Abstract
We mainly presented the modification of the cloud parameters in both temporal and spatial dimensions.The modification leads to a new drought monitoring model with a stable performance to variation of time and space of remote sensing data.This modification function was applied to regulate the 3 cloud impaction functions.Finally,we modified the new drought inspection model by evaluating different weights to the 3 cloud impaction functions.Meanwhile,we applied this new model to the FY-2C data covering the whole China.Compared with the traditional monitoring algorithms,the new model is proved to be capable of providing a more accurate and reliable result in large scale of time and space.
