Greenland Ice Sheet Basal Melt

This dataset contains basal melt rates as published in Karlsson et al., (2021). The data can be accessed in three formats NetCDF, ascii and Matlab. The data contain basal melt rates in metres per year from three different heat sources: geothermal flux, friction heat and viscous heat from surface meltwater. The data also contain the total basal melt rates in metres per year (the sum of the three terms). Uncertainties for each term is named X_unc. Note that the geothermal flux has an asymetrical uncertainty. The uncertainty for the total melt rates are found by root squared sum of uncertainties. See README.txt for more information.

本数据集包含卡尔松等人（Karlsson et al., 2021）发表的基底消融速率数据。该数据集提供三种格式的访问方式：NetCDF、ASCII以及Matlab格式。数据涵盖三种不同热源下的年际基底消融速率（单位：米/年），分别为地热通量、摩擦热与地表融水产生的黏滞热。数据集同时包含总基底消融速率（单位：米/年，为上述三项之和）。各分项的不确定性以X_unc命名。需注意，地热通量的不确定性为非对称分布。总消融速率的不确定性通过各分项不确定性的平方和开方计算得到。更多详细信息请参阅README.txt文件。
