Título : Taller CAMS NCP [Vídeo] Autor : Agencia Estatal de Meteorología (España) Resumen : El 16 de abril, el Barcelona Supercomputing Center - Centro Nacional de Supercomputación (BSC-CNS) y la Agencia Estatal de Meteorología (AEMET) organizaron un taller de usuarios en el marco del Programa Nacional de Colaboración del Servicio de Vigilancia de la Atmósfera de Copernicus (CAMS NCP). El objetivo del proyecto es impulsar el uso de los productos de CAMS para maximizar su utilidad en la toma de decisiones estratégicas sobre la calidad del aire. El evento reunió a más de 70 investigadores, gestores ambientales y responsables de la toma de decisiones, y contó con ponencias del European Centre for Medium-Range Weather Forecasts (ECMWF), del Ministerio para la Transición Ecológica y el Reto Demográfico (MITECO) y del Centro de Investigaciones Energéticas, Medioambientales y Tecnológicas (CIEMAT). Descripción : Vídeo que recoge el Taller de usuarios, celebrado el 16 de abril de 2026, en el marco del Programa Nacional de Colaboración del Servicio de Monitoreo de la Atmósfera de @CopernicusEU (CAMS) en la sede de AEMET.

Título : Disentangling the drivers of soil CO2 ventilation in a Mediterranean dryland using in situ and remote sensing techniques Autor : Abril Gago, Jesús; Tovar, Irene; Echeverría, María Teresa; Andújar Maqueda, Juana; Ortiz Amezcua, Pablo; Cabrera Carrillo, Germán; Serrano Ortiz, Penélope; Domingo, Francisco; Alados Arboledas, Lucas; Kowalski, Andrew S.; Sánchez Cañete, Enrique P.; Guerrero-Rascado, Juan Luis Resumen : Subterranean CO2 concentrations are driven by complex interactions between biological and physical processes. In semiarid ecosystems, atmospheric processes can play a relevant role in modulating soil CO2 storage and release. In the current study, a multi-instrumental dataset, collected in a Mediterranean shrubland in southern Spain, was analyzed, and the main atmospheric drivers controlling soil CO2 and radon (Rn) dynamics were investigated. Based on a precise methodology, 10 significant ventilation events were detected, and the Spearman correlation coefficients between the soil CO2 and Rn concentrations and the different atmospheric variables were calculated. The results identified surface atmospheric pressure as the most consistent and independent driver across the events, exhibiting strong negative correlations with the subterranean CO2 and Rn concentrations. Surface-level friction velocity (u∗), boundary-layer turbulent kinetic energy dissipation rate (ϵ) and wind shear (sh) showed significant positive correlations. However, their independence was not consistent when compared with diluting ventilation events, when u∗ was more relevant, with enriching ventilation periods, that were more influenced by boundary-layer ϵ and sh. In contrast, at lower altitudes ϵ, sh, atmospheric boundary layer height and mixing layer height were less strongly correlated with soil CO2 and Rn concentration changes. These findings provide new insights into the mechanisms that promote soil-atmosphere transport in drylands, especially those regarding the carbon cycle, and highlight the need to incorporate such mechanisms into Earth system models to improve carbon cycle predictions under future climate scenarios.

Título : Volcanic plume height during the 2021 Tajogaite eruption (La Palma) from two complementary monitoring methods – implications for satellite-based products Autor : Barreto Velasco, África; Quirós, Francisco; García Rodríguez, Omaira Elena; Pereda de Pablo, Jorge; González-Fernández, Daniel; Bedoya Velásquez, Andrés Esteban; Sicard, Michaël; Córdoba-Jabonero, Carmen; Iarlori, Marco; Rizi, Vicenzo; Krotkov, Nickolay; Carn, Simon; Roininen, Reijo; Molina Arias, Antonio J.; Almansa Rodríguez, Antonio Fernando; Álvarez-Losada, Óscar; Aramo, Carla; Bustos Seguela, Juan José de; Ceolato, Romain; Comerón, Adolfo; Felpeto, Alicia; García Cabrera, Rosa Delia; González-Sicilia, Pablo; González Ramos, Yenny; Hedelt, Pascal; Hernández Martínez de la Peña, Miguel; López Cayuela, María Ángeles; Loyola, Diego; Meletlidis, Stavros; Muñoz Porcar, Constantino; Pietropaolo, Ermanno; Ramos López, Ramón; Rodríguez Gómez, Alejandro; Román, Roberto; Romero Campos, Pedro Miguel; Stuefer, Martin; Toledano, Carlos; Welton, Ellsworth J. Resumen : Volcanic emissions from the Tajogaite volcano, located on the Cumbre Vieja edifice on the island of La Palma (Canary Islands, Spain), caused significant public health and aviation disruptions throughout the eruption (19 September–13 December 2021, officially declared over on 25 December). Nonetheless, it is considered the most significant volcanic event in Europe over the past 75 years due to the substantial amount of SO2 released into the atmosphere. The Instituto Geográfico Nacional (IGN), the authority responsible for volcano surveillance in Spain, implemented extensive operational monitoring to track volcanic activity and to provide a robust estimation of the volcanic plume height using a video-surveillance network. In parallel, the State Meteorological Agency of Spain (AEMET), in partnership with other Spanish ACTRIS (Aerosol, Clouds, and Trace Gases Research Infrastructure) members and collaborating institutions, conducted an unprecedented instrumental deployment to evaluate the impacts of this volcanic event on atmospheric composition. This effort included a network of aerosol profilers surrounding the volcano. A total of four profiling instruments were installed on La Palma: one MPL-4B lidar and three ceilometers. Additionally, a pre-existing Raman lidar on the island contributed valuable data to this study. These efforts are undertaken due to the importance of monitoring volcanic plume height in terms of air quality (necessary for the implementation of effective civil protection policies), volcanic activity surveillance (for tracking and forecasting eruptive behaviour), and, from a scientific perspective, for improving our understanding of the climatic and radiative impacts of this type of aerosol.
