The data set of ecological adjustment value of Arctic permafrost change from 1982 to 2015, with the time resolution of 1982, 2015 and the change rate of two phases, covers the entire Arctic tundra area, with the spatial resolution of 8km. Based on multi-source remote sensing, simulation, statistics and measured data, and combined with GIS and ecological methods, it quantifies the adjustment service value of Arctic permafrost to the ecosystem, The unit price refers to the correlation (0.35) between the active layer thickness and NDVI changes after excluding precipitation and snow water equivalent, and the grassland ecosystem service value (the unit price of tundra ecosystem service is based on 1/3 of the grassland ecosystem service value).

File naming and required software

File name: The Arctic permafrost change ecological adjustment value data set is stored in text format. The file name is "yyyydd.txt", where yyyy represents the year and ddd represents Julian date.
Data reading method: All ASCII code files in the data set can be directly opened with a text program (such as Notepad). Except for the header file, the main content is a numerical representation of the ecological adjustment value of Arctic permafrost changes. If it is necessary to display it with a diagram, it can be opened with Arcgis. During the reading process, a file in grid format will be generated, and the displayed grid file is the graphical representation of the ASCII code file.
