Comparing water vapor mixing ratio profiles using lndo-Japanese Lidar in Raman mode of operation with GPS radiosondes

[ABSTRACT]We derived the height profiles of atmospheric water vapor, during nocturnal time periods, using the Inda-Japanese Lidar system augmented with Raman capability in addition to existing elastic mode of observation on experimental basis for a period of five months between January and October 2003. The derived height profiles of water vapor are corrected for aerosol and molecular transmission. During night time, the profile extends typically up to 10 km ASL with a vertical resolution of 300 m and an integration time of 15 minutes. Statistical error is typically within 5% up to 6 km of altitude and stays within 10% in 6-10 km altitude range. The height profiles of water vapor mixing ratio profiles are compared using simultaneous GPS radiosonde data. A good comparison between the lidar and radiosonde derived mixing ratio profiles were observed in the height range of observation.
