Simultaneous measurements of water vapor profiles from airborne MIRand LASE

摘要

A NASA ER-2 aircraft flight with both Millimeter-wave Imagingradiometer (MIR) and Lidar Atmospheric Sensing Experiment (LASE) wasmade over ocean areas in the eastern United States on September 25,1995. The water vapor profiles derived from both instruments under bothclear and cloudy conditions are compared. It is shown that goodagreement is found between the MIR-derived and the LASE-measured watervapor profiles over the areas of clear-sky conditions. In the cloudyareas, the MIR-retrieved values at the altitudes of the cloud layers andbelow are generally higher than those measured by the LASE
