Abstract :
A second Antarctic Miniature Lidar instrument (Ant Lidar II) has been assembled, tested, and deployed to the NOAA Clean Air Facility (CAF) at the Amundsen-Scott South Pole Station. This instrument deployed in February of this year replaces the first Antarctic Lidar (Ant Lidar I) which operated at the South Pole Station from February to July 1995. The new lidar, as in the first instrument, uses redundant commercially available, single element diode lasers, a 20 cm Schmidt-Cassegrain telescope, and a silicon avalanche photodiode (APD) operated in the photon counting mode. The authors present measurements from the Ant Lidar I instrument as well as the design of the Ant Lidar II instrument and measurements made both prior to and following its installation at the NOAA CAF in February, 1996
