摘要：
Based on the dynamic orbit determination model of PANDA, the temporal gravity models named WHUTM have been computed with coefficients truncated up to 60 degree from March 2006 to February 2007, using the two-step variational approach and parallel programming. By analyzing the water storage variation of Amazon and other 5 river basin, a comparison with other GRACE solutions is made. The results has showed that WHUTM can reflect the seasonal change of water storage variation in all selected river basin, and it also can be observed that WHUTM has a reasonable agreement with other GRACE solutions, and is particularly closed to the JPL and DEOS models.
