GOES-East Surface Solar Irradiance

Operational Near real time product

Estimation of the solar irradiance reaching the Earth surface derived from the 0.6 µm visible channel of the imager on board the geostationary satellite GOES. Algorithm is a physical parametrization applied separately to every pixel of a satellite image to derive an instantaneous field of the Surface Solar Irradiance. The hourly product is interpolated at rounded UT hours, by a pixel dependant temporal interpolation between two consecutive satellite images.
The value in the daily product is the integration of all the hourly values in the UT day.
The product is remapped onto a 0.05° regular grid and expressed in W/m2.
