Global Climate-Ecological Pattern Evolution Product Dataset (1981-2100)- A Big Earth Data Platform for Three Poles

(1) Data content: The evolution product of the global climate-ecological pattern. The time range includes the historical period 1981-2020 with a spatial resolution of 0.5°, and the future period 2021-2100 (the future period contains four different shared socioeconomic pathways: SSP126, SSP245, SSP370, SSP585), with a spatial resolution of 1°, every 20 years 1 issue.

(2) Data source and processing method: The leaf area index data of GLOBMAP was selected as the basis in the historical period, and the leaf area index data of three CMIP6 models (ACCESS-ESM1-5, CanESM5, UKESM1-0-LL) were integrated in the future period. The relationship between temperature, precipitation and radiation and the leaf area index was constructed through multiple linear regression, and the corresponding coefficients were extracted to characterize the influence of each climate variable on the leaf area index. Finally, the RGB map was used to characterize the climatic factors of the leaf area index. Influence coefficient.

(3) Data quality description: Global 20-year period 1, historical period 2 period (1981-2000; 2001-2020), the future period includes four shared socio-economic paths (SSP126, SSP245, SSP370, SSP585), each path The next 4 issues (2021-2040; 2041-2060; 2061-2080; 2081-2100).

(4) Data application achievements and prospects: This data can be used for studies related to the evolution of vegetation and ecosystems in the context of climate change.

File naming and required software

File name: the global climate ecological pattern evolution products are stored in GeoTIFF format. The file name of the historical period is "* yyyy-yyyy. TIF", and the file name of the future period is "* # # # # & yyyy-yyyy. TIF", where * denotes climate variables (tasr denotes temperature, RSR denotes radiation, PRR denotes precipitation), # # # # denotes shared social and economic path, and yyyy denotes year, For example, prrssp126 & 2021-2040.tif represents the GeoTIFF file to describe the distribution results of the influence coefficient of the global leaf area index on the precipitation index under the shared socio-economic path ssp126 in 2021-2040.
Data reading method: all GeoTIFF files in the dataset can be opened with ArcGIS or envi. The main content is a value between 0 and 1. The closer the grid cell value is to 1, the stronger the Lai at the grid is controlled by the corresponding climate variables.
