It measures 7 brightness temperatures in the water vapor line (22.24 GHz) and 7 in the oxygen complex (60 GHz), the former brightness temperatures are used for water vapor profiling, the latter for temperature profiling. Measurements around the water vapor line are used to derive integrated water vapor (IWV) and integrated liquid water (LWP) content.
