Abstract

This paper discusses recent measurements of water-vapor profiles in the lower troposphere which have been made with the NASA Langley Airborne Differential Absorption Lidar (DIAL) System. Measurements were made in the vicinity of NASA Langley Research Center and compared with in-situ data obtained from a locally launched radiosonde and with DIAL water-vapor measurement simulations. Remote measurements of water-vapor profiles such as those described in this paper are important for investigations of latent heat flux, air-mass modification over bodies of water, water-vapor transport into the stratosphere, and initialization conditions for weather forecast models.
