OUR MAIN TASK OVER THE NEXT TWO YEARS WILL BE TO MONITOR IMPACTS TO OUR PRODUCTS DUE TO ORBIT CHANGES INSTRUMENT AGING AND CHANGES IN UPSTREAM PRODUCTS ( DAILY SURFACE REFLECTANCE AND BRIGHTNESS TEMPERATURE) AND TO INFORM USERS OF ANY PROBLEMS AFFECTING PRODUCT ACCURACY AND USABILITY. MODIS VCF (MOD44B) DEPENDS ON A 16-DAY COMPOSITE (MOD44C) FINE-TUNED FOR MOD44B INPUT. WE WILL MAINTAIN THIS INTERMEDIATE PRODUCT AS WELL AND CAN UPDATE THE COMPOSITING RULES AS NECESSARY. THROUGHOUT THIS MAINTENANCE PERIOD WE WILL CONTINUE TO FULLY PARTICIPATE IN THE MODIS SCIENCE TEAM AND THE SCIENCE TEAM MEETINGS.
