Lidar measurements of atmospheric extinction during the MAPTIP trial

During the MAPTIP experiment, that was organized by NATO AC/243 (Panel 4)/RSG.8, the marine atmosphere was characterized, among others, with lidar (optical radar). The investigations were carried out both in horizontal planes (PPI scans), in vertical planes (RHI scans) and combinations of those two. In addition, the temporal variability of the atmosphere along one line of site was characterized by operating the lidar in a fixed direction at a sufficiently high repetition rate to follow the eddy structures. The marine aerosol layer was monitored within the surf zone and out to ranges of about 10 km. Slant path measurements provided information on the depth and structure of the mixed layer. Results obtained during this experiment are presented.
