Dual Lidar Observations at 10.6 μm and 532 nm for Retrieving Semitransparent Cirrus Cloud Properties

Source: Journal of Applied Meteorology and Climatology:;2006:;volume( 045 ):;issue: 004:;page 537

Author(s): Chiriaco, M.; Chepfer, H.; Noel, V.; Haeffelin, M.; Drobinski, P.

Publisher: American Meteorological Society

Abstract: To improve the estimation of the infrared radiances in cirrus clouds, one needs to consider the vertical inhomogeneities of the cloud properties. The position of the maximum of absorption within an ice cloud is potentially ...
