GRACE-FO Level-2 Monthly Geopotential Spherical Harmonics JPL Release 6.1 (RL06.1)
(GRACEFO_L2_JPL_MONTHLY_0061)| Version | RL06.1 |
| Processing Level | 2 |
| Start/Stop Date | 2018-May-22 to Present |
| Short Name | GRACEFO_L2_JPL_MONTHLY_0061 |
| Description | FOR EXPERT USE ONLY. This dataset contains estimates of the total month-by-month geopotential of the Earth, derived from the Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) mission measurements, produced by the NASA Jet Propulsion Laboratory (JPL). The data are provided as spherical harmonic coefficients, averaged over approximately a month. These coefficients are derived from the intersatellite range changes between the twin spacecraft of the GRACE-FO mission. This GRACE-FO RL06.1 data is an updated version of the initial GRACE-FO RL06 Level-2 data products. RL06.1 differs from RL06 only in the Level-1B accelerometer transplant data that is used for the GF2 satellite: Level-2 RL06.1 uses ACH1B RL04, which replaces ACT1B RL04 that was used for Level-2 RL06. All GRACE-FO RL06.1 Level-2 products are fully compatible with the GRACE RL06 Level-2 fields. Refer to the mission page for more information. |
