The Microwave Sounder Humidity Sounding Brightness Temperature (BT) Climate Data Record (CDR) provides BT data from the window and water vapor channel frequencies from both the Advanced Microwave Sounding Unit-B (AMSU-B) and Microwave Humidity Sounder (MHS) instruments. Channels used are 89, 150, 157, 183 +/- 1, 183 +/- 3, 183 +/- 7, 190GHz. AMSU-B data comes from NOAA-15, -16, and -17 satellites, and MHS is from NOAA-18, -19 and MetOp-A.
The data collection period of record spans from 1998–present, with monthly updates and roughly 16km spatial resolution for the entire globe, with 90 observations per scan. Quality control is applied through visual inspections and correction verification. This CDR is useful as input to hydrological products to derive global precipitation, ice water, snow cover, and snow water equivalent.
