Abstract

This study presents cirrus clouds observations from the ACDL spaceborne lidar during June 2023. After calibrating the infrared channels, color ratios were derived and analyzed for their latitudinal distribution and correlation with optical properties. The mean color ratios are 0.967±0.075 (1064 to 532 nm), 0.890±0.237 (1572 to 532 nm), 0.916±0.218 (1572 to 1064 nm), respectively. The lidar ratio is 20.80±5.97sr. Results reveal that color ratios exhibit slight correlations with cirrus intensity and particle shape, and show a clear latitudinal dependence, reflecting microphysical variations of cirrus clouds.
