CLM/CTSM glacier input datasets used for study on evaluation variable-resolution CESM2 in High-Mountain Asia

<strong>General Info</strong> This data archive contains the updated glacier-cover and glacier regions for the Community Land Model version 5 (CLM5)/Community Terrestrial Systems Model (CTSM). The updated glacier-cover and glacier regions are used for a study on the evaluation of variable-resolution (VR) CESM2 in High Mountain Asia (https://tc.copernicus.org/preprints/tc-2022-256/). The data archive also contains the model scripts and input files that have been used to create the glacier-cover dataset. The global glacier outlines used for the glacier-cover dataset were retrieved from the Randolph Glacier Inventory version 6 (RGI-Consortium, 2017). The vector data for the Greenland and Antarctic ice sheets were retrieved from the masks of Bedmachine version 4 (Morlighem et al., 2017, 2021) and version 2 (Morlighem et al., 2020; Morlighem, 2020), respectively. <strong>Contact</strong> René Wijngaard ([e-mail] / [e-mail]) <strong>Dataset Contents </strong> <pre><code>mksrf_glacier_3x3min_simyr2000.c210708.nc</code></pre> The updated glacier-cover dataset, encompassing three 3-minute datasets: 1) fractional land ice coverage, including both glaciers and ice sheets (PCT_GLACIER), 2) distributions of areal glacier coverage by elevation (PCT_GLC_GIC), and 3) distributions of areal ice-sheet coverage by elevation (PCT_GLC_ICESHEET). <pre><code>mksrf_GlacierRegion_10x10min_nomask_c200813.nc</code></pre> The updated glacier regions, encompassing five different glacier regions (0 - Other regions, 1 - Inside standard CISM grid but outside Greenland itself, 2 - Greenland, 3 - Antarctica, and 4 - High Mountain Asia (new)), used to set the ice melt and runoff behaviour in CLM5/CTSM (more detailed information can be found in the CLM5 Documentation, https://escomp.github.io/ctsm-docs/) <pre><code>model_scripts.tar</code></pre> Model scripts used for creating the glacier-cover dataset. A README file is included that lists instructions on how to make the glacier-cover dataset. <pre><code>glacier_final.tar</code></pre> Input files used to create the glacier-cover dataset. The following files are included: a global 30-arcsec merged BedMachine/GMTED2010 elevation dataset (gmted_bedmachine_stitched.nc) and land-sea mask (gmted2010_modis-rawdata-lonshift.nc), Antarctica land mask (BedMachineAntarcticaRotate2RotateBack_2020-07-15_v02_lonshift.map_TO_30arcsec.nc), Greenland land mask (BedMachineGreenland-2021-04-20.map_TO_30arcsec.nc), and 30-arcsec datasets encompassing glacier-cover (30arcsec_00_rgi60_World.nc) and ice-sheet cover (30arcsec_00_BM_World.nc).<strong>通用信息</strong> 本数据档案包含适用于第5版通用陆面模型（Community Land Model version 5, CLM5）/通用陆地系统模型（Community Terrestrial Systems Model, CTSM）的更新版冰川覆盖范围与冰川区域数据集。该更新后的冰川覆盖与冰川区域数据集被用于一项针对高亚洲地区变分辨率（variable-resolution, VR）第2版社区地球系统模型（CESM2）的评估研究（https://tc.copernicus.org/preprints/tc-2022-256/）。本数据档案同时包含用于构建该冰川覆盖数据集的模型脚本与输入文件。本次冰川覆盖数据集所用的全球冰川轮廓数据取自第6版伦道夫冰川名录（Randolph Glacier Inventory version 6, RGI-Consortium, 2017）；格陵兰岛与南极洲冰盖的矢量数据则分别取自Bedmachine第4版（Morlighem等，2017、2021）与第2版（Morlighem等，2020；Morlighem, 2020）的掩膜数据集。<strong>联系方式</strong> René Wijngaard ([e-mail] / [e-mail])<strong>数据集内容</strong><pre><code>mksrf_glacier_3x3min_simyr2000.c210708.nc</code></pre>该更新版冰川覆盖数据集包含3套3弧分分辨率数据集：1）陆地冰覆盖占比（涵盖冰川与冰盖，变量名PCT_GLACIER），2）按海拔划分的冰川面积占比分布（变量名PCT_GLC_GIC），以及3）按海拔划分的冰盖面积占比分布（变量名PCT_GLC_ICESHEET）。<pre><code>mksrf_GlacierRegion_10x10min_nomask_c200813.nc</code></pre>该更新版冰川区域数据集包含5类冰川区域（0-其他区域，1-位于标准CISM网格内但格陵兰岛域外，2-格陵兰岛，3-南极洲，4-高亚洲地区（新增）），用于在CLM5/CTSM中配置冰融与径流行为（详细信息可参考CLM5官方文档：https://escomp.github.io/ctsm-docs/）。<pre><code>model_scripts.tar</code></pre>用于生成冰川覆盖数据集的模型脚本，内含README文件，列明了构建该冰川覆盖数据集的操作指南。<pre><code>glacier_final.tar</code></pre>用于生成冰川覆盖数据集的输入文件，包含以下文件：全球30弧秒分辨率的BedMachine/GMTED2010融合高程数据集（gmted_bedmachine_stitched.nc）与海陆掩膜（gmted2010_modis-rawdata-lonshift.nc）、南极洲陆地掩膜（BedMachineAntarcticaRotate2RotateBack_2020-07-15_v02_lonshift.map_TO_30arcsec.nc）、格陵兰岛陆地掩膜（BedMachineGreenland-2021-04-20.map_TO_30arcsec.nc），以及涵盖冰川覆盖（30arcsec_00_rgi60_World.nc）与冰盖覆盖（30arcsec_00_BM_World.nc）的30弧秒分辨率数据集。
