  skos:definition """HSB is a 4-channel microwave sounder designed to obtain atmospheric humidity profiles under cloudy conditions and to detect heavy precipitation under clouds. The four HSB channels have a 1.1? beam width, resulting in a nominal horizontal spatial resolution of 13.5 km.

Three of the HSB channels make measurements on the wings of the strongly opaque water vapor resonance line at 183.3 GHz; the fourth makes measurements at 150 GHz. Successive channels have decreasing opacity and consequently their data correspond to humidities at decreasing altitudes. The four HSB channels improve the humidity profiles from AIRS/AMSU-A in the presence of liquid water.
