Tellus Level-4 Greenland Mass Anomaly Time Series from JPL GRACE/GRACE-FO Mascon CRI Filtered Release 06 version 02

(GREENLAND_MASS_TELLUS_MASCON_CRI_TIME_SERIES_RL06_V2)
Version2
Processing Level4
Start/Stop Date2002-Apr-01 to Present
Short NameGREENLAND_MASS_TELLUS_MASCON_CRI_TIME_SERIES_RL06_V2
DescriptionThis dataset is a time series of mass variability averaged over all of Greenland. It provides the ice mass changes of Greenland over time. The mass variability are derived from JPL GRACE Mascon Ocean, Ice, and Hydrology Equivalent Water Height RL06Mv2 CRI Filtered Version 2, which can be found at https://podaac.jpl.nasa.gov/dataset/TELLUS_GRAC-GRFO_MASCON_CRI_GRID_RL06_V2. A more detailed description on the Mascon solution, including the mathematical derivation, implementation of geophysical constraints, and solution validation, please see Watkins et al., 2015, doi: 10.1002/2014JB011547. The mass variability are provided as an ASCII table.
