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.
