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

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


(1) Data content: data set of precipitation field of the three poles (Arctic, Antarctic and Qinghai Tibet Plateau) in the past millennium; (2) Data source and processing method: the data is independently produced by the author and is produced by assimilating the precipitation proxy data in the three polar regions through the paleoclimate data assimilation method; (3) Data quality description: there is a high degree of spatial-temporal consistency between the data set and the precipitation data sets measured by multiple instruments (correlation coefficient is above 0.35, P < 0.001; Nash efficiency coefficient is above 0.3). In addition, the correlation coefficient with multiple precipitation data series reconstructed based on proxy data is between 0.2 and 0.6 (P < 0.001); (4) It can be used to study the temporal and spatial changes of precipitation in the past millennium in the three polar regions.


File naming and required software

The data set is stored in NetCDF format, and the data file is named as variable name_ Time resolution_ Spatial resolution_ Production method_ Geographical name_ Start year:_ End year.nc
The names of the three files are: PR_ Ayr_ 2deg_ PDA_ Arctic_ 1000_ 2000.nc; pr_ Ayr_ 2deg_ PDA_ Antarctic_ 1000_ 2000.nc; pr_ Ayr_ 2deg_ PDA_ Tibetan_ 1000_ 2000.nc
This data can be opened and used by tools such as panoply, NCL, MATLAB, etc.
