The Humidity Sounder for Brazil (HSB), a 4-channel microwave sounder provided by Brazil aimed at obtaining humidity profiles throughout the atmosphere. The HSB is the instrument in the AIRS/AMSU-A/HSB triplet that allows humidity measurements even under conditions of heavy cloudiness and haze. The HSB provided high quality data until February 2003.
- Multi-channel passive radiometer for humidity profiling, consisting of four channels: 1 at 150 GHz, 3 at 183 GHz .
- Provides atmospheric water vapor profile measurements.
- Responsible Agency: Brazilian National Institute for Space Studies.
