Dataset: Bedrock Permafrost in Sisimiut, West Greenland

This dataset contains the original data for the manuscirpt by Marcer et al, Modeling present and future rock wall permafrost distribution in the Sisimiut mountain area, West Greenland. The data are the basis to develop, calibrate and validate the numerical model describing rock wall permafrost in the Sisimiut area. The data consist of:Rock surface temperature data acquired during the hydrological years 2020-2022. The data are acquired by a network of 9 loggers installed in steep rock walls. Here, we provide the RST time series as .csv file, along with air temperature and incoming solar radiation evaluated using the TopoSCALE algorithm. The data are accompained by a .shp file describing loggers locations - EPSG 3413. Shp file can be open using any GIS software, e.g. Qgis.Field ERT acquired in October 2020. The data are acquired using Electrical Resistivity Tomography along a 100 m transect across a mid-elevation mountain ridge. Data are provided as .xls file and can be handled using Res2inv. The profile location is given as .shp file. Shp file can be open using any GIS software, e.g. Qgis.Laboratory data of rock samples acquired at the geophysical transect location. The data are provided as .xls file and describe the results of the petrophysical analysis linking samples' temperature and measured conductivity.Georasters providing the GIS data for visualization of the terrain in the study. All data is at 10 m resolution and ESPG 3413. We provide the DEM, derived from the Arctic DEM V3.0; the potential incoming solar radiation map. As modeling results, we provide georasters of mean rock surface temperatures during three climatic settings: present conditions (2002-2022), and at the end of the 21st century under the two scenarios RCP 2.6 and RCP 8.5. Georasters file can be open using any GIS software, e.g. Qgis.

本数据集收录了Marcer等人在《西格陵兰西西米乌特山区岩石壁永久冻土分布的现状与未来建模》一文中使用的原始数据。这些数据是构建、校准和验证描述西西米乌特地区岩石壁永久冻土的数值模型的基础。数据内容包括：

- 2020-2022水文年期间采集的岩石表面温度数据。数据通过安装在陡峭岩石壁上的9个数据记录器获得。在此，我们提供岩石表面温度时间序列数据（.csv文件），以及使用TopoSCALE算法评估的空气温度和入射太阳辐射数据。

- 数据附带描述记录器位置的.shp文件，采用EPSG 3413坐标系。shp文件可用任何GIS软件打开，例如Qgis。

- 2020年10月采集的地面电阻率层析成像（ERT）数据。数据通过在中高海拔山脊100米横断面进行采集。数据以.xls文件形式提供，并可由Res2inv软件处理。横断面位置以.shp文件给出。shp文件可用任何GIS软件打开，例如Qgis。

- 在地球物理横断面位置采集的岩石样本实验室数据。数据以.xls文件形式提供，描述了将样本温度与测量电导率相联系岩石物理分析的结果。

- 提供的地理栅格数据用于可视化研究区域的地面地形。所有数据分辨率为10米，坐标系为EPSG 3413。我们提供由北极DEM V3.0派生的数字高程模型（DEM）以及潜在入射太阳辐射图。作为建模结果，我们还提供在三种气候设置下平均岩石表面温度的地理栅格数据：当前条件（2002-2022年），以及21世纪末在两种情景（RCP 2.6和RCP 8.5）下的预测。地理栅格文件可用任何GIS软件打开，例如Qgis。
