Abstract:Satellite laser ranging (SLR) continues to be an essential technique for estimating Earth’s low‐degree gravity field. GRACE(‐FO) does not accurately recover certain coefficients, which are needed for quantifying large‐scale mass redistribution as part of Earth’s time‐variable gravity (TVG) field. In case of an inter‐mission gap, as with GRACE and GRACE‐FO, SLR can continue to provide mass‐change measurements. The current SLR ground network consists of around 40 stations. However, these are not uniformly distri… Show more
