There are 396 temperature-sensitive proxy data for the past millennium over the Northern Hemisphere, including 370 tree rings, 15 ice cores, 9 lake sediments and 2 historical documents; This data is derived from the global temperature proxy dataset released by PAGES2k Consortum in 2017; During the process of temperature assimilation in the past millennium (1000-2000 AD) in the Northern Hemisphere, the data were further screened, and only the data with annual resolution were retained; The proxy data contained in the dataset have passed strict quality inspection and temperature signal verification; The data set can be used to reconstruct the temperature of the Northern Hemisphere at the hemispherical and regional scales for the past millennium.

File naming and required software

File name: The file is stored in the format of. mat file. The name of the file is "proxy_var_startyr_endyr_geocoverage. mat", where proxy means surrogate data, var means climate variable name, startyr means data start year, endyr means data end year, and geocoverage means data space coverage.
Data reading method: All data in the dataset can be read by using Matlab software. Rows 1-3 of the dataset represent: data type (1: tree ring; 2: ice core; 3: lake sediments; 4: historical documents), longitude, latitude. Rows 4-1004 in column 1 of the data represent years.
