Using MODIS and TM Imageries to Assess the Effect of Cold Damage on Grain Production per Unit

Data assimilation is extensively applied in agricultural remote sensing application. However, integration of multi-temporal and high spatial resolution images with crop growth model to evaluate the effect of cold damage on paddy rice was still absent. In this paper, authors applied data assimilation combining LANDSAT/TM, a series of TERRAMODIS images with SIMRIW model to detect how cold damage affected paddy rice yield per unit in the Wuchang county, Heilongjiang province for the year 2006. In the study, MODIS images selected corresponding to a series of the key rice growth phases were utilized to retrieve daily LAI values.
