Feasibility Research on Estimating Global Paddy Yield Using Remote Sensing

Utilizing the relationship between the global NOAA data and paddy yield data during the period of 1985~1990, an estimating yield model was obtained. These models were applied to estimate paddy outputs in U. S. A. , Thailand and Viet Nam. The results are satisfactory. Furthermore, the global paddy yield during the period of 1979~1994 was simulated by using the statistical method, the fitting accuracy can reach above 98%.
