%X The rates of Antarctic ice mass change have been estimated by use of the gravity solutions from GRACE level-2 RL04 for the period of January 2003 to August 2008 released by UTCSR.Because C20 of GRACE is not accurate enough,C20 from Satellite Laser Ranging(SLR) is adopted instead.The decorrelation filter technique is used for the stripe shape signal presenting in the longitude direction.Antarctic ice mass change rates are investigated again when the gravity in some one month has been chosen to get rid of,and...
