Assumption of similarity of ice crystals can lead to major errors in satellite observations of clouds

Assumption of similarity of ice crystals can lead to major errors in satellite observations of clouds

Assumptions used in satellite measurements that ice crystals in cirrus clouds are similar can lead to errors of up to 40% in estimates of the clouds' optical thickness and an error of -40% in estimating the effective radius of the cloud droplets.
