Abstract
A compact airborne down-looking lidar system has been developed at the U. S. Environmental Protection Agency's Environmental Monitoring Systems Laboratory in Las Vegas.1,2 This differential absorption lidar (DIAL) is designed to simultaneously measure range-resolved concentrations of ozone (O3) and sulfur dioxide (SO2) in the lower troposphere, together with an indication of the aerosol distribution. The five laser wavelengths (i.e., λI = 277 nm, λ2 = 292 nm, λ3 = 313 nm, λ4 = 319 nm, λ5 = 359 nm) are generated via Raman conversion of a focused KrF excimer laser.3
