The Solar Radiation group of Valencia (GRSV/ GIUV2013-074) is a reference group on the two lines in which it works, atmospheric aerosols and UV solar radiation.
 

Currently, the Solar Radiation group participates in the international aerosol measurement network AErosol RObotic NETwork (AERONET, https://aeronet.gsfc.nasa.gov/). The AERONET program is a federation of ground-based aerosol networks established by NASA and PHOTONS (PHOtométrie pour le Traitement Opérationnel de Normalization Satellitaire; Univ. De Lille 1, CNES and CNRS-INSU) and extended through other networks such as RIMA (Red Ibérica de Medida de Aerosols), AeroSpan, AEROCAN and CARSNET and where national agencies, institutes and universities are collaborators. The program provides a public domain database of aerosol optical, microphysical, and radiative properties for aerosol research and characterization, satellite validation, and synergy with other databases. The Solar Radiation group has two stations (Burjassot and Aras de los Olmos) that are part of this AERONET network and actively collaborate with other Spanish stations of the RIMA Network in its operation. In addition, the GRSV also coordinates the European Skynet Radiometers network (ESR, http://www.euroskyrad.net/) together with the Institute of Atmospheric and Climate Sciences of the Italian National Research Council (CNR). Various European Universities/Meteorological Services from Italy, Germany, United Kingdom, Chile, as well as the US NREL.
 

In addition, the GRSV are Associated Partner to the ACTRIS2 network (Aerosols, Clouds, and Trace gases Research InfraStructure Network) (www.actris.eu), a European research infrastructure (RI) financed within the H2020 program in the context of Climate Change . The network has been accepted in the roadmap of ESFRI (The European Strategy Forum on Research Infrastructure) in 2016. This means that the ACTRIS network is configured as a pan-European research infrastructure that will be consolidated and operational throughout the next ten years. The ACTRIS project has the participation of 28 European organizations and its objective is to establish a network of stable scientific infrastructures equipped with advanced instrumentation for the measurement of atmospheric aerosols, gases and clouds.
 

They also participate in the ACTRIS-ESPAÑA thematic network, which develops research on the direct and indirect effects of aerosols and clouds, as well as on the processes associated with atmospheric pollutants that are involved in the deterioration of air quality that cause negative effects. adverse effects on health and ecosystems. Likewise, ACTRIS-ESPAÑA will contribute to developing sustainable solutions that respond to environmental challenges, thus perfectly integrating into the general objectives of ACTRIS. In this network, work is being done to transform the Agreement of Intent (Memorandum of Understanding) that exists between the participants in this network and with AEMET, which participates in it as an external entity, into a Joint Research Unit (JRU), operational at European, through an agreement between the entities adapted to Law 40/2015 on the Legal Regime of the Public Sector.
At the national level, it has also been part of the Network of Excellence  for the study of aerosols, clouds and trace gases in Spain, led by the University of Granada and financed by the Ministry of Economy and Competitiveness, and of which are part of the Polytechnic University of Catalonia (UPC), University of Valencia (UV), University of Valladolid (UVa), Center for Energy, Environmental and Technological Research (CIEMAT), Institute of Environmental Assessment and Water Research (IDAEA/CSIC ), Barcelona Supercomputing Center (BSC), and National Institute of Aerospace Technology (INTA), Miguel Hernández University of Elche.
