A Big Earth Data Platform for Three Poles

In order to find out the climate and environmental changes since the last interglacial period in Central Asia, the earth ring Institute of Chinese Academy of Sciences, taking tree rings, lakes, stalagmites and loess as carriers, conducted in-depth research on their evolution from different aspects. The tree ring group collected tree ring samples and obtained the data of tree ring width in alagan, Yuli County, Xinjiang; The lake marsh formation collected lake marsh sediments in Kashgar basin and obtained 137cs-210pb, LOI δ 18O data; The stalagmites collected by the stalagmite formation in qiongguo cave, Qinghai Tibet Plateau have obtained carbon and oxygen isotopes, test age and element test data; The comprehensive group obtained the XRF and multi parameter data of peat in Longmucuo and dangyayongcuo lakes, the particle size of Longmucuo in Lop Nur, Xinjiang and Tibet, the magnetic susceptibility of peat in Kashgar and Longmucuo lakes, and the TOC data of Zhaosu; The Loess group obtained the OSL ages, MS and carbon epitope data of the Loess of xiaoerbu, Zhaosu and Qingshuihe in Xinjiang. It provides strong scientific data support for climate and environmental changes since the last interglacial period in Central Asia.

2.Tree ring width and reconstructed precipitation soil water condition data series of the Northeastern Tibetan Plateau and dating data of the Delingha Area (1580B.C.-2006A.D.)

This dataset contains monthly 0.05°×0.05° (1982, 1985, 1990, 1995, and 2000) and 0.01°×0.01° (2005, 2010, 2015 and 2017) LST products in Qilian Mountain Area. The dataset was produced based on SW algorithm by AVHRR BT from thermal infrared channels (CH4: 10.5µm to 11.3µm; CH5: 11.5µm to 12.5µm) at a resolution of 0.05°, MYD21A1 LST products at a resolution of 0.01° along with some auxiliary datasets. The auxiliary datasets include IGBP land cover type, AVHRR NDVI products, Modern Era Retrospective-Analysis for Research and Applications-2 (MERRA-2) reanalysis data, ASTER GED, Lat/Lon and the Julian Day information.
