2046-2065年不同RCP情景下三极多年冻土范围后处理集合产品

三极多年冻土范围原始数据通过GCM模型模拟生成，原始数据来源于http://www.cryosphere.csdb.cn/portal/metadata/5abef388-3f3f-4802-b3de-f4d233cb333b。本数据集包含了未来2046-2065年间不同典型浓度路径（Representative Concentration Pathways，RCP）下的未来情景预估，包括RCP2.6情景、RCP4.5情景、RCP8.5情景。原始数据内容是青藏高原的永久冻土和季节冻土的空间范围，数据格式为NetCDF4格式，数据空间分辨率为0.5°，时间分辨率为年。本研究工作通过对其进行数据格式转换、空间插值等后处理操作，生成了NetCDF4格式的多年冻土范围数据，其空间分辨率为0.1°，时间分辨率为年，时间范围为2046-2065年，多年冻土用1表示，季节冻土用0表示。The raw data of permafrost and seasonally frozen ground extent over the Third Pole was generated via General Circulation Model (GCM) simulations, and the original dataset is sourced from http://www.cryosphere.csdb.cn/portal/metadata/5abef388-3f3f-4802-b3de-f4d233cb333b. This original dataset contains future scenario projections under different Representative Concentration Pathways (RCPs) for the period 2046–2065, including RCP2.6, RCP4.5, and RCP8.5 scenarios. The raw data depicts the spatial extents of permafrost and seasonally frozen ground over the Tibetan Plateau, with a data format of NetCDF4, a spatial resolution of 0.5°, and an annual temporal resolution. In this study, post-processing operations including data format conversion and spatial interpolation were performed on the raw data to generate updated permafrost extent datasets in NetCDF4 format. The processed datasets have a spatial resolution of 0.1°, an annual temporal resolution, and cover the period 2046–2065, where permafrost is denoted by 1 and seasonally frozen ground by 0.
