Physico-chemical data of throughfall under an old spruce stand planted around 1900. A sample is taken every fortnight for laboratory analysis. Parameters measured are pH, conductivity (µS/cm), Dissolved Organic Carbon (DOC, ppm), alkalinity (meq/l) and molar concentrations of Na+, K+, Ca2+, Mg2+, NH4+, Cl-, NO3- and SO42- (µmol/l). Since July 2013, the trees have been damaged by attacks from bark beetles (macrophagous insect pests), leading to the death of individual trees. Several sanitary cuttings were carried out in 2014, 2019 and 2022. Since autumn 2022, no trees dating back to the 1900 plantation have survived.

Physico-chemical data of open field precipitations collected at the meteorological station AH located at the top of the Strengbach catchment. A sample is taken every fortnight for laboratory analysis. Parameters measured are pH, conductivity (µS/cm), Dissolved Organic Carbon (DOC, ppm), alkalinity (meq/l) and molar concentrations of Na+, K+, Ca2+, Mg2+, NH4+, Cl-, NO3- and SO42- (µmol/l).

Physico-chemical data for spring water from the Strengbach catchment area. Four springs are collected in a spring collector containing a mixing basin. This underground spring collector collects four independent springs: CS1, CS2, CS3 and CS4 and a spring mixture: CR. The spring mix CR contributes to the drinking water supply of the village of Aubure (68, France). Parameters measured are pH, conductivity (µS/cm), Dissolved Organic Carbon (DOC, ppm), alkalinity (meq/l), Dissolved Organic Carbon DOC, alkalinity and molar concentrations of Na+, K+, Ca2+, Mg2+, Cl-, NO3-, SO42- and Si - (µmol/l). The CR spring is sampled every two weeks, while the four sources CS1, CS2, CS3 and CS4 are sampled less frequently (6 to 8 weeks depending on the period).

Physico-chemical data for stream water from the Strengbach watershed outlet. A sample is taken every fortnight for laboratory analysis. Parameters measured are pH, conductivity (µS/cm), Dissolved Organic Carbon (DOC, ppm), alkalinity (meq/l), Dissolved Organic Carbon DOC, alkalinity and molar concentrations of Na+, K+, Ca2+, Mg2+, Cl-, NO3-, SO42- and Si - (µmol/l).

Physico-chemical data of throughfall precipitations under a beech stand planted between 1825 and 1845. A sample is taken every fortnight for laboratory analysis. Parameters measured are pH, conductivity (µS/cm), Dissolved Organic Carbon (DOC, ppm), alkalinity (meq/l) and molar concentrations of Na+, K+, Ca2+, Mg2+, NH4+, Cl-, NO3- and SO42- (µmol/l).

The dataset contains the water level and discharge measured at the Strengbach catchment outlet since September 1986.

The dataset comprises 5 variables, corresponding to: Air temperature (°C), Precipitation (mm), Relative humidity (%), Global (solar) radiation (W/m2), Wind speed (m/s)
