SAMI3 data in netCDF format (2019-May-13)
<p>SAMI3 (Sami3 is Also a Model of the Ionosphere) is a seamless, three-dimensional, physics-based model of the ionosphere (Huba et al, 2008). It is based on SAMI2, a two-dimensional model of the ionosphere (Huba et al., 2000). <br><br>SAMI3 models the plasma and chemical evolution of seven ion species (H⁺, He⁺, N⁺, O⁺, N⁺₂, NO⁺ and O⁺₂). The temperature equation is solved for three ion species (H⁺, He⁺ and O⁺) and for the electrons. Ion inertia is included in the ion momentum equation for motion along the geomagnetic field. This is important in modeling the topside ionosphere and plasmasphere where the plasma becomes collisionless. <br><br>SAMI3 includes 21 chemical reactions and radiative recombination, and uses a nonorthogonal, nonuniform, fixed grid for the magnetic latitude range +/- 89 degrees.. <br><br><b>Drivers</b><br>Neutral composition, temperature, and winds: NRLMSISE00 (Picone et al., 2002) and HWM14 (Drob et al., 2015). <br>Solar radiation: Flare Irradiance Spectral Model version 2 (FISM v2)<br>Magnetic field: Richmond apex model [Richmond, 1995]. <br>Neutral wind dynamo electric field: Determined from the solution of a 2D potential equation [Huba et at., 2008]. <br>For the SAMI3/Weimer configuration: High latitude electric field: calculated from the empirical Weimer model for the potential. <br>For the SAMI3/AMPERE configuration: High latitude electric field: calculated using the Magnetosphere-Ionosphere Coupling solver (MIX) developed by Merkin and Lyon (2010).

Identificación del daño genotóxico ocasionado por exposición al BTEX en trabajadores de la industria del calzado en Bucaramanga entre 2019-2020 mediante la técnica convencional de micronúcleos
<p>A nivel mundial se estima que 12,6 millones de muertes son atribuidas a causas ambientales, lo que representan el 23% de todas las muertes mundiales y en Colombia corresponde al 16%, de modo que algunas enfermedades pueden ser prevenibles a través de la modificación de factores asociados a la contaminación del aire tanto en espacios cerrados como abiertos. La exposición ocupacional y ambiental a diversos productos químicos puede causar la aparición de neoplasias malignas en una amplia variedad de órganos y tejidos, como la leucemia (por el benceno). Esto refuerza el estrecho vínculo entre el cáncer y el ambiente. En Colombia existen algunas sustancias carcinogénicas del grupo 1 de exposición ocupacional incluido el benceno. Según el Departamento Administrativo Nacional de Estadística – DANE, este solvente es una sustancia química de amplio uso industrial. En Bucaramanga, aún existen fábricas de calzado que utilizan pegantes a base de solventes que contienen benceno, lo que puede causar daño genético y epigenético, generando cáncer. El objetivo de este trabajo es determinar la asociación entre la exposición ocupacional al BTEX y las alteraciones genéticas en los trabajadores expuestos de la industria del calzado de Bucaramanga en el periodo de 2019-2020. El proyecto hace parte de un proyecto macro avalado por Minciencias . Es un estudio experimental de corte transversal; previo consentimiento informado, se tomaron muestras de sangre periférica y se empleó la técnica de micronúcleos en 2 x 500 células binucleadas. Hasta la fecha, se ha analizado la información sociodemográfica obtenida de 139 trabajadores. En la actualidad se han analizado por la técnica de micronúcleos convencional 57 muestras, los expuestos presentaron un promedio de 7.25 micronúcleos en 500 células binucleadas, mientras que los no expuestos 5.02 ± 3.5 (DS). El gran reto de este proyecto es aportar información actualizada sobre la carga de enfermedad asociada a la exposición del BETX en la ciudad de Bucaramanga, lo cual permitirá la intervención de población afectada a través de la academia y entes gubernamentales mediante el desarrollo de estrategias efectivas a corto y largo plazo, para reducir la morbilidad atribuible a las exposiciones ambientales y laborales por esta y otras sustancias químicas ocupacionales.</p>
iNaturalist data for: Multi-taxon biodiversity responses to the 2019–2020 Australian megafires
<p><span>Conditions conducive to fires are becoming increasingly common and widespread under climate change. Recent fire events across the globe have occurred over unprecedented scales, affecting a diverse array of species and habitats. Understanding biodiversity responses to such fires is critical for conservation. Quantifying post-fire recovery is problematic across taxa, from insects to plants to vertebrates, especially at large geographic scales. Novel datasets can address this challenge. We use presence-only citizen science data from iNaturalist, collected before and after the 2019-2020 megafires in burnt and unburnt regions of eastern Australia, to quantify the effect of post-fire diversity responses, up to 18 months post-fire. The geographic, temporal, and taxonomic sampling of this dataset was large, but sampling effort and species discoverability were unevenly spread. We used rarefaction and prediction (iNEXT) with which we controlled sampling completeness among treatments, to estimate diversity indices (Hill numbers: q=0-2) among nine broad taxon groupings and seven habitats, including 3885 species. We estimated an increase in species diversity up to 18 months after the 2019–2020 Australian megafires in regions which were burnt, compared to before the fires in burnt and unburnt regions. Diversity estimates in dry sclerophyll forest matched and likely drove this overall increase post-fire, while no taxon groupings showed clear increases inconsistent with both control treatments post-fire. Compared to unburnt regions, overall diversity across all taxon groupings and habitats greatly decreased in areas exposed to extreme fire severity. Post-fire life histories are complex and species detectability is an important consideration in all post-fire sampling. We demonstrate how fire characteristics, distinct taxa, and habitat influence biodiversity, as seen in local-scale datasets. Further integration of large-scale datasets with small-scale studies will lead to a more robust understanding of fire recovery.</span></p>
SUPERYACHT_2019_Es
<p>Archimedes Yacht surface hyperspectral irradiance (Es) 2019</p> <p>Hyperspectral downwelling irradiance data collected on Archimedes Yacht in the Atlantic and Mediterranean Sea in 2019. Time stamp is in UTC. Ocean-colour sensors mounted on satellites can view the entire ocean over a period of a few days. However, to calibrate these sensors and validate the data, satellite observations must be compared with accurate and reliable in situ measurements, collected at the ocean surface. There are many regions of the ocean where these in situ measurements are rarely collected. Ocean-colour sensors can be mounted on research vessels and ships of opportunity. In this project, an ocean-colour sensor (Seabird HyperSAS Solar Tracker) was mounted on a yacht that visits remote regions of the planet where few observations have been collected. This project aims to process this data to a level for use by the scientific community for scientific applications, such as satellite validation.</p>
