资源简介:
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。在欧盟地球系统变化和监测计划(ESA CCI)的格陵兰冰盖观测(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。此外,还提供了以下由DTU Space在ESA CCI GIS项目中推导的GMB时间质量变化文件:GIS00_grace.dat(全部GIS)、GIS01_grace.dat(盆地1)、GIS02_grace.dat(盆地2)、GIS03_grace.dat(盆地3)、GIS04_grace.dat(盆地4)、GIS05_grace.dat(盆地5)、GIS06_grace.dat(盆地6)、GIS07_grace.dat(盆地7)、GIS08_grace.dat(盆地8)。这些文件包含以下信息:时间[十进制年]、质量变化[十亿吨]、误差[十亿吨]。每个文件均附有png格式的快速查看图像。数据来源:由CSR RL06提供的GRACE和GRACE-FO月度解决方案,GIA校正:Caron等人,2018年。盆地的定义和进一步的数据描述可在ST-DTU-ESA-GISCCI-ATBD-001_v3.0.doc和ST-DTU-ESA-GISCCI-PSD_v2.2.doc文件中找到,这些文件可在项目网站上查阅:http://esa-icesheets-greenland-cci.org/。DTU Space的GMB产品是通过Barletta等人(2013年)所述的反演方法得出的。(http://www.the-cryosphere.net/7/1411/2013/tc-7-1411-2013.html)引用:Barletta, V.
