WALI
Water vapor and Aerosol LIdar

The Water vapor and Aerosol LIdar (WALI) is a mobile, ground-based Raman lidar developed at the Laboratoire des Sciences du Climat et de l’Environnement (LSCE). It measures lidar backscatter to determine aerosol optical properties and water vapor mixing ratio profiles. WALI operates at 354.7 nm and has a temporal sampling of about 1 minute. It has a vertical resolution of about 30 meters and a field of view of about 2.3 mrad.
