NOAA-6, designated NOAA-A before launch, was a weather satellite operated by NOAA as part of its National Operational Environmental Satellite System. It was launched into a Sun-synchronous orbit by NASA aboard an Atlas F launch vehicle on 27 June 1979 from Vandenberg Air Force Base SLC-3W. Based on the experimental TIROS-N satellite, it performed monitoring of ice and snow cover, agriculture, oceanography, volcanism, ozone and the space environment, in addition to its regular meteorological observations.
Its instruments included the Advanced Very High Resolution Radiometer (AVHRR/1) for global cloud cover observations, the TIROS Operational Vertical Sounder (TOVS) suite for atmospheric temperature and water vapor profiling, the Space Environment Monitor (SEM) for measuring proton and electron fluxes, and the Data Collection and Platform Location System (DCPLS) for relaying data from balloons and ocean buoys. The TOVS suite consists of three subsystems: the High Resolution Infrared Radiation Sounder 2 (HIRS/2), the Stratospheric Sounding Unit (SSU), and the Microwave Sounding Unit (MSU).
The HIRS/2 instrument failed on 19 September 1983, and the spacecraft was placed in reserve in early 1984 as NOAA prioritized operations of NOAA-7 and NOAA-8. It was returned to operational status after NOAA-8 failed in June 1984, and continued to return data until its decommissioning on 31 March 1987.
