GRACE-FO Geopotential GAD Coefficients GFZ RL06

Spherical harmonic coefficients that are zero over the continents, and provide the anomalous simulated ocean bottom pressure that includes non-tidal air and water contributions elsewhere during the specified timespan. These coefficients differ from GLO (or GAC) coefficients over the ocean domain by disregarding upper air density anomalies. The anomalous signals are relative to the mean field from 2003-2014. --------------------------------------------------------------------------------------------- Version History: 19 September 2024: Release of Version 6.3. This is an update of Version 6.1 of the same data set (see changelog for details). Note that Version 6.2 was skipped to ensure consistent version numbering within the GRACE-FO Science Data System. 27 April 2022: Release of Version 6.1. This is an update of Version 6.0 of the same data set (see changelog for details). 12 June 2019: Initial release of the data (Version 6.0). All changes and updates are documented in the changelog available via the data download section (ftp://isdcftp.gfz-potsdam.de/grace-fo/Level-2/GFZ).

GRACE-FO Geopotential GAC Coefficients GFZ RL06

Spherical harmonic coefficients that represent the sum of the ATM (or GAA) and OCN (or GAB) coefficients during the specified timespan. These coefficients represent anomalous contributions of the non-tidal dynamic ocean to ocean bottom pressure, the non-tidal atmospheric surface pressure over the continents, the static contribution of atmospheric pressure to ocean bottom pressure, and the upper-air density anomalies above both the continents and the oceans. The anomalous signals are relative to the mean field from 2003-2014. --------------------------------------------------------------------------------------------- Version History: 19 September 2024: Release of Version 6.3.

GRACE-FO Geopotential GSM Coefficients GFZ RL06

Spherical harmonic coefficients representing an estimate of Earth's mean gravity field during the specified timespan derived from GRACE-FO mission measurements. These coefficients represent the full magnitude of land hydrology, ice, and solid Earth processes. Further, they represent atmospheric and oceanic processes not captured in the accompanying GAC product. --------------------------------------------------------------------------------------------- Version History: 19 September 2024: Release of Version 6.3.

GRACE-FO Geopotential GAA Coefficients GFZ RL06

Spherical harmonic coefficients that represent anomalous contributions of the non-tidal atmosphere to the Earth's mean gravity field during the specified timespan. This includes the contribution of atmospheric surface pressure over the continents, the static contribution of atmospheric pressure to ocean bottom pressure elsewhere, and the contribution of upper-air density anomalies above both the continents and the oceans.

AIUB-GRACE-FO-operational - Operational GRACE Follow-On monthly gravity field solutions - release 02

Operational GRACE Follow-On monthly gravity field solutions starting from June 2018 up to degree and order 96 computed with the Celestial Mechanics Approach at AIUB (release 02). The time series is a loose continuation of AIUB-RL02 GRACE monthly gravity field time series and is an update of the operational GRACE Follow-On monthly gravity field time series (https://doi.org/10.5880/ICGEM.2020.001) using Level-1B GRACE Follow-On data and operational accelerometer transplant data from TUG (Institute of Geodesy, TU Graz, Working Group Theoretical Geodesy and Satellite Geodesy) and updated modelling strategies concerning data screening and weighting. The time series is reprocessed starting with June 2018. The dataset is created within the framework of the G3P project (https://www.g3p.eu/), this project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 870353. The operational solution of release 02 provides a complete time series of GRACE Follow-on data derived monthly gravity field solutions, is regularly updated with new monthly solutions and features a consistent processing with an advanced noise modelling of GRACE Follow-On data. It is recommened for usage. It is strongly recommended to use release 02 and discontinue using release 01.
