    The Nimbus-7 Scanning Multichannel Microwave Radiometer (SMMR) Pathfinder Daily Equal-Area Scalable Earth Grid (EASE-Grid) Brightness Temperatures (Tbs) consist of data in one of three grids: the Northern Hemisphere, Southern Hemisphere, and full global. The SMMR EASE-Grid data were derived from SMMR Pathfinder Brightness Temperatures in swath format (level 1b data).

    Coverage is global and data are available for 25 October 1978 through 20 August 1987. Resolution is 25 km for all channels (6.6, 10.7, 18, 21, and 37 GHz). Both Tb and time files are provided for a given projection in flat binary format for each day. The Tbs are provided in tenths of Kelvins and the time files are in minutes since 0:00 Coordinated Universal Time (UTC) of the date of the enclosing file.
