The model used in the study is a particular version of the Community Earth System Model (CESM) version 1.3 (CESM1.3-beta17_sehires18) based on its earlier version, which has been run and evaluated thoroughly for century-long climate simulations in a high-resolution configuration (Chang et al., 2020). This data is based on historical experiment, consisting the meteorological factors related to the precipitation in summer over East Asia. The time range of the data is from 1979 to 2005.
