Abstract
A RESEARCH PROGRAM TO PROVIDE SIMULATION MODELS APPLICABLE TO THE DESIGN SPECIFICATION OF A MICROWAVE MOISTURE SOUNDER OPERATING AT 183 GHZ IS DESCRIBED. THE DESIGN SPECIFICATION PROCESS CONSISTS OF INSTRUMENT RESPONSE SIMULATION, SENSITIVITY ANALYSES, AND MOISTURE RETRIEVAL PERFORMANCE ASSESSMENT. THE OBJECTIVE OF THE INITIAL EFFORT IS TO DEVELOP COMPUTER ALGORITHMS CAPABLE OF TREATING THE RESPONSE OF A MULTI-FREQUENCY RADIOMETER TO REALISTIC VARIATIONS IN RELEVANT METEOROLOGICAL VARIABLES POTENTIALLY AFFECTING ITS OPERATIONAL PERFORMANCE. THESE INCLUDE TEMPERATURE AND MOISTURE PROFILES, SURFACE EMMISSIVITY, CLOUDS, AND PRECIPITATION. A MULTICOMPONENT APPROACH BASED ON RADIATIVE TRANSFER THEORY AND SUPPORT BY METEOROLOGICAL AND SPECTRAL DATA IS PROPOSED. THE MODELS WILL BE TESTED AND VERIFIED AND PRELIMINARY RECOMMENDATIONS WILL BE TENDERED CONCERNING POTENTIAL CLOUD DEGRADATION OF ALL WEATHER PERFORMANCE BASED ON LIMITED SENSITIVITY TESTS.
