Abstract
Satellite measurements from the Special Sensor Microwave Water Vapor Sounder are used to study the scattering effects of cirrus clouds at 183 GHz. These measurements are used in conjunction with near-coincident Geostationary Operational Environmental Satellite imager observations of visible optical depth and effective particle size. For a case of extensive cold front cirrus off the eastern US coast, the 183 GHz brightness temperature depression relative to clear skies averaged about 3 K, but sometimes exceeded 6 K. The mean effective radius of the ice particles was 141 +/- 14 micrometers . These results show promise for the estimation of ice water path form combined (Delta) Tb and effective particle size observations.
