto que, pontuaram que deveria ser considerada a partir da escolha da classe. O professor acredita que a afetividade se relaciona com a cognição e que essa relação se dá por meio do vínculo nas relações: professor-aluno; aluno-aluno, aluno-conhecimento, e pela motivação. A importância apontada para a afetividade, na prática, mais uma vez se relaciona à motivação que impulsiona o aluno durante o processo de aprendizagem. Os relatos nas entrevistas, demonstram nas diversas situações que, quando se há respeito, compreensão, diálogo e principalmente quando os aspectos afetivos e cognitivos do sujeito são considerados no processo de aprendizagem, a alfabetização acontece de forma satisfatória, no entanto, nos chama atenção  alguns professores apontarem para a afetividade como importante para manter a sala de aula disciplinada, esse dado nos leva a refletir que em muitas situações o professor pode utilizar a afetividade como meio de controle de seus alunos e não como favorecedora da aprendizagem.

Published: March 2021

A palavra estresse vem do inglês stress, tendo sido usado inicialmente na física para traduzir o grau de deformidade sofrido por um material quando submetido a um esforço ou tensão, sendo mais tarde transposto para a medicina e biologia, com a significação de esforço e adaptação do organismo para enfrentar situações que considere ameaçadoras a sua vida e a seu equilíbrio interno, e seu enfrentamento com a religião faz parte do comportamento do indivíduo, criando um interesse da Psicologia no seu estudo. Este trabalho buscou identificar as estratégias de enfrentamento religioso/espiritual entre 35 alunos de psicologia numa abordagem quantitativa através da Escala de Atitude Religiosa, Escala de Coping Religioso-Espiritual e o Inventário de Sintomas de Stress para Adultos de Lipp. Foi encontrada uma influência visível da religião sobre o comportamento e modo de pensar dos alunos, com estratégias de coping mais usadas relacionadas ao comportamento proativo do sujeito. Na amostra estudada, os alunos menos estressados recorriam a estratégias de enfrentamento religioso/espiritual, ressaltando a característica protetiva dessa forma de coping.

Published: March 2021

Ceonozoic deep-sea sediment archives from the southwest Pacific have been used to reconstruct regional climatic and environmental changes associated with global warming events from the earliest Eocene to the Last Interglacial. Less attention has been given to the biotic significance of associated changes in microfossil assemblages. Here we report what is currently known of the effects that global warming events have had on regional plankton communities, specifically foraminifera, calcareous nannoplankton, radiolarians and dinoflagellates. We focus on a succession of events representative of different magnitudes of global warming, including the Paleocene-Eocene thermal maximum, early and middle Eocene climatic optima, middle Miocene climatic optimum, mid-Pliocene warm period, and the Last Interglacial. From this study, we hope to establish ways in which the fossil record can be applied to assess the resilience of modern marine plankton communities to current and future global warming.

Published: March 2021

The core tools of science (data, software, and computers) are undergoing a rapid and historic evolution, changing what questions scientists ask and how they find answers. Earth science data are being transformed into new formats optimized for cloud storage that enable rapid analysis of multi-petabyte datasets. Datasets are moving from archive centers to vast cloud data storage, adjacent to massive server farms. Open source cloud-based data science platforms, accessed through a web-browser window, are enabling advanced, collaborative, interdisciplinary science to be performed wherever scientists can connect to the internet. Specialized software and hardware for machine learning and artificial intelligence (AI/ML) are being integrated into data science platforms, making them more accessible to average scientists. Increasing amounts of data and computational power in the cloud are unlocking new approaches for data-driven discovery. For the first time, it is truly feasible for scientists to bring their analysis to the data without specialized cloud computing knowledge. Practically, for scientists, the effect of these changes is to vastly shrink the amount of time spent acquiring and processing data, freeing up more time for science. This shift in paradigm is lowering the threshold for entry, expanding the science community, and increasing opportunities for collaboration, while promoting scientific innovation, transparency, and reproducibility. These changes are increasing the speed of science, broadening the possibilities of what questions science can answer, and expanding participation in science.
Estimating land-surface evapotranspiration based on a first-principles primary productivity model
Authors: Tan Shen , Wang Han , Prentice Colin
Published: March 2021

Evapotranspiration (ET) links the water and carbon cycles in the atmosphere, hydrosphere and biosphere, and is of great important in earth system science, hydrology and resource management researches. Commonly used ET estimating approaches usually contains type-based parameters, which requires calibration and associates with land cover product. Parameterization structure, representativity of training group and accuracy of land cover information all influences the performance of model extrapolation. In this study, we develop an ET modelling framework based on the hypothesis that canopy conductance acclimates to plant growth conditions so that the total costs of maintaining carboxylation and transpiration capacities are minimized. This is combined with the principle of co-ordination between the light- and Rubisco-limited rates of photosynthesis to predict gross primary production (GPP). Transpiration (T) is predicted from GPP via canopy conductance. No plant type- or biome-specific parameters are used. ET is estimated from T by calibrating a site-specific (but time-invariant) ratio of modelled average T to observed average ET. Predicted GPP were well supported by (weekly) GPP records at 112 widely distributed eddy-covariance flux sites (FLUXNET 2015 dataset), with R2 = 0.61, and RMSE = 2.73gC/day (N = 30129). ET were also well supported at site scale, with R2 = 0.65, and RMSE = 0.73mm/day (N = 30129). Global ET mapping was carried out with the help of Google Earth Engine (GEE). Basin-scale water balance validation in several globally distributed watersheds also indicates the robustness of our model.
Microbial utilization of terrigenous ancient carbon released to marine environments traced by compound specific radiocarbon dating

Published: March 2021

Until two decades ago, ancient carbon was regarded as non-bioavailable substrate for organisms because it was synthesised, deposited, and once before (partially) degraded thousands to millions of years ago. Such aged organic matter is stored in terrestrial permafrost deposits or sedimentary bedrock, where it is locked up and remains disconnected from the active global carbon cycle. However, with changing climatic conditions, these organic matter reservoirs are being remobilised at faster rates by receding glaciers or permafrost thaw. During transport and after redeposition in newly formed sediments, the ancient carbon can be accessed by micro-organisms, but whether or not the micro-organisms can utilize the ancient carbon is highly debated.

Using a combined approach of lipid biomarker analysis, lipidology, and radiocarbon dating of bulk organic matter as well as single compounds targeting intact polar lipid fatty acids (IPL-FAs), our research demonstrates that microbial communities utilise supposedly non-bioavailable ancient carbon for biosynthesis in Arctic marine fjord sediments. The availability of ancient carbon to the sub-surface microbes represents a carbon source that has not been accounted for in today’s climate models. These implications are of major importance concerning the increased thawing of high latitude permafrost soils, permafrost mobilization and coastal erosion due to anthropogenic climate change, catalysing associated positive feedback loops. In future research, we will use this approach to study the utilization of ancient carbon derived from North American and Siberian permafrost soils in Arctic shelf sediments to assess its importance in the global carbon budgets.
Integrated system dynamics modelling of the water-energy-food-land-climate nexus in Latvia: exploring the impact of policy measures in a nexus-wide context
Authors: Susnik Janez , Masia Sara , Indriksone Daina , Bremere Ingrida , Vamvakeridou-Lyroudia Lydia , Brouwer Floor
Published: March 2021

The water-energy-food-land-climate nexus sectors interact in a complex system operating on many scales. Better understanding this system, and its response to change (e.g. climate change, policy implementation) is urgently required, yet little progress has been made on integrating real policy objectives into nexus models to assess potential nexus-wide impacts of policy decisions. Given current concerns on resource scarcity, and on the growing appreciation of how connected the sectors are, under-standing how the implementation of policy objectives in one area will impact (1) other nexus sectors and (2) potential future system behaviour, is becoming vitally important. Despite this, little progress has been towards such an understanding. In this work, a fully integrated system dynamics model of the water-energy-food-land-climate nexus in Latvia is presented. The model couples all the nexus sectors in a feedback driven modelling framework. Latvia is represented in five distinct yet inter-acting regions, allowing finer scale interrogation of results and policy implications. In addition, real Latvian policies are integrated within various nexus sectors (e.g. a policy to improve crop yields or to expand agricultural lands at the expense of other land use types). Due to the integrated nature of the model, executing any policy will not only have an impact within the policy sector (e.g. water), but the nexus-wide impacts can also be determined (e.g. on GHG emissions). Results show that due to the inter-connectedness, impacts range far more widely than may be anticipated. For example, implementing policies to achieve goals related to cereal land coverage in Latvia prevents the attainment of policy goals relating to emissions reductions. As such, synergies can be identified and harnessed, while trade-offs can be avoided. Policy can then be (re-)designed to maximise nexus-wide benefits. This work is carried out in the framework of the H2020 project SIM4NEXUS, which will deliver 10 more such models exploring the policy impacts on the nexus at different scales (sub-national to European). As such, the work starts to fill a crucial academic and applied knowledge gap: how policies designed for a single sector have impacts that ripple throughout the entire nexus. As such, guidelines for more intelligent policy design can start to be formulated, something that is lacking in current nexus research.
Diverse Regional Sensitivity of Summer Precipitation in East Asia to Ice Volume, CO2 and Astronomical Forcing
Authors: Lyu Anqi , Yin Qiuzhen , Crucifix Michel , Sun Youbin
Published: March 2021

The East Asian summer monsoon (EASM) is an important component of the climate system and it influences about one-third of the world’s population. Numerous paleoclimate records and climate simulations have been used to study its long-term evolution and response to different forcings. The strong regional dependence of the EASM variation questions the relative role of ice sheets and insolation on the EASM precipitation in different sub-regions in East Asia. A Gaussian emulator, which was generated and calibrated by interpolating the outputs of 61 snapshot simulations performed with the model HadCM3, is used to quantitatively assess how astronomical forcing, CO2 and northern hemisphere ice sheets affect the variation of the summer precipitation over the last 800 ky. Our results show that in the north of 25°N of the EASM domain, the variation of the summer precipitation is dominated by precession and insolation. This leads to strong 23-ky cycles in the summer precipitation. However, in the southern part (south of 25°N), the impact of ice volume becomes more important, leading to strong 100-ky cycles. Ice sheets influence the summer precipitation in the south mainly through its control on the location of the Intertropical Convergence Zone (ITCZ) which is very sensitive to ice volume. ITCZ is shifted significantly to the south under large ice sheets conditions. Therefore, the region under control of the ITCZ is more sensitive to the influence of ice volume than other regions. Our results also show that obliquity and CO2 have relatively small effect on the summer precipitation as compared to precession and ice sheets.
A full-waveform inversion workflow for estimationing ambient seismic source distributions from Rayleigh-wave multicomponent crosscorrelations
Authors: Xu Zongbo , Mikesell T. Dylan , Umlauft Josefine , Gribler Gabriel
Published: March 2021

Estimation of ambient seismic source distributions (e.g. location and strength) is important for studies of seismic source mechanisms and subsurface structures. It is current state of the art to estimate the source distribution by applying full-waveform inversion (FWI) to seismic crosscorrelations. We previously theoretically demonstrated the advantage of Rayleigh-wave multicomponent crosscorrelations in the FWI estimation process. In this presentation, we utilize the crosscorrelations from real ambient seismic data acquired in Hartoušov, Czech Republic, where the seismic sources are CO2 degassing areas at Earth’s surface (i.e. fumaroles or mofettes).  We develop a complete workflow from the raw data to the FWI estimation. We demonstrate that the multicomponent crosscorrelations can better constrain the source distribution than vertical-component crosscorrelations in both elastic media and anelastic media, even when we use an elastic forward model in the inversion process. Our inversion results indicate a strong seismic source near strong CO2 gas flux areas.
Very short-term radar rainfall prediction using deep neural network for hydropower dam operation
Authors: Yoon Seongsim , Shin Hongjoon
Published: March 2021

It is important to utilize various hydrological and weather information and accurate real-time forecasts to understand the hydrological conditions of the dam in order to make decisions of dam operation. In particular, due to rainfall concentrated in a short period of time during the flood season, it is necessary to plan the exact amount of dam discharge using real-time rainfall forecasting information. Compared to the ground rain gauge network, the radar has a high resolution of time and space, which enables the continuous expression of rainfall, which is very advantageous for very short-term prediction. Especially, In particular, the radar is capable of three-dimensional observation of the atmosphere, which has an advantage in understanding the vertical development and structure of clouds and rainfall, which can be used to observe torrential rain in the dam basin and to anticipate future rainfall intensity changes, rainfall movement and duration time. This study aims to develop a suitable radar-based very short-term rainfall prediction technique and to produce rainfall prediction information of the dam basin for stable dam operation and water disaster prevention. The radar-based rainfall prediction in this study is to be performed using a convolutional deep neural network with the 8 years weather radar data of the Korea Meteorological Administration. And, we select rainfall cases with high rainfall intensity and train the deep neural network to ensure the accuracy of flood season rainfall prediction. In addition, we intend to perform the accuracy evaluation with extrapolation-based rainfall prediction results for the dam basin.

Surface energy balance closure – the role dispersive fluxes induced by submesoscale secondary circulations
Authors: Mauder Matthias
Published: March 2021

Quantitative knowledge of the surface energy balance is essential for the prediction of weather and climate. However, a multitude of studies from around the world indicates that the turbulent heat fluxes are generally underestimated using eddy-covariance measurements, and hence, the surface energy balance is not closed. This energy balance closure problem has been heavily covered in the literature for more than 25 years, and as a result, several instrumental and methodological aspects have been reconsidered and partially revised. Nevertheless, a non-negligible energy imbalance remains, and we demonstrate that a major portion of this imbalance can be explained by dispersive fluxes in the surface layer, which are associated with submesoscale secondary circulations. Such large-scale organized structures are a very common phenomenon in the convective boundary layer, and depending on static stability, they can either be roll-like or cell-like and occur even over homogeneous surfaces. Over heterogeneous surfaces, thermally-induced mesoscale circulations can occur in addition to those. Either way, the associated dispersive heat fluxes can inherently not be captured by single-tower measurements, since the ergodicity assumption is violated. As a consequence, energy transported non-turbulently will not be sensed by eddy-covariance systems and a bias towards lower energy fluxes will result. The objective of this research is to develop a model that can be used to correct single-tower eddy-covariance data. As a first step towards this goal, we will present a parametrisation for dispersive fluxes, which was developed based on an idealized high-resolution LES study for homogeneous surfaces, as a function of non-local scaling variables. Secondly, we explore how well this parametrisation works for a number of real-world eddy-covariance sites.
Numerical simulations of anthropogenic dust
Authors: Chen Siyu
Published: March 2021

Approximately 90% of people worldwide breathe air that contains high concentrations of particulate matter (PM) pollution. Anthropogenic dust (AD), as a crucial component of PM, can be interpreted as dust emitted by modifying or disturbing soil particles through direct (e.g., construction and driving of vehicles) and indirect (e.g., wind erosion over agricultural land, grassland, dry lakes, etc.) human activities. The compositions and properties of AD are more complex and variable than those of natural dust (ND). Current studies on dust aerosols have mostly focused on ND emissions, transport, and climate effects. However, the quantitative knowledge of the sources, characteristics, and impacts of AD is inadequate.

To comprehensively reproduce the AD emissions process, both “indirect” and “direct” AD emission were constructed to simulate AD emissions originated from diverse kinds of source regions in the study. Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) retrievals were utilized as the constraint of AD simulations. Results showed that using both indirect and direct AD emission schemes show good performance on reproducing the spatio-temporal distributions of AD at the global scale. Compared with natural dust emissions, indirect AD emissions show an indistinctive seasonal variation, with seasonal differences generally less than 0.42 μg m−2 s−1. Among indirect AD emissions, pasturelands produce more AD particles emission into the atmosphere than croplands at approximately 0.28 μg m−2 s−1, contributing 75.9% of indirect AD emissions. The developing regions emit much higher direct AD emissions than those from developed regions. In addition, AD-induced surface radiative cooling of up to -10.0 W m-2 regionally, especially in the developing countries. The estimated global total premature mortality due to AD is 0.7 million deaths per year and is more severe in populous regions.

The effects of climate change on water resources and sea level are largely determined by the size of the ice reservoirs around the world, which still remains largely uncertain. Ice flow defines the transfer of ice within a glacier and therefore largely governs the spatial distribution of the ice volume. Although some individual regions have been mapped, there is to date no global and complete view of glacier flow. In this study, we present a global mapping of surface ice flow velocity and use it to revise the ice thickness distribution and volume of glaciers around the world. Glacier surface flow velocities were calculated using Sentinel-2/ESA, Landsat-8/USGS, Venμs/CNES-ISA, Pléiades/AirbusD&S and radar data from Sentinel-1/ESA. We designed an automated workflow that (i) downloads the data from institutional or commercial servers, (ii) prepares the images, (iii) launches the feature tracking algorithm, (iv) calibrate the glacier surface velocities, and (v) mosaics the results to obtain filtered and averaged velocity maps. For years 2017 and 2018, glacier surface flow velocities are quantified for every possible repeat cycles from the nominal cycle of the sensor (2-16 days) up to more than one year. This new database of glacier surface flow velocity is used to construct an updated global ice volume based on the well known Shallow Ice Approximation approach. We discuss the quality of our global glacier surface flow velocity product and of our new ice volume reconstruction with respect to existing state of the art estimates and quantify the impact of our results in terms of sea level rise and water resources.

On October 27th, 2017, a Mw 4 earthquake occurred close to the municipality of Montesano sulla Marcellana, less than 10 km external to the concession of the largest European on-shore hydrocarbon reservoir - the Val d’Agri oilfield (Southern Italy). Being a weak event located outside the extended monitoring domain of the industrial concession, the relevance of this earthquake and possible links with the hydrocarbon exploitation were not deepened. The study of weak to moderate earthquakes can improve the characterization of the potentially destructive seismic hazard of this particular area, already struck by M>6.5 episodes in the past. Taking advantage of a wide coverage of seismic stations deployed in the VA region, we analyze the source parameters of this Mw 4 earthquake applying advanced seismological techniques to estimate the uncertainties derived from the moment tensor inversion and identify plausible directivity effects. The moment tensor is dominated by a NW-SE oriented normal faulting with a centroid depth of 14 km. A single ML 2.1 aftershock was recorded and used as empirical Green function to calculate the apparent source time function for the mainshock. Apparent durations (in the range 0.11 - 0.21 s, obtained from S-waves) define an azimuthal pattern which reveals an asymmetric bilateral rupture with the 70% of the rupture propagation in the N310°W direction, suggesting a rupture plane dipping to the SW. Our results conclude that the Montesano earthquake activated a deeper fault segment associated to the Eastern Agri Fault System close to the basement. The relative low trigger potential below 10% based on depletion-induced stress changes discards an induced or triggered event due to the long-term hydrocarbon extraction in the Val d’Agri oilfield, and it rather suggests a natural cause due to the local tectonic stress.
The meltwater feedbacks on ice dynamics, influence of melt amplitude, duration and extent.

In recent years, temperatures over the Greenland ice sheet have been rising, leading to an increase in surface melt. This increase however can not be reduced to a simple number. Throughout the recent years we have seen some extreme melt seasons with melt extending over the whole surface of the ice sheet (2012) or melt seasons of lower amplitudes but with a longer duration (2010). The effect of those variations on the subglacial system and hence on ice dynamic are poorly understood and are still mainly deduced from studies based on mountain glaciers.

Here we apply the Ice-sheet and Sea-level System Model (ISSM) to a synthetic glacier with a geometry similar to a Greenland ice sheet land terminating glacier. The forcing is designed such that it allows to investigate different characteristics of the melt season: its length, intensity or the spatial extension of the melt. Subglacial hydrology and ice dynamics are coupled within ISSM is coupled to a subglacial hydrology model, allowing to study the response of the system in terms of subglacial water pressure and the final impact on ice dynamics. Of particular interest is the evolution of the distribution of the efficient and inefficient component of the subglacial drainage system which directly impacts the water pressure evolution at the base of the glacier.

We note that the initiation of the melt season and the intensity of the melt at this period is a crucial parameter when studying the dynamic response of the glacier to different melt season characteristics. From those results, we can infer a more precise evolution of the dynamics of land terminating glaciers that are heavily driven by their subglacial drainage system. We also highlight which changes in the melt season pattern would be the most damageable for glacier stability in the future.

Emissions of biogenic aerosols such as allergenic pollen affect the public health badly. In combination with air pollution it puts additional distress on people already suffering from cardiovascular and respiratory diseases. In some European countries the prevalence of people with pollinosis is up to 40%. In Belgium, ~10% is sensitive for birch pollen. Patients suffering from pollinosis in Belgium lack access to detailed real-time spatial information and warnings on forthcoming pollen exposures. This is because the only pollen info is coming from five aerobiological stations which monitor off-line daily concentrations of airborne pollen from birches. Only two stations have almost four decades of observations, Brussels from 1982 on and De Haan from 1984 on. Chemistry Transport Models (CTM) can both quantify as well as forecast the spatial and temporal distribution of airborne birch pollen concentrations if the distributions of birch pollen emission sources over time are available.

Here we show the results of the modelled spatio-temporal distributions of almost four decades of birch pollen levels over Belgium using the CTM SILAM (http://silam.fmi.fi). This CTM is driven with the ERA5 meteorological reanalysis from ECMWF, and reconstructed birch tree fraction maps. A recent in-house birch map of Belgium derived from forest inventory data is combined with long-term series of the AVHRR-GIMMS3g NDVI to produce birch fraction maps for each year.

For the first time in Belgium, we present time series of modelled birch pollen levels by SILAM compared with daily observations from the aerobiological surveillance network for the period 1982-2019. Preliminary modelling results for Brussels show an overall R² value of 0.40 computed from modelled and observed daily birch pollen levels. The R² values for the individual birch pollen seasons may range from 0.10 to 0.82 with a median value of 0.53. For De Haan the R² values tend to be lower with the median seasonal value of 0.30. Temporal trends computed on the first results of the modelled daily values based on the Theil Sen slope and the Area Under the Curve (AUC) show a substantial increase of birch pollen levels for most parts in Belgium. This agrees well with literature reports.
The Bigger, The Better? – Paleomagnetic recording fidelity of weakly interacting clusters of particles, and implications for micro-scale paleomagnetism
Authors: Berndt Thomas , Han Chen , Devienne Jose
Published: March 2021

A recent trend in paleomagnetism is the study of samples of ever decreasing sizes, going down to (sub)millimeter scales and even microscopic scales, including single-silicate-crystals and meteorites. Microscopic imaging has shown that some of these micro-scale samples appear to be much closer to ideal single-domain (SD) paleomagnetic recorders than bulk rocks. Small samples with large numbers of SD particles do, however, pose the problem of magnetic interactions affecting their paleomagnetic recording fidelity. We show that clusters of particles are common in micro-scale samples and that these interactions do affect thermoremanent magnetization (TRM) acquisition. We further show through numerical simulations that such interacting clusters may be difficult to detect in traditional experiments (such as FORC diagrams), but may nonetheless lead to over- or underestimates in paleointensities.
