Tellus Level-4 Antarctica Mass Anomaly Time Series from JPL GRACE/GRACE-FO Mascon CRI Filtered Release 06 version 02
(ANTARCTICA_MASS_TELLUS_MASCON_CRI_TIME_SERIES_RL06_V2)Version | 2 |
Processing Level | 4 |
Start/Stop Date | 2002-Apr-01 to Present |
Short Name | ANTARCTICA_MASS_TELLUS_MASCON_CRI_TIME_SERIES_RL06_V2 |
Description | This dataset is a time series of mass variability averaged over all of Antarctica. It provides the ice mass changes of Antarctica over time. The mass variability are derived from JPL GRACE Mascon Ocean, Ice, and Hydrology Equivalent Water Height RL06Mv02 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. |
