There is a lack of a set of high-resolution precipitation gridded data with long time series in the main basin of the Arctic. This dataset provides daily precipitation in the main basin of the Arctic. The range of data set is from 45 ° N to 76.15 °N. The metadata used includes: the meteorological station data during 1980-2015 obtained from GSOD and the reanalysis data of ERA-interim during 1980-2018. This dataset was obtained by bias correction of ERA-interim data with the improved quantile mapping method, and the background data used for bias correction is the interpolation gridded precipitation, in interpolation process, we not only take into account the effect of elevation, but fully consider the influence of wind on gauge measurements, the gauge used in interpolation all undergo bias adjustment. This dataset performs well both in region scale and cell grid scale, with high accuracy, which providing a set of reliable precipitation gridded data for the hydrological research of the Arctic.

File naming and required software

File name: the dataset contains two parts, TPS is interpolation gridded data, cor_ERA-interm is ERA-interim data after bias correction, data storage format is NetCDF format, data file name is named with corresponding date, such as yyyy mm dd, where yyyy indicates year, mm indicates month, dd indicates day. The unit is mm / d.
Data reading method: arcgis and panoply can be used to view the specific information of the data, CDO,NCL, etc can be used to further process.
