Paper Abstract

The visible near IR and thermal channels of ATSR-2 on the ERS-2 satellite series provide a means for retrieving radiative and physical properties of tropical cirrus clouds. Utilizing the instruments multispectral and dual-look capabilities, retrievals of optical depth, particle size and ice water path are possible, as well as cloud temperature and IR optical depth. Results using ATSR-2 data are presented for five areas in the tropics, averaged over a one month period, subject to quality controls. The retrievals were made at a 12 by 12 pixel resolution, and the output result presented at a 1 by 1 degree grid size. Preliminary comparisons with ice water path model produces from the Hadley Centre, UK have been made.
