This is an ancillary product, climatology monthly mean and standard deviation, containing a number of emissivity data. They are broadband thermal IR emissivity from the ISCCP FD radiative fluxes product the emissivity at 10.5 microns from the ISCCP IREMISS product, and the microwave emissivities at four frequencies and two polarizations from the combined analysis of SSM/I and window IR based on ISCCP DX product. The data has spatial grid cell on equal-area mapping at 1.0-degree-equivalent.
