Abstract

A Raman-lidar designed for the measurement of water-vapor profiles in the atmospheric boundary-layer is presented. The light source is a frequency-doubled ruby laser; Raman returns are digitized and stored in a multichannel analyzer prior to computer processing. Profiles up to 1800 m with a vertical resolution of 30 m are obtained; the accuracy is about 15% at a height of 1000 m. The validity of the measurement is discussed, and lidar soundings are compared with co ao-18-8-1141-i001ncident meteorological radio-soundings. As an application, successive lidar profiles are used to determine the height-time structure of water-vapor, illustrating the possibilities of the Raman-lidar.
