Multicompartment and multiscale long-term observation research are important prerequisites to tackling the scientific challenges resulting from climate global change. Long-term monitoring programs cost intensive require high analytical standards, however, gain of knowledge often requires longer times. Nevertheless, several environmental networks have been established in recent years, focusing on impact land use change terrestrial ecosystems. From 2008 onward, a network Terrestrial...
Core Ideas We provide an overview of the TERENO-Rur hydrological observatory. present information on general physical characteristics Rur catchment. Ongoing interdisciplinary research aims to advance understanding complex processes. observatory, which is main observational platform TERENO (TERrestrial ENvironmental Observatories) Eifel/Lower Rhine Valley Observatory. The catchment area exhibits distinct gradients in altitude, climate, land use, soil properties, and geology. Eifel National...
Abstract. This study compares actual evapotranspiration (ETa) measurements by a set of six weighable lysimeters, ETa estimates obtained with the eddy covariance (EC) method, and calculated full-form Penman–Monteith equation (ETPM) for Rollesbroich site in Eifel (western Germany). The comparison measured EC (including correction energy balance deficit) lysimeters is rarely reported literature allows more insight into performance both methods. An evaluation two methods year 2012 shows good...
Large weighable lysimeters allow a precise determination of the soil water balance and quantification both exchange at soil-atmosphere interface flux below root zone toward groundwater. If well embedded into an equally-vegetated environment, they reach hitherto unprecedented accuracy in estimating precipitation (P) by rain, dew, fog, rime snow, evapotranspiration (ET). Lysimeters largely avoid errors made traditional measurement systems, such as wind error Hellmann rain gauges, island...
Abstract We examined 3 years of measured daily values all major water budget components (precipitation P , potential evapotranspiration PET actual ET and runoff R ) volumetric soil content θ a small, forested catchment located in the west Germany. The spatial distribution was determined from wireless sensor network 109 points with measurement depths each; calculated eddy‐covariance tower measurements. dominantly energy limited, amounting to approximately 90% ratio R/P 56%. closed long‐term...
Core Ideas To determine the water retention curve from inverse modeling, θ and ψ need to be monitored. δ 18 O ratios contained information inversely estimate soil hydraulic parameters.

Atrazine (2-chloro-4-ethylamino-6-isopropylamino-1,3,5-triazine) groundwater monitoring in the Zwischenscholle aquifer western Germany revealed concentrations exceeding threshold value of 0.1 μg L−1 and increasing concentration trends even 20 yr after its ban. Accordingly, hypothesis was raised that a continued release bound atrazine residues from soil into combination with low degradation contributes to elevated groundwater. Three cores reaching down table were taken an agricultural field...
Core Ideas The water flux in lysimeters with a tension‐controlled bottom boundary depends strongly on the applied pressure head. surrounding subsurface conditions have significant influence measured heads that are used to control of transferred lysimeters. Use nonappropriate table depths and soil textural properties which do not correspond where lysimeter originated can lead large differences fluxes. should be managed by from site was taken order enable direct comparison changes soils...
Abstract Evapotranspiration ( ET ) is, after precipitation, the second largest flux at land surface in water cycle and occurs mainly during daytime. Less attention has been given to fluxes from into atmosphere nighttime (i.e., between sunset sunrise). The N may be estimated based on models that use meteorological data; however, due missing experimental long‐term data, verification of estimates is limited. In this paper, amount for two grassland ecosystems was determined highly temporally...
