The Nimbus-6 satellite was successfully launched on June 12, 1975. The Nimbus-6 Scanning Microwave Spectrometer (SCAMS) experiment was follow on to the successful Nimbus-E Microwave Scanner (NEMS) flown on Nimbus-5.
SCAMS continuously monitored emitted microwave radiation at frequencies of 22.235, 31.65, 52.85, 53.85 and 55.45 GHz. The instrument scanned plus or minus 45 deg normal to the orbital plane with a 10-deg field of view. The swath width is about 2400 km, with a spatial resolution of 145 km at nadir to about 330 km at the scan edges. Measurement objectives include:
Atmospheric temperature profiles - 52.85, 53.85 and 55.45 GHz (O2 absorption band)
Water vapor and cloud liquid content - 22.235 and 31.65 GHz (H2O bands)
