Summary: | In the derivation of the vertical profile of tropospheric aerosols from lidar
data, one has to assume an appropriate value for the aerosol extinction
coefficient at a reference point, a few kilometers or more above the ground. If
the aerosol contribution at this point is not negligible compared to the
molecular contribution, the resulting aerosol extinction through the
atmosphere is affected by this boundary value. Here we propose the use of a
ground-level extinction coefficient measured by an integrating nephelometer
for the calibration of lidar data. In order to connect the ground value to the
overlap point of a vertical lidar, additional data are provided from slant path
observation using a portable lidar. |
