Differential absorption lidar sensing of ozone
The Differential Absorption Lidar (DIAL) technique has been used since the early 1970s for remote measurements of ozone (O/sub 3/) in the lower atmosphere. To investigate large-scale variations of O/sub 3/ and aerosols in the troposphere and lower stratosphere, a versatile airborne DIAL system was developed in 1980 at the NASA Langley Research Center. This DIAL system currently has the capability to measure O/sub 3/ and multiple-wavelength aerosol profiles to a range of over 8 km above and below the aircraft simultaneously. Eleven major field experiments have been conducted with the NASA air-borne DIAL system since 1980 to study the transport and chemistry related to O/sub 3/ and aerosols. This paper discusses the DIAL technique for deriving O/sub 3/ profiles from lidar measurements. The NASA airborne DIAL system is described, and examples of a broad range of O/sub 3/ and aerosol measurements are presented.
