Airborne DIAL remote sensing of the arctic ozone layer

摘要

A combined ozone and aerosol LIDAR has been developed at the DLR Institute of Atmospheric Physics in Oberpfaffenhofen, Germany. It is an airborne version that permits the recording of two-dimensional backscatter profiles at three wavelengths (532 nm, 354 nm, and 308 nm). From these profiles it is possible to calculate the spatial distribution of stratospheric aerosols, PSCs, and ozone. For the ozone retrieval the DIAL-principle is applied to the signals at the two shorter of the above mentioned wavelengths. The first mission with this system was performed during the EASOE campaign last winter.
