PRELIMINARY PROCESSING OF DELTA SCANNING RADIOMETER IMAGERY

Abstract

A software package for the preliminary processing of data from the Delta scanning radiometer, developed at the Center for the Processing and Storage of Space Information (CPSSI), Russian Academy of Sciences, is described. The objectives of the preliminary processing are data reduction in conformance with EOSDIS requirements for a type 1 a information product and organization of long-term data storage in the CPSSI database in a standard HDF format and access to it via the Internet. The data processing includes filtering, correction of rotation of the polarization plane of the recorded data, calibration of data, synthesis of radiothermal images, and storage. The bulk of the processing was performed using specially developed adaptive and robust algorithms taking into account the specifics of data from the Delta radiometer. Methods and algorithms for processing are described and some examples of the processed data are presented.
