Abstract

Thermal-infrared emission spectra from cirrus clouds taken with a unique prism spectrograph are combined with K_a-band radar reflectivity measurements to obtain mass concentration and size information on the cirrus ice crystals. A two-stream radiation transfer model utilizing Mie scattering theory was used to infer the averaged effective ice sphere diameter which, for the cirrus studied, was near 50 μm
