Las l\u00edneas de investigaci\u00f3n se centran en la caracterizaci\u00f3n de la ionosfera y de la radiaci\u00f3n solar, el estudio de la variabilidad de la composici\u00f3n qu\u00edmica de la atm\u00f3sfera con especial \u00e9nfasis en los gases de efecto invernadero, gases reactivos, ozono estratosf\u00e9rico, y diversas propiedades microf\u00edsicas, \u00f3pticas y qu\u00edmicas de las part\u00edculas atmosf\u00e9ricas. Adem\u00e1s, proporciona servicio de acceso a los investigadores nacionales e internacionales que buscan respuesta a los retos que plantean el clima y la calidad del aire en el Sistema Tierra desde una perspectiva global. Las principales singularidades que tiene la ESAt-El Arenosillo son: un emplazamiento \u00fanico para realizar observaci\u00f3n e investigaci\u00f3n atmosf\u00e9rica desde la baja troposfera hasta la ionosfera, las distintas instalaciones disponibles para el usuario como son el Laboratorio In-situ de Calidad del Aire y el Clima (ISLA), el Laboratorio de Calibraci\u00f3n Radiom\u00e9trica, la plataforma de intercomparaci\u00f3n, la torre de 100 m, y distintas plataformas a\u00e9reas pilotadas remotamente, la variedad en el equipamiento y conocimiento cient\u00edfico que a\u00fana t\u00e9cnicas de medida como las in-situ en superficie y las t\u00e9cnicas de teledetecci\u00f3n pasiva y activa, y operan bajo redes de monitorizaci\u00f3n consolidadas como NASA\/AERONET, NASA\/MPLNet, NOAA\/FAN, EUBREWNET, etc. una red de usuarios consolidada que acceden a sus datos y a su infraestructura de forma habitual, red que se encuentra siempre en continuo crecimiento, participaci\u00f3n en redes ERIC (European Research Infrastructure Consortia) del programa ESFRI (European Strategy Forum on Research Infrastructures) como ACTRIS (Aerosol, Clouds and Trace Gases Research Infrastructure) e ICOS (Integrated Carbon Observation System), participaci\u00f3n como plataforma de acceso transnacional en proyectos financiados por H2020-INFRAIA y HORIZON-INFRA como son ATMO-ACCESS (Solutions for Sustainable Access to Atmospheric Research Facilities, Grant Agreement 101008004, https:\/\/www.atmo-access.eu) e IRISCC (Integrated Research Infrastructure Services for Climate Change Risks, Grant Agreement 101131261, https:\/\/www.iriscc.eu ).\u00a0<\/p>","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"elementor_header_footer","meta":{"neve_meta_sidebar":"","neve_meta_container":"","neve_meta_enable_content_width":"","neve_meta_content_width":0,"neve_meta_title_alignment":"","neve_meta_author_avatar":"","neve_post_elements_order":"","neve_meta_disable_header":"","neve_meta_disable_footer":"","neve_meta_disable_title":"","neve_meta_reading_time":"","footnotes":""},"class_list":["post-4250","page","type-page","status-publish","hentry"],"publishpress_future_action":{"enabled":false,"date":"2026-04-14 03:19:40","action":"change-status","newStatus":"draft","terms":[],"taxonomy":""},"publishpress_future_workflow_manual_trigger":{"enabledWorkflows":[]},"_links":{"self":[{"href":"https:\/\/actris.es\/en\/wp-json\/wp\/v2\/pages\/4250","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/actris.es\/en\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/actris.es\/en\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/actris.es\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/actris.es\/en\/wp-json\/wp\/v2\/comments?post=4250"}],"version-history":[{"count":24,"href":"https:\/\/actris.es\/en\/wp-json\/wp\/v2\/pages\/4250\/revisions"}],"predecessor-version":[{"id":4338,"href":"https:\/\/actris.es\/en\/wp-json\/wp\/v2\/pages\/4250\/revisions\/4338"}],"wp:attachment":[{"href":"https:\/\/actris.es\/en\/wp-json\/wp\/v2\/media?parent=4250"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
