We provide daily average water temperatures and discharge at following Rhine monitoring stations: Basel; Worms; Koblenz; Cologne. We provide the yearly heat input from Nuclear power plants between following stations: upstream Basel; between Basel and Worms; between Worms and Koblenz; between Koblenz and Cologne. We provide the calculated catchment wide air temperature, described in the paper https://doi.org/10.5194/hess-2019-518. The data is connected to the publication: Anthropogenic Influence on the Rhine water temperatures https://doi.org/10.5194/hess-24-5027-2020
