Gravitational mass balance of Greenland 2003 to present v2.3

Greenland mass balance (GMB) product for the Greenland Ice Sheet from GRACE(-FO) satellite gravimetry (CSR RL06) by DTU Space, computed with the mass point inversion method.GMB mass change trends over different 5-year periods are derived by DTU Space within the ESA CCI GIS project and are provided in the following file:CCI_GMB_GIS_DTU.nc The linear trend grids are given in units of millimeter water equivalent per year.The following files are also provided for GMB temporal mass changes derived by DTU Space within the ESA CCI GIS project.GIS00_grace.dat : all GISGIS01_grace.dat : Basin 1GIS02_grace.dat : Basin 2GIS03_grace.dat : Basin 3GIS04_grace.dat : Basin 4GIS05_grace.dat : Basin 5GIS06_grace.dat : Basin 6GIS07_grace.dat : Basin 7GIS08_grace.dat : Basin 8The files contain the following information:time [decimal year], mass change [gigatons], error [gigatons]Each file is complemented by a quicklook image in png format.Data source: GRACE and GRACE-FO monthly solutions provided by CSR RL06 GIA correction: Caron et al. 2018Basin 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)Citation: Barletta, V.

格陵兰冰盖质量平衡（GMB）产品由丹麦技术大学空间研究所（DTU Space）基于GRACE(-FO)卫星重力测量（CSR RL06）数据计算得出，采用质量点反演法。在ESA CCI GIS项目中，DTU Space推导了不同五年期的GMB质量变化趋势，并在以下文件中提供：CCI_GMB_GIS_DTU.nc。线性趋势网格以每年毫米水当量为单位给出。以下文件也由DTU Space在ESA CCI GIS项目中推导的GMB时间质量变化提供：GIS00_grace.dat：所有GIS；GIS01_grace.dat：流域1；GIS02_grace.dat：流域2；GIS03_grace.dat：流域3；GIS04_grace.dat：流域4；GIS05_grace.dat：流域5；GIS06_grace.dat：流域6；GIS07_grace.dat：流域7；GIS08_grace.dat：流域8。文件包含以下信息：时间[小数年份]，质量变化[十亿吨]，误差[十亿吨]。每个文件均配有png格式的快速查看图像。数据源：由CSR RL06提供的GRACE和GRACE-FO月度解决方案；GIA校正：Caron等人，2018年。流域定义及进一步的数据描述可查阅ST-DTU-ESA-GISCCI-ATBD-001_v3.0.doc和ST-DTU-ESA-GISCCI-PSD_v2.2.doc，这些文档可在项目网站找到：http://esa-icesheets-greenland-cci.org/。DTU Space的GMB产品是基于Barletta等人（2013年）描述的反演方法推导的。（http://www.the-cryosphere.net/7/1411/2013/tc-7-1411-2013.html）引用：Barletta, V.
