This is Northern Hemispheric (NH) annual near-surface temperature dataset during the past millennium with a 2° spatial resolution, which is produced using the paleoclimate data assimilation approach with EnSRF method, MPI-ESM-P model and 396 multi-proxies from the PAGES2k Consoritum. This dataset agrees well with several observational temperature datasets during the instrumental period, and has a similar level of reliability as the Twentieth Century Reanalysis which assimilates surface pressure observations. In addition, the dataset shows a high level of agreement with previous proxy-based reconstructions (average correlation of annual mean NH temperatures is r = 0.61). The dataset can be used to study the temperature variability over the NH and some regions of the NH during the past millennium (1000-2000 AD).

File naming and required software

This dataset is saved with format of netCDF, which is the common format in the field of meterology. The file is named with "variable name_variable type_wrt_anomaly period_temporal resolution_spatial resolution_producing method_start time_end time_multiProxy.nc"
This dataset can be opened and read by Panoply, Matlab, NCL, ArcGIS, etc.
