description

''El Arenosillo'' Atmospheric Sounding Station, which belongs to the National Institute for Aerospace Technology, is located at the Atlantic Coast, next to Huelva city, in the province of Huelva of the region of Andalusia, in south-west Spain. Its surroundings correspond to the ''Doñana'' National Park, which guarantees its natural environment.
Moreover, the climate at "El Arenosillo'' is characterized by very frequent sunny conditions around 280 clear sky days a year, being a really suitable site for intercomparison campaigns.
This observatory has a long experience in radiometric studies and has hosted many calibration and intercomparison campaigns of several different UV radiometers. It also offers many calibration facilities. Thus, it has a big terrace with an open horizon.
The surroundings of the station consist of pine trees which provide a uniform albedo spatially and temporally throughout the whole year. This constant behaviour of the albedo allows the comparability of results obtained in different times of the year.
Additionally, the sounding station accounts for a well equipped laboratory where the spectral and angular characterizations of the erythemal radiometers were performed.
The main research lines of the observatory are: stratospheric ozone, solar radiation, aerosols, ozone in surface and meteorology, ionosphere and astrophysics.
