Abstract:
A polarization diversity elastic backscatter lidar has been deployed on the isle of Palau (7°28′N 134°33′E) in Fabruary-March 2016, in the framework of the EU fundeed project Stratoclim. The lidar operated for 8 hours at nighttime from 15 February to 25 March, collecting atmospheric profiles of aerosol and clouds. The aerosol profile from the boundary layer to 25 km could be measured and is hereby presented, together with temperature profiles from operational radiosondes. Thin cirrus clouds were often detected at the local tropopause and statistics of their occurrence, together with their correlation with tropopause morphology and temperatures will be discussed.
