R&D: COMPETENCES EVALUATION OF SOLAR IRRADIATION, CONCENTRATED SOLAR RADIATION AND RADIOMETERS Network measurements of solar radiation to assess the real impact of the high spatial and temporal resolution (10m &1s) in solar plants Advanced measurement station to characterize the vertical and superficial attenuation of solar radiation Measurement of concentrated solar radiation in central receiver systems Infrared reference in the 0-1700 ºC range. High solar irradiance measurement over large areas. Radiometry laboratory for high irradiance sensor calibration.
