Abstract

This paper presents the results of computer simulation associated with differential absorption lidar (DIAL) measurements of atmospheric water vapor profiles from spaceborne for the low- latitude (15N), for summer and winter in the mid-latitude (45N), and for summer and winter in the high-latitude (60N), respectively. We think that a Nd:YAG laser pumped Ti:sapphire laser is available to use with the spaceborne water vapor lidar at present. Then the water vapor absorption lines used in these calculations are in the 820 nm spectral region. The analysis suggests that the spaceborne DIAL system needs 2 or 3 pairs of the on (strong absorption) - off (weak absorption) laser lines for less than 10% profile measurements accuracy from 0 km altitude to about 10 km altitude in the mid-latitude.
