Abstract

A restoration of the 37, 21, 18, 10.7 and 6.6 GHz satellite imagery from the Scanning Multichannel Microwave Radiometer (SMMR) aboard Nimbus-7 to 22.2 km resolution is attempted using a deconvolution method based upon nonlinear programming. The images are deconvolved with and without the aid of prescribed constraints, which form the processed image to abide by partial a priori knowledge of the high-resolution result. The restored microwave imagery may be utilized to examine the distribution of precipitating liquid water in maritime rain systems.
