Abstract: Water and matter fluxes in the critical zone are controlled by complex environ-mental processes. For example, dynamic soil structure interacting with land man-agement and bio-geo-chemical processes during plant growth affecting both soil water storage and conductivity functions. High precision weighable lysimeters allow quantification of water and nutrient cycling in the soil, plant development, and often neglected processes at night, such as dew formation or evapotranspiration. Highly precise and temporally resolved data from weighable lysimeters consider feedbacks across the entire hydrological cycle, from the soil to the atmosphere, allowing for a more holistic understanding the dynamics of water flow and solute transport (nutri-ents or contaminants) in soil. Data regarding the soil water balance will be compared from different landscapes and networks (e.g., TERENO SOILCan, SUPREHILL and WET-ARID) that are important for understanding the hydrological cycle and for stud-ying land-atmosphere interactions. The presented holistic datasets are crucial for developing and calibrating models, as well as for the quantification of soil-vegetation-atmosphere processes under real field conditions.
