Abstract
WE PROPOSE A UNIFIED RETRIEVAL SYSTEM FOR ATMOSPHERIC METEOROLOGICAL PARAMETERS APPLICABLE TO THE ANALYSIS OF SENSOR PAYLOAD DATA SETS OF THE DEFENSE METEOROLOGICAL SATELLITE PROGRAM (DMSP) SPACECRAFT. THE APPROACH PROVIDES AN EFFICIENT, SELF-CONSISTENT DATA FUSION TECHNIQUE TO PROVIDE DESIRED ENVIRONMENTAL DATA RECORDS (EDRS) FROM THE ENSEMBLE OF SENSOR DATA 5D-3 SENSORS: OLS, SSM/T, SSM/T-2, AND SSM/I. IT IS EASILY EXTENDED TO ADVANCED SENSOR CONCEPTS SUCH AS SSM/IS AND IS EQUALLY VALID FOR MULTICHANNEL, HIGH SPECTRAL RESOLUTION ADVANCED SOUNDERS PROPOSED IN THE CONTEXT OF BLOCK 6. REQUIRED PARAMETERS TREATED INCLUDE TEMPERATURE AND WATER VAPOR PROFILES, SURFACE TEMPERATURE AND EMISSIVITY, CLOUD PROPERTIES, AND PRECIPITATION. THE HYBRID RETRIEVAL APPROACH EMPLOYS BOTH STATISTICAL AND PHYSICAL RETRIEVAL CONCEPTS, EXPLOITING EXISTING DMSP OPERATIONAL EXPERIENCE WITH STATISTICAL METHODS TO PROVIDE A FIRST GUESS CAPABILITY. THE FIRST GUESS IS UPGRADED, IF NECESSARY, USING A PHYSICALLY BASED, SIMULTANEOUS RETRIEVAL. REQUIRED CLOUD PROPERTIES ARE OBTAINED BY IMAGE PROCESSING HIGH SPATIAL RESOLUTION VISIBLEAND INFRARED DATA FROM A COLOCATED IMAGER. THE PROPOSED APPROACH IS OPTIMALLY DESIGNED TO SUPPORT SATELLITE DATA INGEST BY THE AFGWC GLOBAL SPECTRAL NUMERICAL WEATHER PREDICTION MODEL (GSM).
