The contributions of the Principal Investigator (J. Simpson) are reported under four (4) categories: 1) AVHRR Data; 2) GOES Data; 3) System Software Design; and 4) ATSR Data. The contributions of the Associate Investigator (R. Frouin) are reported for: 1) Longwave Irradiance at the Surface; 2) Methods to Derive Surface Short-wave Irradiance; and 3) Estimating PAR at the Surface. Several papers have resulted. Abstracts for each paper and its current status (e.g., submitted, in press, published) are provided. Only representative results for papers as yet unpublished are attached.
