This dataset contains the Global Mean Ocean Mass trend generated from the GRACE JPL RL05M ( ftp://podaac.jpl.nasa.gov/allData/tellus/L3/mascon/RL05/JPL/CRI/ ). The time series is a 1-dimensional time series of globally averaged ocean water mass from GRACE expressed in equivalent water height (cm). Seasonal variations have been removed. It starts in May 2002 to present, with a lag of up to 4 months. These data are available in ASCII (Reference: Watkins et al., 2015, doi: 10.1002/2014JB011547.).
