Water storage changes of a shallow groundwater site determined with a weighable groundwater lysimeter and measured volumetric water contents

The data set contains daily values of a weather station (precipitation, grass reference evapotranspiration) and a weighable groundwater lysimeter (groundwater level, monolith mass, volumetric water contents in 8 depths of the monolith) from 1st December 2018 to 30th November 2019. The study site with the lysimeter station is in the Spreewald wetland. All technical details of the lysimeter station are described in Dietrich et al. (2016). The used soil moisture profile probe (EnviroScan, Sentek) consists of 8 capacitive sensors in measurement depths of 10, 20, 30, 40, 50, 60, 90 and 120 cm. The sensors were soil specifically calibrated with a soil specifically calibrated Diviner probe (Dietrich & Steidl, 2021).
The water content measurements were used for a calculation of the whole water content in the soil profile up to 135 cm depth and the water storage change related to the starting point on 1st December 2018. The estimated water storage change can be compared and evaluated to the water storage change based on the mass weight change.
