|Description||The JPL monthly ocean mass grids contain ocean water mass anomaly given as equivalent water thickness derived from GRACE time-variable gravity observations during the specified timespan in ASCII/netCDF/GeoTIFF formats. The Equivalent water thickness is used to represent the water mass so it can be comparable to sea level anomalies due to water mass changes. The time coverage for the monthly grids are determined by GRACE months ( https://podaac-tools.jpl.nasa.gov/drive/files/allData/tellus/L3/docs/GraceMonths.html ). These mass grids represent the full magnitude of ocean processes, including the global mean ocean bottom pressure change (ocean mass and mean atmosphere mass over the global oceans). The Level-2 GAD product has been added back, a glacial isostatic adjustment correction has been applied, and standard corrections for geocenter (degree-1) and C20 (degree-20) are incorporated. Post-processing filters have been applied to reduce correlated errors. From the RL06 version, all GRACE products in the ASCII format have adopted the YAML encoding header, which is in compliance with the PO.DAAC metadata best practice. This version has been superseded by v02. The v02 has resolved a processing inconsistency issue in the v01 files for both GRACE and GRACE-FO. This inconsistency resulted in erroneous leakage corrections, in particular near GIA-affected regions.|
