Lidar-IR radiometric cloud observation LIRADEX'98-Winter

A part of the results obtained during the winter experimental campaign 'LIRADEX'98' are presented. A vertically sounding aerosol lidar and a thermal infrared radiometer were used for joint investigation of low clouds. Both devices were placed at height of about 12 m above the ground and about 25 m apart. Data about the atmospheric parameters were obtained by parallel standard aerological observation. The experimental campaign extended two weeks during November and December, 1998. The data discussed in the presented paper are obtained on December 2, 1998.
