A pulsed CO2 lidar was used to measure atmospheric extinction and backscattering at 10 µm during different types of weather. Comparison was made between extinction evaluated from the atmospheric echo and from measurements against calibrated plates. Vertical soundings showed that the backscatter could drop a factor of 10 during the first kilometer. The implications of extinction and backscatter to the performance of single-ended CO2 lidars for atmospheric sensing are discussed.
