Millennial temperature datasets over the three poles produced by paleoclimate data assimilation

Millennial temperature datasets over the three poles produced by paleoclimate data assimilation


(1) Data content: Millennial temperature (near-surface air temperature anomaly based on the millinnial mean)datasets over the three poles, e.g., Arctic, Antarctic, and Qinghai-Tibet Plateau; (2) Data sources and processing methods: These datasets were produced by the authors themselves using the paleoclimate data assimilationand approach based on climatic proxies over the three poles; (3) Description of data quality: There are high spatio-temporal consistency between these datasets and several instrumental gridded temperature datasets (correlation coefficient above 0.6, p <0.001; Nash efficiency coefficient above 0.5). In addition, the correlations between these datasets and several proxy-based temperature series are between 0.4 and 0.8 (p <0.001). (4) Data application achievements and prospects: These datasets can be used to investigate the temporal and spatial variations in temperature over the three poles during the past millennium.


File naming and required software

These datasets are stored in netCDF format. The data file are named as follows: Production method _ geographical name _ variable type _ Start year _ End year. Nc
The names of the three files are PDA_Arctic_SAT_1000_2000.nc; PDA_Antarctic_SAT_1000_2000.nc; PDA_QTP_SAT_1000_2000.nc
These datasets can be opened and used by tools such as Panoply, NCL, and Matlab.
