NOVEL METHODOLOGY FOR APPLICATION OF ADAPTVIE SYSTEMS TECHNIQUES TO DMSP REMOTE TEMPERATURE SENSING

THE DIFFERENTIAL INVERSION TECHNIQUE DEVELOPED BY KING SHOWS EXCITING PROMISE AS A MEANS FOR OBTAINING ATMOSPHERIC TEMPERATURE PROFILES FROM UPWELLING INFRARED AND MICROWAVE RADIANCE DATA WITHOUT THE USE OF A PRIORI INFORMATION ABOUT THE STRUCTURE OF THE ATMOSPHERE. THE DEFENSE METEOROLOGICAL SATELLITE PROGRAM (DMSP) VEHICLES GENERATE A DATA SET OF UPWELLING RADIANCE SUITABLE FOR APPLICATION OF THE DIFFERENTIAL INVERSION ALGORITHM. PRACTICAL APPLICATION OF THE DIFFERENTIAL INVERSION ALGORITHM REQUIRES CAREFUL ATTENTION TO THE NUMERICAL INSTABILITIES INHERENT TO AN INVERSION TECHNIQUE BASED ON A LAPLACE TRANSFORM. NUMERICAL STUDIES BASED ON WEIGHT FUNCTIONS APPROPRIATE TO THE DMSP INSTRUMENTATION, AND MAKING USE OF SYNTHETIC RADIANCE DATA, WILL ALLOW ACCURATE DETERMINATION OF THE STABILITY OF THE DIFFERENTIAL INVERSION ALGORITHM AS APPLIED TO DMSP RADIANCE DATA. EXTENSIONS TO THE DIFFERENTIAL INVERSION ALGORITHM ARE EXPECTED TO IMPROVE ITS NUMERIC STABILITY WHILE PRESERVING ITS COMPUTATIONAL EFFICIENCY AND DESIRABLE THEORETICAL PROPERTIES. A NEW METHODOLOGY WILL BE DEVELOPED ALLOWING RAPID AND TIMELY REDUCTION OF DMSP DATA SUITABLE FOR USE IN AIR FORCE TACTICAL OPERATIONS AND OTHER APPLICATIONS. HARDWARE DEVELOPED IN THE PHASE II EFFORT FOR DELIVERY TO AFGL WILL IMPLEMENT THESE ADVANCES IN THE APPLICATION OF THE DIFFERENTIAL INVERSION ALGORITHM.
