Abstract:Satellite laser ranging (SLR) is a well‐established geodetic technique for measuring the low‐degree time‐variable gravity field for decades. However, its application in mass change estimation is limited by low spatial resolution, even for global mean ocean mass (GMOM) change which represents one of the largest spatial scales. After successfully correcting for signal leakage, for the first time, we can infer realistic GMOM changes using SLR‐derived gravity fields up to only degree and order 5. Our leakage‐corre… Show more
