Abstract：

The dataset of climate change impacting grain yield in Tibet of China (1993-2017) was developed based on the data from meteorological stations and statistical yearbooks, integrated with three statistical models. The climate factors include minimum temperature, precipitation, growing degree days and solar radiation. The dataset covers 7 prefecture-level cities, and 63 counties in Tibet (The other 11 counties are not counted due to the small area of cereal cultivation). The dataset includes the following data in Tibet during 1993-2017: (1) annual cereal yields at the prefecture-level cities; (2) annual cereal yields at each county; (3) annual climate data (including minimum air temperature, cumulative precipitation, growing degree days, and cumulative solar radiation) during the cereal growing season at the prefecture-level cities; (4) impacts of climate change on cereal yields. The dataset is archived in .xlsx and .shp data formats, and consists of 7 data files with data size of 7.99 MB (Compressed into one data file with 2.62 MB). The analysis paper based on the dataset was published in Acta Geographica Sinica, Vol. 76, No. 9, 2021.
