This data set of retrieved temperatures, originally supplied by experimenters in DEC format, was copied by the Nimbus Project onto magnetic tape in IBM 3081 binary integers. It consists of two kinds of data blocks: block types 7402 and 7403. For both types, the earth's surface is divided into 2.5-deg latitude by 10-deg longitude grids that extend from 50 deg S. to 67.5 deg N. Block type 7402 contains retrieved temperatures averaged over day and night at 62 pressure levels, which range from ln(P0/P)=1.4 to 13.6, with an increment of 0.2. P0 is 1000 mbar and P is the pressure in mbar. Zonal mean and climatology values are also given. Block type 7403 contains either temperatures or temperature errors averaged over day and night at 10 pressure levels: 100, 30, 10, 3, 1, 0.3, 0.1, 0.03, 0.01 and 0.003 mbar. There are some data discontinuities caused by changes in the operation modes of the instrument (CO2 channels C1 and A1). Users should refer to a tabular listing of modes for each nominal day in the "Nimbus 7 Stratospheric and Mesospheric Sounder (SAMS) Experiment Data User's Guide," which also contains an article by C.D. Rodgers et al. on the method of temperature retrieval. Each GRID-T tape contains approximately 1 calendar yr of data.
