NSSDCA ID: 1972-097A-05
Mission Name: Nimbus 5The Surface Composition Mapping Radiometer (SCMR) measured (1) terrestrial radiation in the 8.3- to 9.3-micrometer and 10.2- to 11.2-micrometer intervals and (2) reflected solar radiation in the 0.8- to 1.1-micrometer range. Surface composition and sea surface temperatures could be obtained from these measurements. The SCMR had an instantaneous field of view (FOV) of 0.6 mrad, equivalent to a ground resolution of 660 m at nadir. The scan mirror rotated at 10 rps to provide scan lines 800-km wide across the spacecraft track. For a complete description, see Section 3 in "The Nimbus 5 User's Guide" (TRF B14758), available from NSSDC. The instrument began malfunctioning soon after launch. The last usable data were transmitted on January 4, 1973. A modified instrument, heat capacity mapping radiometer, was flown on the Heat Capacity Mapping Mission (HCMM) later.
