The Solar Radiation Group of the University of Valencia (GRSV) participates in the ARCSIX project, Arctic Radiation Cloud Aerosol Surface Interaction Experiment (https://espo.nasa.gov/arcsix) led by NASA.
The ground-based observations are carried out in collaboration with different Italian institutions, Istituto Nazionale di Geofisica e Volcanologia (INGV) and the Agenzia nazionale per le nuove tecnologie, l'energia e lo sviluppo economico sostenibile (ENEA), in charge of the THAOO observatory.
The Solar Radiation Group of the University of Valencia (GRSV) participates in the ARCSIX project, Arctic Radiation Cloud Aerosol Surface Interaction Experiment (https://espo.nasa.gov/arcsix) led by NASA.
The objective of ARCSIX is to quantify the contribution of surface properties, clouds, aerosols and precipitation in the radiative budget and ice-melting in the Arctic summer.
For this, an international and multidisciplinary experiment has been designed in which the measurements made from two aircraft instrumented for atmospheric observation will serve as a link between the simultaneous satellite and ground-based observations. The experiment will be carried out in Greenland through two intensive measurement campaigns, in May and July 2024, and continuous ground-based monitoring throughout the summer of 2024.
José Luis Gómez Amo, member of the GRSV, will travel to the Thule High Arctic Atmospheric Observatory (THAAO, http://www.thuleatmos-it.it/index.php) in Greenland (76.5 ºN, -68.7. W, 225 m a.s.l.) for the installation and commissioning of a zenith observation spectrometer (TWST) and a all-sky camera (SONA). This instrumentation will be controlled by the GRSV and will allow the optical properties of aerosols and clouds to be monitored from the surface, as well as solar radiation, throughout the summer of 2024 (May-September). The ground-based observations are carried out in collaboration with different Italian institutions, Istituto Nazionale di Geofisica e Volcanologia (INGV) and the Agenzia nazionale per le nuove tecnologie, l'energia e lo sviluppo economico sostenibile (ENEA), in charge of the THAOO observatory.
The GRSV contribution to ARCSIX is linked to the international activities of the PELICAN project (A ground-based remote sensing strategy to explore aErosol cLoud InteraCtions and rAdiative forcing, PID2021-123881OB-I00) funded by the Ministry of Science and Innovation for the study of the interaction effects between clouds and aerosols on terrestrial radiative forcing.
