Graphical Abstract

Plain Language Summary: This study aimed to improve understanding of the differences in surface air temperature data between homogenized observations and reanalysis (20CR and ERA20C) since the beginning of the 20th century and to address the reanalysis data error.

Highlights:

• For ERA20C and 20CR, there was a high consistency with ADJ in annual variation characteristics after 1975. There were large fluctuations of REA during 1960–1970.
• The differences between 20CR and ADJ were large before the 1950s, and ERA20C was generally closer to ADJ.
• The annual variation characteristics of REA had a higher agreement with those of ADJ in winter and spring than in summer and autumn.
