VALIDATION OF MIPAS WATER VAPOR PRODUCTS BY GROUND BASED MEASUREMENTS

摘要

Results of the ground based validation of MIPAS level 2 products, processed with software version 4.61, are reported. Data relative to the whole altitude range investigated by MIPAS, 60-5 km, have been validated by means of a microwave radiometer, for the middle atmospheric range, and by means of three radiosounding and Raman lidar systems for what concerns the upper troposphere and lower stratosphere (UTLS). Over 195 cases, a mean overestimation of 7-15% has been observed in the altitude range 28-55 km. On the contrary, both lidar and radiosonde indicate an underestimation of about 0.013-0.016 g/kg in MIPAS data in the altitude range of 10-13 km. However, for comparison in UTLS only few data are until now available, and a larger amount of reprocessed MIPAS data are needed to draw more quantitative conclusion in this atmospheric region.
