ESA Permafrost Climate Change Initiative (Permafrost_cci): Permafrost Ground Temperature for the Northern Hemisphere, v1.0

This dataset contains permafrost ground temperature data produced as part of the European Space Agency's (ESA) Climate Change Initiative (CCI) Permafrost project. It forms part of the Beta version of their Climate Research Data Package (CRDP v0). It is derived from a thermal model driven and constrained by satellite data. Grid products of CDRP v0 are released in annual files, covering the start to the end of the Julian year. This corresponds to average annual ground temperatures and is provided for specific depths (surface, 1m, 2m, 5m , 10m) for the Northern Hemisphere (north of 30°) for the period 2003-2017.

本数据集收录欧洲空间局（European Space Agency, ESA）气候变化倡议（Climate Change Initiative, CCI）多年冻土项目产出的多年冻土地下温度数据。该数据集属于其气候研究数据包（Climate Research Data Package, CRDP v0）的Beta测试版。其数据源自受卫星数据驱动与约束的热模型。CRDP v0的格点产品以年度文件形式发布，覆盖完整儒略年的全部时段。数据集提供了2003年至2017年期间北纬30度以北北半球区域，地表、1米、2米、5米、10米等指定深度的年均地温数据。
