A SAM 400-series sensor has been deployed and installed In the province of Almeria in southeast Spain. This site is known as the Plataforma Solar de Almeria (PSA) and lies on the edge of Tabernas Desert. It extends over 250 acres and has been used for the testing and optimization of a variety of high-temperature solar technologies since 1980.
Among the various instruments are more than 20,000 square meters of mirrors of various shapes that are used to concentrate the direct solar radiation to generate high and extremely high temperatures. These facilities make up the largest test center in Europe for concentrating high-temperature solar technologies, and is one that leads the world in its variety.
The SAM sensor adds important information about the direct solar radiation that reaches the ground. It measures both the radiation that comes from the solar disk as well as from the area around the Sun (the aureole). This latter component provides extremely useful information from the region of sky that extends from about 1/2-degree to 8-degrees from the Sun, which cannot be measured by any other conventional sensor.
The SAM sensor was purchased by the Institute of Solar Research of the German Aerospace Centre (DLR). http://www.dlr.de/sf/en/desktopdefault.aspx/
