AB  - The global surface temperature observation dataset is the foundation of global warming research. Against the backdrop of intensified global warming and frequent extreme events, it is necessary to increase coverage and reduce the uncertainty of global surface temperature datasets. China has updated the Global Consolidated Surface Temperature Interim (CMST Interim) to achieve CMST 2.0 in this study. The previous CMST dataset was developed by merging China's global land surface temperature (C-LSAT) with ocean surface temperature (SST) data from extended reconstruction of sea surface temperature (ERSSTv5). CMST 2.0 includes three variants: CMST 2.0-Nrec (no reconstruction), CMST 2.0-Imax, and CMST 2.0-Imin (based on the reconstructed sea air temperature of the Arctic ice surface). The reconstructed dataset significantly improves data coverage, while CMST 2.0-Imax and CMST 2.0-Imin have improved coverage in the northern hemisphere, reaching over 95%, thus increasing long-term trends at global, hemisphere, and regional scales from 1850 to 2020. Compared with CMST Interim, CMST 2.0-Imax, and CMST 2.0-Imin, it shows that the high spatial coverage extends to high latitude regions and is more consistent with the reference of multi dataset averages in polar regions.
