Abstract :
This paper outlines the results of two recent efforts to use the NPOESS Aircraft Sounder Testbed-Microwave (NAST-M) airborne sensor to directly validate the microwave radiometers on a number of operational satellites. Radiance differences between the NAST-M sensor and the Advanced Microwave Sounding Unit (AMSU) and the Microwave Humidity Sensor (MHS) were found to be less than 1 K for most channels. Comparison results for ocean underflights of the Aqua, NOAA, and MetOp-A satellites are shown.
