The Microwave Sounder Window Channels Brightness Temperature (BT) Climate Data Record (CDR) provides calibrated temperature data collected by the Advanced Microwave Sounding Unit - A (AMSU-A) sensor. The data are at approximately 48km global resolution with 30 observations per scan, using the “window” channels covering 23, 31, 50, and 89GHz. Data are subject to visual inspections and calibration correction verification. The final record extends from 1998–present.
