Abstract :
Nadir-looking microwave radiometers are flown on different altimeter missions to correct the altimeter range for water vapor and cloud liquid water path delay in troposphere. Actually four sensors, TOPEX, JASON-1, ERS-2, and ENVISAT microwave radiometers (MWR) provide continuous measurement and the aim of this paper is to compare their measured brightness temperatures over the same hot reference continental area.
