Description
Summary:This progress report presents the results obtained to date by the Naval Research Laboratory from their participation in the Joint-Services Microwave Definition Study. This is a joint Navy/Air Force effort to develop a microwave scanning system for the Defense Meteorological Satellite Program (DMSP) to provide all weather, global measurements of the sea surface winds, temperature and ice cover, precipitation over land and sea, and atmospheric liquid water and water vapor to support Department of Defense world-wide military operations. Three tasks are addressed. Task I is a sensor performance analysis, system trade-off study and algorithm development program utilizing a theoretical/empirical environmental model and a statistical description of the environmental parameters. Results are presented of a comparison of selected candidate sensor system with regard to their relative accuracy in measuring the desired surface and atmospheric environmental properties. Task II is to develop a complete set of statistics necessary for Task I. It consists of deriving the means and covariance matrix for all of the desired environmental parameters. In all twelve matrices are being computed corresponding to arctic, temperate and tropic latitudes under spring, summer, fall and winter conditions. Task III is to conduct a flight program using the NRL RP3-A aircraft and sensor complement to obtain microwave measurements of marine wind speed, atmospheric liquid water and water vapor, and precipitation over land and ocean to evaluate sensor performance models and data reduction algorithms. The results of the flight program in September 1977 to measure precipitation over land and sea are presented.
