VALIDATION OF MIPAS WATER VAPOR PRODUCTSBY GROUND BASED MEASUREMENTS

摘要

Results of the ground based validation of MIPAS levelrn2 products, processed with software version 4.61, arernreported. Data relative to the whole altitude rangerninvestigated by MIPAS, 60-5 km, have been validatedrnby means of a microwave radiometer, for the middlernatmospheric range, and by means of three radiosoundingrnand Raman lidar systems for what concerns the upperrntroposphere and lower stratosphere (UTLS). Over 195rncases, a mean overestimation of 7-15% has beenrnobserved in the altitude range 28-55 km. On therncontrary, both lidar and radiosonde indicate anrnunderestimation of about 0.013-0.016 g/kg in MIPASrndata in the altitude range of 10-13 km. However, forrncomparison in UTLS only few data are until nowrnavailable, and a larger amount of reprocessed MIPASrndata are needed to draw more quantitative conclusion inrnthis atmospheric region.
