Melt Model Intercomparison parameter sets (Monte Carlo Simulations)

These are the 100 parameter sets (per site) of perturbed debris properties used to run the Monte Carlo simulations for the WGDCG Multi Model Intercomparison project. There is one file per site with 100 sets of the 4 parameters used and debris thickness. Details: - Debris thicknes is included in the files but remains unchanged (not perturbed). - A 10% uniformly distributed uncertainty range is applied to surface roughness (z0), thermal conductivity of debris (k) and porosity of debris (phi), 5% is applied for emissivity. The central value of the range is that one originally provided by the data provider, which can be consulted in the metadata files for each site. - 100 samples per parameter and location are taken randomly from the uncertainty range. UNITS: h_d: m z0: m k: W m-1 K-1 phi: fraction emissivity: unitless It will be open when published.

本数据集包含为WGDCG多模式比对项目（Multi Model Intercomparison project）开展蒙特卡洛模拟（Monte Carlo simulations）所需的、每个站点对应的100组扰动碎屑物性参数。每个站点对应一个数据文件，内含4项参数与碎屑厚度（debris thickness）的100组取值。
具体说明如下：
- 碎屑厚度（debris thickness）虽包含于文件中，但未进行扰动，保持初始定值不变。
- 对地表粗糙度（surface roughness，z0）、碎屑热导率（thermal conductivity of debris，k）与碎屑孔隙度（porosity of debris，φ）施加10%的均匀分布（uniformly distributed）不确定度范围（uncertainty range），对发射率（emissivity）施加5%的不确定度范围。该范围的中心值为数据提供者最初提供的基准值，各站点的基准值可通过对应站点的元数据文件（metadata files）查询。
- 针对每个参数与站点，从其对应的不确定度范围内随机抽取100个样本。
