We use the Fundamental Plane (FP) to measure the redshift evolution of the dynamical mass-to-light ratio (M
dyn/L) and the dynamical-to-stellar mass ratio (M
dyn/M
*). Although conventionally used to study the properties of early-type galaxies, we here obtain stellar kinematic measurements from the Large Early Galaxy Astrophysics Census (LEGA-C) Survey for a sample of ∼1400 massive (

) galaxies at 0.6 < z < 1.0 that span a wide range in star formation activity. In line with previous studies, we find a strong evolution in M
dyn/L

g
with redshift. In contrast, we find only a weak dependence of the mean value of M
dyn/M
* on the specific star formation rate, and a redshift evolution that likely is explained by systematics. Therefore, we demonstrate that star-forming and quiescent galaxies lie on the same, stable mass FP across 0 < z < 1, and that the decrease in M
dyn/L

g
toward high redshift can be attributed entirely to evolution of the stellar populations. Moreover, we show that the growth of galaxies in size and mass is constrained to occur within the mass FP. Our results imply either minimal structural evolution in massive galaxies since z ∼ 1, or a tight coupling in the evolution of their morphological and dynamical properties, and establish the mass FP as a tool for studying galaxy evolution with low impact from progenitor bias.

Published: November 2020

Three new species of oak gall wasps of the genusAmphibolipsReinhard, 1865 (Hymenoptera: Cynipidae: Cynipini) are described from Mexico:Amphibolips magnigallaNieves-Aldrey & Castillejos-Lemus,Amphibolips kinseyiNieves-Aldrey & Castillejos-Lemus andAmphibolips nigrialatusNieves-Aldrey & Castillejos-Lemus. The specimens of the first two species were representative of sexual generations and come from the State of Oaxaca, while only a female, collected in the State of Veracruz, is described forA. nigrialatus. The new species induces galls onQuercus zempoaltepecanaandQ. sapotifolia(Fagaceae, section Lobatae, red oaks). Descriptions of the diagnostic morphological characteristics of the three species and a key for their identification are provided. The taxonomic relationships of the new species with other species ofAmphibolipsare discussed; the three new species are closely allied amongst themselves and are related toA. dampfiKinsey, 1937. With the three newly-described species, the number ofAmphibolipsin Mexico is increased to 23.

Published: November 2020

Sitophilus zeamais Motschulsky, 1855 (Coleoptera: Curculionidae) which develops inside the grain, is an aggressive pest of stored grains. Here, we evaluated the efficiency of diatomaceous earth (DE), Diatomita CI/325 CX, and dolomite (DOL), Dolomita Dr. Kanyo, against S. zeamais reared on corn under laboratory conditions and observed external alterations on treated insects using scanning electron microscopy (SEM). Insects treated with both DE and DOL were impregnated with particles on the body surface, and they showed 100% mortality after 10 days of exposure. Damages caused by inert dusts may have contributed to dehydration and desiccation, consequently, leading insects to death. Thus, diatomaceous and dolomite were effective against S. zeamais under laboratory conditions.
Pauvreté féminine et VIH en Éthiopie
Authors: De Rosis Carolina
Published: November 2020

Cet article interroge, d’un point de vue anthropologique, la condition de pauvreté de femmes vivant avec le VIH. Après avoir décrit l’enchevêtrement des politiques de lutte contre cette épidémie et des programmes de réduction de la pauvreté, l’auteure étudie les rôles que le VIH a joués tant au plan de l’identification des femmes pauvres et des manières de leur venir en aide qu’au sein de leurs parcours de sortie de la pauvreté. L’article démontre ainsi que les stratégies de prise en charge globale du VIH participent à divers parcours de mobilité sociale, tout en contribuant à des processus de reproduction des inégalités de santé et de diversification de leur expression.
Tontines et prostitution à Château-Rouge
Authors: Nguié Habib Marius
Published: November 2020

Cet article porte sur les tontines et la prostitution de rue au sein du marché noir-africain de Château-Rouge, à Paris. Si certaines femmes congolaises rencontrées ont autofinancé leur voyage pour rejoindre la capitale française, d’autres en revanche ont contracté des prêts. L’argent du commerce ne permettant pas de rembourser rapidement leurs dettes, ces immigrées se prostituent et « lavent » ensuite l’argent issu de cette activité dans la tontine, ce qui leur permet par ailleurs de valoriser symboliquement leur travail.
Les organisations paysannes au Paraguay

Published: November 2020

Alors que le Paraguay a célébré en février 2019, le trentième anniversaire du coup d’État qui a mis fin à la dictature d’Alfredo Stroessner et inauguré un processus de transition démocratique, certes chaotique mais effectif, cet article entend centrer son analyse sur un acteur oublié du renouveau institutionnel et politique : le mouvement paysan. De fait, en dépit de son importance numérique et de sa grande capacité de mobilisation, l’empreinte politique du mouvement paysan dans un pays considéré comme l’un des plus inégalitaires au monde en matière de répartition foncière apparaît finalement réduite. Sur la base d’une lecture approfondie de la littérature académique sur le sujet, nous tâchons de comprendre les raisons qui expliquent l’impuissance de ce mouvement à peser sur l’agenda politique.
Pour un nouveau paradigme de la formation des maîtres : des cliniques de l’éducation
Authors: Prot Frédérique Marie
Published: November 2020

Notre proposition s'inscrit dans la lignée des travaux sur l'universitarisation de la formation des maîtres. Réfléchissant sur le hiatus qui sépare les préoccupations des chercheurs et celles des professeurs, Sensevy (2011) a proposé en Théorie de l'Action Conjointe en Didactique un nouveau paradigme de la formation qu'il a conçu sur le modèle des cliniques médicales. L'instrument de telles cliniques serait des ingénieries didactiques coopératives élaborées conjointement entre chercheurs et professeurs, visant à constituer une science de l'action conjointe. Cette élaboration commune nous conduit à penser un nouveau modèle de la formation des maîtres en tant que processus d'enquête sur le métier mené conjointement par chercheurs et professeurs en formation. Ce modèle s’appuie sur l’expérience empirique de l’Institut Freinet de Vence.

Acute graft-versus-host disease (aGVHD) is one major serious complication that is induced by alloreactive donor T cells recognizing host Ags and limits the success of allogeneic hematopoietic stem cell transplantation. In the current studies, we identified a critical role of Kras in regulating alloreactive T cell function during aGVHD. Kras deletion in donor T cells dramatically reduced aGVHD mortality and severity in an MHC-mismatched allogeneic hematopoietic stem cell transplantation mouse model but largely maintained the antitumor capacity. Kras-deficient CD4 and CD8 T cells exhibited impaired TCR-induced activation of the ERK pathway. Kras deficiency altered TCR-induced gene expression profiles, including the reduced expression of various inflammatory cytokines and chemokines. Moreover, Kras deficiency inhibited IL-6–mediated Th17 cell differentiation and impaired IL-6–induced ERK activation and gene expression in CD4 T cells. These findings support Kras as a novel and effective therapeutic target for aGVHD.

Preclinical studies demonstrated that complement promotes tumor growth. Therefore, we sought to determine the best target for complement-based therapy among common human malignancies. High expression of 11 complement genes was linked to unfavorable prognosis in renal cell carcinoma. Complement protein expression or deposition was observed mainly in stroma, leukocytes, and tumor vasculature, corresponding to a role of complement in regulating the tumor microenvironment. Complement abundance in tumors correlated with a high nuclear grade. Complement genes clustered within an aggressive inflammatory subtype of renal cancer characterized by poor prognosis, markers of T cell dysfunction, and alternatively activated macrophages. Plasma levels of complement proteins correlated with response to immune checkpoint inhibitors. Corroborating human data, complement deficiencies and blockade reduced tumor growth by enhancing antitumor immunity and seemingly reducing angiogenesis in a mouse model of kidney cancer resistant to PD-1 blockade. Overall, this study implicates complement in the immune landscape of renal cell carcinoma, and notwithstanding cohort size and preclinical model limitations, the data suggest that tumors resistant to immune checkpoint inhibitors might be suitable targets for complement-based therapy.
TGF-β1-regulated miR-3691-3p targets E2F3 and PRDM1 to inhibit prostate cancer progression

Published: November 2020

Transforming growth factor-β1 (TGF-β1) acts as a tumor promoter in advanced prostate cancer (PCa). We speculated that microRNAs (miRNAs) that are inhibited by TGF-β1 might exert anti-tumor effects. To assess this, we identified several miRNAs downregulated by TGF-β1 in PCa cell lines and selected miR-3691-3p for detailed analysis as a candidate anti-oncogene miRNA. miR-3691-3p was expressed at significantly lower levels in human PCa tissue compared with paired benign prostatic hyperplasia tissue, and its expression level correlated inversely with aggressive clinical pathological features. Overexpression of miR-3691-3p in PCa cell lines inhibited proliferation, migration, and invasion, and promoted apoptosis. The miR-3691-3p target genes E2F transcription factor 3 (E2F3) and PR domain containing 1, with ZNF domain (PRDM1) were upregulated in miR-3691-3p-overexpressing PCa cells, and silencing of E2F3 or PRDM1 suppressed PCa cell proliferation, migration, and invasion. Treatment of mice bearing PCa xenografts with a miR-3691-3p agomir inhibited tumor growth and promoted tumor cell apoptosis. Consistent with the negative regulation of E2F3 and PRDM1 by miR-3691-3p, both proteins were overexpressed in clinical PCa specimens compared with noncancerous prostate tissue. Our results indicate that TGF-β1-regulated miR-3691-3p acts as an anti-oncogene in PCa by downregulating E2F3 and PRDM1. These results provide novel insights into the mechanisms by which TGF-β1 contributes to the progression of PCa.

Purpose The occurrence pattern of immune-related adverse events (irAEs) induced by immune checkpoint inhibitor (ICI) in cancer treatment remains unclear. Materials and Methods Phase II-III clinical trials that evaluated ICI-based treatments in cancer and were published between January 2007 and December 2019 were retrieved from public electronic databases. The pooled median time to onset (PMT-O), resolution (PMT-R), and immune-modulation resolution (PMT-IMR) of irAEs were generated using the metamedian package of R software.Results Twenty-two eligible studies involving 23 clinical trials and 8,436 patients were included. The PMT-O of all-grade irAEs ranged from 2.2 to 14.8 weeks, with the longest in renal events. The PMT-O of grade ≥ 3 irAEs was significantly longer than that of all-grade irAEs induced by programmed cell death protein 1 (PD-1) and its ligand 1 (PD-L1) inhibitors (27.5 weeks vs. 8.4 weeks, p < 0.001) and treatment of nivolumab (NIV) plus ipilimumab (IPI) (7.9 weeks vs. 6.0 weeks, p < 0.001). The PMT-R of all-grade irAEs ranged from 0.1 to 54.3 weeks, with the shortest and longest in hypersensitivity/infusion reaction and endocrine events, respectively. The PMT-IMR of grade ≥ 3 irAEs was significantly shorter than that of all-grade irAEs caused by PD-1/PD-L1 blockade (6.9 weeks vs. 40.6 weeks, p=0.002) and NIV+IPI treatment (3.1 weeks vs. 5.9 weeks, p=0.031).Conclusion This study revealed the general and specific occurrence pattern of ICI-induced irAEs in pan-cancers, which was deemed to aid the comprehensive understanding, timely detection, and effective management of ICI-induced irAEs.

Abstract

Objective: Clinicopathological features of gastroenteropancreatic neuroendocrine tumors (GEP-NETs) have rarely been studied in the Pakistani population. We investigated the clinical characteristics of these tumors according to the updated World Health Organization (WHO) 2010 classification.

Methods: The data of Shifa International Hospital, Islamabad was retrospectively analysed for pathologically confirmed GEP-NETs from January 2013 to March 2018.

Results: One hundred and eighteen patients (mean age, 52.2 years; male, 55.1%) were identified. 83.1% of the patients were symptomatic including5.1% functional tumors. Pancreas (28%) was the most frequent primary site noted. The most common histologic type was well differentiated neuroendocrine tumor (WDNET) in 81.4% followed by neuroendocrine carcinoma (NEC) in 16.1%. 45.8% cases of WDNET were grade 1, 27.1% were grade 2, and 8.5% were grade 3.15.3% had distant metastasis at the time of diagnosis with liver (77.7%) as the most common metastatic site. Synaptophysin positivity was seen in 96.8% of grade 1 & grade 2 WDNET, 100% of grade 3 WDNET and 92.3% of NEC and chromogranin was positive in 94.2% of grade 1 &grade 2 WDNET, 83.3% of grade 3 WDNET and 45.4% of NEC.

Conclusion: GEP-NETs showed a wide clinicopathological spectrum. Pancreas is the most site of involvement by the GEP-NET however grade 3 WDNET had a predilection for the colon. Small cell carcinomas were commonly observed in esophagus.

Síndrome de Cushing ectópico. A propósito de un caso.
Authors: Cherner Kevorkian Dra. Marcela , Navarro Hidalgo Dra. Inmaculada , Rey Nodar Dr. Severino , Roig Espert Dra. Belén
Published: November 2020

Ectopic Cushing syndrome is an infrequent cause of hypercortisolism characterized by the secretion of adrenocorticotropic hormone (ACTH) by tumors with neuroendocrine differentiation, such as small cell carcinoma of the lung, bronchial carcinoid, medullary carcinoma thyroid, thymic carcinoma and pancreatic neuroendocrine tumors, among others. The ACTH-dependent Cushing syndrome due to an ectopic tumor accounts for approximately 15% of endogenous Cushing syndrome and, depending on the aggressiveness of the tumor, the manifestations of hypercortisolism may be evident or not. We report a 61-year-old man who consulted for edema of the face and lower limbs, asthenia and cutaneous herpes zoster in the cervical region which during the clinical-radiological studies was diagnoses of two large retroperitoneal masses histologically corresponding to an ACTH-producing neuroendocrine tumor.

Published: November 2020

There has been a great deal of research activity focusing on the relationship between insulin resistances (IR), hyperlidemia and Rheumatic arthritis (RA). It appears to be a general agreement that IR and hyperlipidaemia are commonly seen in patinas with RA. A case-control study was done among 45 RA patients and 42 healthy controls. The study was conducted in the outpatient department of Bangabandhu Sheikh Mujib Medical University (BSMMU). A structured questionnaire was used to collect data through face-to-face interview. TO and LDL were significantly higher and HDL was lower in comparison to those of control and associated with IR. Hyperlipidemias are associated with RA in Bangladeshis.

The Machine is Doing the Work: Interview with Nicholas Mirzoeff

Optical and mechanical tools were the first major “augmentation” of human senses. The microscope approached the worlds that were too small for the optical performance of the eye. The telescope touched the too far-off space; X-rays radiated the inaccessible interior of the body. Such augmentations were not innocent, as they demanded a different interpretation of the world, which would correspond to images of infinitely small, remote or hidden. Similar augmentation is now happening with cloud computing, machine vision and artificial intelligence. With these tools, it may be possible to compile and analyze billions of digital images created daily by people and machines. But who will analyze these images and for what purpose? Will they help us to better understand society and learn from past mistakes? Or have they already been hijacked by attention-merchants and political demagogues who are effectively spreading old ideologies with new communication technologies?

Reflections on Photogrammetry
Authors: W. Schindler Alexander
Published: November 2020

This article presents an overview of the history, principles, and current developments in the media technological field of photogrammetry. By chronicling the isomorphic shift taking place in image capturing, we seek to show that photogrammetry has led the way forward in seeing technical images not only as two dimensional projections, but as three-dimensional model-based images. In the mid-nineteenth century, photogrammetry was first used for the documentation of architectural objects and it later became a standard technique in aerial photography. Although its fields of application have become more extensive, photogrammetry’s basic principle hasn’t fundamentally changed: it is still defined as the three- dimensional geometric reconstruction of two-dimensional photographs through the measuring of reference points. With digital technological standards and advances in camera technology, photogrammetric imaging nowadays is intensively used for object recognition in machine vision and robotics. Beside this, photogrammetry is also opening new possibilities for documentation in the fields of investigative arts, this being explored with a discussion on the “Ground Truth” project from Forensic Architecture.

The Incompleteness of Lookings
Authors: Hillman John
Published: November 2020

Augmented reality is fundamentally different from virtual reality: it does not map a real world environment into a digital one as a virtual experience. Instead, it locates both reality and virtual within the same experiential frame. Through it, our interactions with reality are mediated via the fantasy of an augmented experience. Thus, augmented reality supplements what we see with the purpose of trying to maintain our attention. What is most fascinating about augmented reality is how reality itself becomes a part of, rather than distinct from, digital information. It is in this sense that the very notion of seeing is fundamentally challenged. Since when augmented technology is not deployed, what is left is an apparent incompleteness of simply looking. But what are the consequences of confronting this incompleteness? In this article I examine how augmented reality simply renders a structure that has always sustained the visual field.

Perspective and Memory in Photographic Images
Authors: Whitlock Richard
Published: November 2020

Digital imaging may have tied us to the computer keyboard, but it allows us to recuperate for photography the freedom and control that painters and draughtsmen have always had when reconstructing space on a flat surface. Angles of vision can be explored beyond the normal reach of the human eye or the camera lens. For the last few years I have concentrated in particular on the application of orthographic projection to photographic images, both moving and still. I have found that removing the conventional perspective has the effect of defamiliarising and enriching what we see: objects seem to pass directly into memory not as images but as realities.

Nature of AECI is a complex array of interdependent activities-best organized chaos introducing challenges not encountered in other industries. The work is often seasonal; Each project is unique; Often involves remote sites with various access problems; The process is not as predictable; There is difficulty in applying automation; There is high potential for encountering unforeseen conditions; Costs can vary according to conditions; There is difficult to manage and supply utilities and other resources; Technical innovations are adopted at slower pace; Success is dependent upon the quality of its people; AECI is very customoriented; Products can be of mind-boggling size, cost, and complexity; The work is not performed in controlled conditions, therefore highly impacted by weather and other environmental conditions. Over 100 Surveys, case studies and literature studies were done and it is found that the AECI faces several increasing & complicated construction and non-construction challenges, of all these few are new and rest centuries old. This extensive exploratory research was carried out to explore all the AECI challenges that affect AECI PDLC processes and this research suggests the remedial measures specifically to housing sector, addresses AECI challenges that help to improve productivity and efficiencies in the AECI processes.

Published: November 2020

India is one of the largest consumergoods market in the world. However, with the growing consumption of electronics and IT goods in the country, the environmental threat posed by E-waste has touched an alarming level.‘E-waste’ is a collective name for discarded electronics devices that enter the waste stream from various sources that include electronic appliances such as discarded computers, televisions, VCRs, cell phones, batteries etc. In concern with the environment and its healthy living, the government has undertaken many reforms and policies to mitigate the impact of e-waste. For instance, Corporate Responsibility for Environmental Protection (CREP) 2003, Hazardous Wastes (Management and Handling) Rules, 1989 etc. These reforms have brought out several impacts in the industrial sector and have a huge impact in the making of the products and their selling. Our paper portrays the impacts of the Supply Change Management techniques which led to the design of innovative steps and practices undertaken by the industries like reverse logistics, RFID tools etc to reduce the E-waste in the recent past.

Published: November 2020

Objectives. The study aims to determine whether there is an association of perceived weight status with unhealthydiet practices.

Method. An analytic cross-sectional study was conducted among 625 adult undergraduate students from U.P.Manila. The survey included questions regarding sociodemographic status, habits related to diet and weightmanagement, and perceived body mass index (BMI). Actual BMI were obtained and calculated from actualanthropomorphic measurements.

Results. In the population surveyed, it was seen that 53.28% of the students accurately perceived their BMIstatus, 26.08% overestimated their BMI status, while 17.28% underestimated their BMI status. It was also seenthat over-estimating of BMI status is more associated with unhealthy diet practices. Those who over estimatedtheir BMI were 1.95 times more likely to skip meals (p=0.001) and 1.56 times more likely to engage in cuttingof food (p=0.034). Physical activity was also seen to be associated with these practices.

Conclusion. Over-estimation of BMI may be linked to unrealistic goals in weight loss resulting in unhealthierdiet-related habits.

Scattering and Absorption Cross-sections of Atmospheric Gases in the
Ultraviolet-Visible Wavelength Range (307–725 nm)

Published: November 2020

Abstract. Accurate Rayleigh scattering and absorption cross-sections of atmospheric gases are essential for understanding the propagation of electromagnetic radiation in planetary atmospheres. Accurate extinction cross-sections are also essential for calibrating high finesse optical cavities and differential optical absorption spectroscopy and for accurate remote sensing. In this study, we measured the scattering and absorption cross-sections of carbon dioxide, nitrous oxide, sulfur hexafluoride, oxygen, and methane in the continuous wavelength range of 307–725 nm using Broadband Cavity Enhanced Spectroscopy (BBCES). The experimentally derived Rayleigh scattering cross-sections for CO2, N2O, SF6, O2, and CH4 agree with refractive index-based calculations, with a difference of 1.5 % and 1.1 %, 1.5 %, 2.9 %, and 1.4 % on average, respectively. The O2-O2 collision-induced absorption and absorption by methane are obtained with high precision at the 0.8 nm resolution of our BBCES instrument in the 307–725 nm wavelength range. New dispersion relations for N2O, SF6, and CH4 were derived using data in the UV-vis wavelength range. This study provides improved refractive index dispersion relations, n-based Rayleigh scattering cross-sections, and absorption cross-sections for these gases.

Abstract. This paper presents measurements of mineral dust concentration in the diameter range from 0.4 to 14.0 μm with a novel balloon-borne optical particle counter, the Universal Cloud and Aerosol Sounding System (UCASS). The balloon launches were coordinated with ground-based active and passive remote-sensing observations and airborne in-situ measurements with a research aircraft during a Saharan dust outbreak over Cyprus from 20 to 23 April 2017. The aerosol optical depth at 500 nm reached values up to 0.5 during that event over Cyprus and particle number concentrations were as high as 50 cm−3 for the diameter range between 0.8 and 13.9 μm. Comparisons of the total particle number concentration and the particle size distribution from two cases of balloon-borne measurements with aircraft observations show reasonable agreement in magnitude and shape despite slight mismatches in time and space. While column-integrated size distributions from balloon-borne measurements and ground-based remote sensing show similar coarse-mode peak concentrations and diameters, they illustrate the ambiguity related to the missing vertical information in passive sun photometer observations. Extinction coefficient inferred from the balloon-borne measurements agrees with those derived from coinciding Raman lidar observations at height levels with particle number concentrations smaller than 10 cm−3 for the diameter range from 0.8 to 13.9 μm. An overestimation of the extinction coefficient of a factor of two was found for layers with particle number concentrations that exceed 25 cm−3. This is likely the result of a variation in the refractive index, the shape- and size-dependency of the extinction efficiency of dust particles along the UCASS measurements.
Solar tracker with optical feedback and continuous rotation

Published: November 2020

Abstract. Solar trackers are often used by spectrometers to measure
atmospheric trace gas concentrations using direct sun spectroscopy. The
ideal solar tracker should be sufficiently accurate, highly reliable, and
with a longevity that exceeds the lifetime of the spectrometer that it
serves. It should also be affordable, easy to use, and not too complex should
maintenance be required. In this paper we present a design that fulfils
these requirements using some simple innovations. Our altitude–azimuth
design features a custom coaxial power transformer, enabling continuous
360∘ azimuth rotation. This increases reliability and avoids the
need to reverse the tracker each day. In polar regions, measurements can
continue uninterrupted through the summer polar day. Tracking accuracy is
enhanced using a simple optical feedback technique that adjusts error
offset variables while monitoring the edges of a focused solar image with
four photodiodes. Control electronics are modular, and our software is
written in Python, running as a web server on a recycled laptop with a Linux
operating system. Over a period of 11 years we have assembled four such
trackers. These are in use at Lauder (45∘ S), New Zealand, and
Arrival Heights (78∘ S), Antarctica, achieving a history of good
reliability even in polar conditions. Tracker accuracy is analysed regularly
and can routinely produce a pointing accuracy of 0.02∘.

Abstract. The modification of an existing cloud property retrieval scheme for the Spinning Enhanced Visible and Infrared Imager (SEVIRI) instrument onboard the geostationary METEOSAT satellites is described to utilize its high-resolution visible (HRV) channel for increasing the spatial resolution of its physical outputs. This results in products with a nadir spatial resolution of 1 × 1 km2, compared to the standard 3 × 3 km2 resolution offered by the narrowband channels. This improvement thus greatly reduces the resolution gap between current geostationary and polar-orbiting meteorological satellite imagers. In the first processing step, cloudiness is determined from the HRV observations by a threshold-based cloud masking algorithm. Subsequently, a linear model that links the 0.6 μm, 0.8 μm, and HRV reflectances provides a physical constraint to incorporate the spatial high-frequency component of the HRV observations into the retrieval of cloud optical depth. The implementation of the method is described, including the ancillary datasets used. It is demonstrated that the omission of high-frequency variations in the cloud-absorbing 1.6 μm channel results in comparatively large uncertainties in the retrieved cloud effective radius, likely due to the mismatch in channel resolutions. A newly developed downscaling scheme for the 1.6 μm reflectance is therefore applied to mitigate the effects of this scale mismatch. Benefits of the increased spatial resolution of the resulting SEVIRI products are demonstrated for three example applications: (i) for a convective cloud field, it is shown that significantly better agreement between the distributions of cloud optical depth retrieved from SEVIRI and from collocated MODIS observations is achieved; (ii) the temporal evolution of cloud properties for a growing convective storm at standard and HRV spatial resolutions are compared, illustrating an improved contrast in growth signatures resulting from the use of the HRV channel; (iii) an example of surface solar irradiance, determined from the retrieved cloud properties, is shown, where the HRV channel helps to better capture the large spatio-temporal variability induced by convective clouds. These results suggest that incorporating the HRV channel in the retrieval has potential for improving METEOSAT-based cloud products for several application domains.
Global ocean dimethyl sulfide climatology estimated from observations and an artificial neural network

Published: November 2020

Abstract. Marine dimethyl sulfide (DMS) is important to climate due to the ability of DMS
to alter Earth's radiation budget.
Knowledge of the global-scale distribution, seasonal variability, and sea-to-air flux of DMS is needed in order to improve understanding of atmospheric sulfur, aerosol/cloud dynamics, and albedo.
Here we examine the use of an artificial neural network (ANN) to extrapolate
available DMS measurements to the global ocean and produce a global climatology
with monthly temporal resolution.
A global database of 82 996 ship-based DMS measurements in surface waters was
used along with a suite of environmental parameters consisting of
latitude–longitude coordinates, time of day, time of year, solar radiation,
mixed layer depth, sea surface temperature, salinity, nitrate, phosphate, and
silicate.
Linear regressions of DMS against the environmental parameters show that on a
global-scale mixed layer depth and solar radiation are the strongest predictors
of DMS.
These parameters capture ∼9 % and ∼7 % of the raw DMS data variance,
respectively.
Multilinear regression can capture more of the raw data variance (∼39 %) but
strongly underestimates DMS in high-concentration regions.
In contrast, the artificial neural network captures ∼66 % of the raw data
variance in our database.
Like prior climatologies our results show a strong seasonal cycle in surface
ocean DMS with the highest concentrations and sea-to-air fluxes in the high-latitude
summertime oceans.
We estimate a lower global sea-to-air DMS flux (20.12±0.43 Tg S yr−1)
than the prior estimate based on a map interpolation method when the same gas transfer velocity parameterization is used.
Our sensitivity test results show that DMS concentration does not change unidirectionally with each of the environmental parameters, which emphasizes the interactions among these parameters.
The ANN model suggests that the flux of DMS from the ocean to the atmosphere will increase with global warming.
Given that larger DMS fluxes induce greater cloud albedo, this corresponds to a negative climate feedback.
