The Solar Energy Nowcasting System is capable of producing maps of spectrally-integrated irradiances of the order of 10K to 100K pixels within 1 minute and hence provide the capability needed to serve high precision solar power applications for energy planning. Surface spectra for Direct Normal Irradiance (DNI), which applies to Concentrated Solar Plants (CSP), as well as Global Horizontal Irradiance (GHI), which applies to PhotoVoltaic (PV) installations are produced at high resolution (1nm, 5 km, 15 minutes) using input data from Copernicus Atmosphere Monitoring Service (CAMS) for aerosols impact and from Spinning Enhanced Visible and InfRared Imager (SEVIRI) onboard the Meteosat Second Generation (MSG) for clouds impact.
