Surface solar irradiance data are important for planning and estimating the production of solar power plants. Long-term high quality surface solar radiation data are needed for monitoring climate change. The broadband Surface Solar Irradiance (SSI, 0.2-4.0 micron) is derived from the OMI O2-O2 effective cloud fraction. The OMI SSI algorithm is based on the Heliosat method.
