Interpolated Daily Temperature and Precipitation Data for Level II ICP Forests Plots in Germany

A harmonized, comprehensive meteorological time series for 78 German intensive forest monitoring plots (Level II) has been made available from 1961-2019. The used hybrid spatial interpolation routine using simple linear regression and inverse distance weighting allows for gap-filling of missing data and also for extrapolation outside measurement period to analyze long-term effects of climate on forest ecosystems.
