The recent concern about food scarcity motivates the development of the present system entitled "Remote Sensing Environmental Monitor(RSEM)". The system is designed for treating carbon sequestration by vegetation, grain production, desertification of Eurasian grassland, and CDM afforestation/reforestation to a background of climate change and economic growth in rising Asian nations. The system includes a photosynthetic sterility crop yield model based on precise land use and cover(LULC) classification of crop field in two eastern Asian countries. This system also provides daily distributions of the PSN, which is the CO_2 fixation in Asian areas combined with the land-cover distribution classified from MODIS data, NDVI from SPOT VEGETATION, and meteorological re-analysis data by NCEP, U. S. A. The validation concept is based on the fact that the carbon hydrate in grains has the same chemical formula as cellulose in grain vegetation. The both photosynthesis and sterility models are calibrated by Carbon Partitioning Validation(CPV) method associated with particular rice species in Japan and China. However, more crop yield data are needed for validation of winter wheat and maize models. The mean CO_2 and carbon fixation rates in paddy areas were 25. 92(t CO_2/ha) and 5. 28(t C/ha) in Japan, respectively.

最近对粮食短缺的关注激发了名为“遥感环境监测（RSEM）”的当前系统的开发。该系统旨在处理植被、粮食生产、欧亚草原荒漠化和CDM造林/再造林的碳固存，以应对亚洲新兴国家的气候变化和经济增长。该系统包括一个光合不育作物产量模型的基础上精确的土地利用和覆盖（LULC）分类的作物领域在两个东亚国家。该系统还结合MODIS数据分类的土地覆盖分布、SPOT VEGETATION数据的NDVI以及NCEP、U. S. A.验证概念基于谷物中的碳水化合物与谷物植被中的纤维素具有相同的化学式。利用碳分配验证（CPV）方法对日本和中国的水稻品种光合作用和不育性模型进行了校正。然而，需要更多的作物产量数据来验证冬小麦和玉米模型。稻田的平均CO_2固定率和固碳率分别为25。92（t CO_2/ha）和5. 28（t C/ha）。
