Abstract
System definition and performance calculations are presented for a variable-wavelength solar-blind Raman lidar capable of remotely measuring profiles of atmospheric water-vapor concentration and temperature. A figure of merit is defined which is related to the wavelength dependent SNR. It is shown that the figure of merit for a particular output wavelength depends critically on the instantaneous total ozone overburden as well as the ozone content from the earth’s surface up to a maximum measurement altitude. Figures of merit for water-vapor and temperature profile measurements are presented. Best performance output wavelengths are given, and total output energies required to yield prespecified accuracies are computed.
