***General Introduction***
This data set is a reconstructed synthetically Humidity Index (HI) in arid Central Asia over the past millennium based on the multiproxy sediment records (C/N ratios, MS, silt, and clay fractions) from Lake Dalongchi in the central Tianshan Mountains.

This research has been supported by the National Key Research and Development Program of China (Grant No. 2018YFA0606400), the National Natural Science Foundation of China (Grant No. 41907375), and the Basic Research Program of the Institute of Hydrogeology and Environmental Geology CAGS (Grant No. SK202007).

***Description of the data in this data set***
A = the years 1180 to 2018
B = indicating the humidity index changes
