Gravitational mass balance of Greenland 2003 to present v3.0
Greenland mass balance (GMB) product for the Greenland Ice Sheet from GRACE(-FO) satellite gravimetry (CSR RL06.2) by DTU Space, computed with the mass point inversion method.
The GMB are derived by DTU Space within the ESA CCI GIS project and they are provided as temporal mass changes and 5-yearly gridded mass trends in the file:
ESACCI-GIS-L3-GMB-DTU-2024-fv3.0.nc
The GMB temporal mass changes are also provided in ascii format (in the folder time_series).
- GIS00_grace.dat : all GIS
- GIS01_grace.dat : Basin 1
- GIS02_grace.dat : Basin 2
- GIS03_grace.dat : Basin 3
- GIS04_grace.dat : Basin 4
- GIS05_grace.dat : Basin 5
- GIS06_grace.dat : Basin 6
- GIS07_grace.dat : Basin 7
- GIS08_grace.dat : Basin 8
The files contain the following information:time [decimal year], mass change [gigatons], error [gigatons].
Each file is complemented by a quicklook image in png format.
The GMB mass change trends over different 5-year periods are also provided in grids (ascii format) in the folder mass_trends
The linear trend grids are given in units of millimeter water equivalent per year.
Data source: GRACE and GRACE-FO monthly solutions provided by CSR RL06.2
GIA correction: Caron et al. 2018
Basin definitions and further data descriptions can be found in the ST-DTU-ESA-GISCCI-ATBD-001_v3.0.doc and ST-DTU-ESA-GISCCI-PSD_v2.2.doc which can be found on the project website: http://esa-icesheets-greenland-cci.org/GMB products by DTU Space are derived with the inversion method described in Barletta et a. 2013.(http://www.the-cryosphere.net/7/1411/2013/tc-7-1411-2013.html)

The main change from the previous version 2.4 is the packaging. The minor change is the update in the time series.
