G2DC-PL+ A gridded 2 km daily climate dataset for the union of Polish territory and the Vistula and Odra basins

The G2DC-PL+ is a 2 km gridded daily climate dataset for the union of Polish territory and the Vistula and Odra basins, constructed with the purpose of using it as forcing data for various kinds of environmental models. It is an update and extension of the CPLFD-GDPT5 dataset (doi: 10.4121/uuid:e939aec0-bdd1-440f-bd1e-c49ff10d0a07). It includes five variables: precipitation, minimum temperature, maximum temperature, relative humidity and wind speed. Interpolation was performed using geostatistical techniques such as kriging with external drift, universal kriging and indicator kriging. Raw input data (daily station-based time series) were acquired from various providers: IMGW-PIB (area of Poland), ECA&D and NOAA-NCDC (neighbouring countries). Data are available at three temporal aggregations (daily, monthly and annual). Nine NetCDF files, each for the period 1951-2019, are made available.
