| Abstract: | By use of the GRACE Level-2 products,the variations of global continental water storage are deduced and in the deduction,the problems in the choice of Gaussian filter radius and the truncated degree are discussed.The computation results are good as with Gaussian smoothing radius of 800km and truncated till 20,and the variations of global continental water storage are in accord with those from CPC model in regional scale and seasonal scale. |
