+<blockquote>
+TERENO Eifel-Rur Observatory. TERENO (TERrestrial ENvironmental Observatories)
+spans an Earth observation network across Germany that extends from the 
+North German lowlands to the Bavarian Alps. This unique large-scale project 
+aims to catalogue the longterm ecological, social and economic impact of 
+global change at regional level. The central monitoring site of the TERENO 
+Eifel/Lower Rhine Valley Observatory is the catchment area of the River Rur. 
+It covers a total area of 2354 kmÂ² and exhibits a distinct land use gradient: 
+The lowland region in the northern part is characterised by urbanisation and 
+intensive agriculture whereas the low mountain range in the southern part is 
+sparsely populated and includes several drinking water reservoirs. 
+Furthermore, the Eifel National Park is situated in the southern part of the 
+Rur catchment serving as a reference site. Intensive test sites are placed 
+along a transect across the Rur catchments in representative land cover, soil, 
+and geologic settings. The Rollesbroich site is located in the low mountain 
+range "Eifel" near the German-Belgium border and covers the area of the small 
+Kieselbach catchment (40 ha) with altitudes ranging from 474 to 518 m.a.s.l.. 
+The climate is temperate maritime with a mean annual air temperature and 
+precipitation of 7.7 Â°C and 1033 mm, respectively, for the period from 1981 
+to 2001. The study site is highly instrumented. All components of the water 
+balance (e.g. precipitation, evapotranspiration, runoff, soil water content) 
+are continuously monitored using state-of-the-art instrumentation, including 
+weighable lysimeters, runoff gauges, cosmic-ray soil moisture sensors, a 
+wireless sensor network that monitors soil temperature, and soil moisture at 
+189 locations in different depths (5, 20 and 50 cm) throughout the study 
+site. Periodically also different chamber measurements were made to access 
+soil or plant gas exchange. Soil water content was determined using the 
+wireless sensor network SoilNet (Bogena et al., 2010) in 15 minute intervals 
+at 87 locations within the southern part of catchment. The SPADE soil water 
+content sensors (Hübner et al., 2009; Qu et al., 2013) were installed at 
+5 cm, 20 cm and 50 cm depth along a vertical profile. In order to increase 
+the measurement volume and to allow examination of inconsistencies in sensor 
+output (e.g. due to imperfect contact of sensors with the soil matrix), two 
+sensors were installed in parallel at each depth with a distance of ~8 cm. 
+Soil water content measurements outside the physical plausibility range 
+(0.05 to 0.85 cm3cm-3) caused by temporary sensor failure or reduced current 
+supply were identified and flagged. The same was done for soil temperature 
+(-5 and 30 Â°C). Unreliable measurements were identified and flagged based 
+on the continuity of the time series data. For this, the first derivative 
+of the soil water content time series was used. If the increase in soil 
+water content at a particular time step was larger than two times the 
+standard deviations of the soil water content measurements in the preceding 
+24 hours, the soil water content measurement was identified and flagged as 
+an unreliable measurement. All the data from the wireless sensor network 
+were visualized to identify the performance of this automatic flagging 
+method. <br />
