Data are available in the Northern Hemisphere, Southern Hemisphere, Temperate, and Mid-Latitude (subset of Global) EASE-Grid 2.0 projections and on the 3 km, 3.125 km, 9 km, 25 km, and 36 km resolution grids. This is a companion product for the Calibrated Enhanced-Resolution Passive Microwave Daily EASE-Grid 2.0 Brightness Temperature ESDR data set. The same SIR technique is applied to derive brightness temperatures from the SMMR, AMSR-E, and SSM/I-SSMIS sensors as for that data set.
