Satellite‐Based Identification of Large Anthropogenic NMVOC Emission Sources

Journal of Geophysical Research: Atmospheres, Volume 129, Issue 22, 28 November 2024.
Abstract Nonmethane volatile organic compounds (NMVOCs) emitted in excess from anthropogenic sources significantly contribute to the formation of harmful pollutants, thereby degrading air quality. While satellite measurements have become valuable tools for tracking anthropogenic emitters, they have primarily targeted inorganic species and methane (CH4 $

Updated OMI Glyoxal Column Measurements Using Collection 4 Level 1B Radiances

Earth and Space Science, Volume 11, Issue 9, September 2024.
Abstract This study presents new glyoxal (CHOCHO) products from the Ozone Monitoring Instrument (OMI) by utilizing updated level 1B irradiance/radiance data (Collection 4) and an updated glyoxal retrieval algorithm. The adoption of Collection 4 contributes to the reduction of artificial signals in differential glyoxal slant column densities (dSCDs) and

Del lat. COCCUM, COCEUS y COCCINUS al esp. coco, cocho, cochino y cochinilla

Revista de Filología Española, 2013
El sustantivo coccum, con un gran empleo en latín, ha tenido una numerosa descendencia en romance. De él proceden coco y coca; pero, dada su complejidad polisémica y homonímica, falta saber en qué medida. Según nuestra propuesta, de los adjetivos cocceus

Fish diversity of Colombian Andes‐Amazon streams at the end of conflict is a reference for conservation before increased land use

Ecology and Evolution, Volume 14, Issue 3, March 2024.
Aquatic ecosystems in the Andes‐Amazon transition zone of Colombia are now at high risk due to expanded human activities after peace agreements in 2016 ended armed conflict. Fish communities exhibit altitudinal biodiversity gradients that are consistent in space and time, and that need to be accounted for conservation and management considerations. Our
