title: A 500-year runoff reconstruction for European catchments

description: Runoff is an important hydrological variable for determining past hydrological pattern and extremities but the hydrological variables are available for short time period. This paper reconstructs runoff series from European catchment since 1500 AD. The study used basin average precipitation and temperature that were estimated from the reconstructed forcing by averaging the grid cells covering the specific catchment boundary. Similarly, we calculated the average catchment PDSI from the OWDA.** (1) Content **At each folder, files are saved with the station river names, which correspond to the station identifiers (GRDCno) are listed below.<b> GRDCno</b> <b>station_river</b>6123100 Montjean_Loire6123300 Blois_Loire6335020 Rees_Rhine6335060 Koeln_Rhine6335301 Neuerhafen_Main6335500 Weurzburg_Main6337200 Intschede_Wesser6337400 HannMuenden_Wesser6337514 Bodenwerder_Wesser6340120 Dresden_Elbe6343100 Wasserburg_Inn6742200 Orsova_Danube6935051 BaselRheinhalle_Rhine6935052 BaselSchifflaende_Rhine** (1.1) Folder "Input_data"Each files contains such fields1 "<b>GRDCno"</b> GRDC station ID2 "<b>station_river"</b> Station name corresponding to river ( e.g Blois_Loire)3 "<b>long"</b> Longitude of station4 "<b>lat" </b> Latitude of station5 "<b>time"</b> Time period between 1500 to 2000 6 "<b>pdsi" </b> Average of scPDSI from Old World drought Atlas across each basin7 "<b>gPR"</b> Average of Gridded seasonal precipitation (mm) at individual catchment 8 "<b>gTAS"</b> Average of Gridded seasonal temperature (degree C) at individual catchment 9 <b>R</b> Observed runoff (mm) from Global runoff dataset (GRDC).
