Restoration of Multichannel Microwave Imagery To Estimate Rainfall Rates in Hurricanes

Abstract

Multichannel microwave radiometers on the Seasat and Nimbus 7 satellites offer a quantitative method to measure rainfall amounts over the ocean. The emissivity of the ocean surface is low and varies predictably with wind speed; it thus provides a good background for observing precipitation. The theory and initial validation of this concept was given by Wilheit et al. [1]
