Instrument:VAS
Agency: NOAA
Mission: GOES-7
Status:No longer operational
Type:Narrow-band channel IR radiometer
Description:VISSR Atmospheric Sounder., Spin scan radiometer/atmospheric sounder., 8 detectors for 1 visible channel, 6 detectors for 3 IR channels

Swath Width: N/A
Wavebands: N/A
Technology: Narrow-band channel IR radiometer
Description: Radiometer operating in MWIR and TIR with many channels of bandwidth around 1 % in absorption bands of CO2 and H2O to retrieve temperature and humidity profiles in cloud-free or partially cloudy areas. Cross-nadir scanning for vertical profiling. A few tens of channels. Spatial resolution typically 10-20 km horizontal, ~ 2 km vertical (referred to the retrieved profile). Applicable in LEO and GEO.
