Abstract. The Rollesbroich headwater catchment located in western Germany is a densely instrumented hydrological observatory and part of the TERENO (Terrestrial Environmental Observatories) initiative. The measurements acquired in this observatory present a comprehensive data set that contains key hydrological fluxes in addition to important hydrological states and properties. Meteorological data (i.e., precipitation, air temperature, air humidity, radiation components, and wind speed) are continuously recorded and actual evapotranspiration is measured using the eddy covariance technique. Runoff is measured at the catchment outlet with a gauging station. In addition, spatiotemporal variations in soil water content and temperature are measured at high resolution with a wireless sensor network (SoilNet). Soil physical properties were determined using standard laboratory procedures from samples taken at a large number of locations in the catchment. This comprehensive data set can be used to validate remote sensing retrievals and hydrological models, to improve the understanding of spatial temporal dynamics of soil water content, to optimize data assimilation and inverse techniques for hydrological models, and to develop upscaling and downscaling procedures of soil water content information. The complete data set is freely available online (http://www.tereno.net, doi:10.5880/ TERENO.2016.001, doi:10.5880/TERENO.2016.004, doi:10.5880/TERENO.2016 and additionally referenced by three persistent identifiers securing the long-term data and metadata availability.

“…Each TERENO observatory is responsible for the organization and storage of its own data, but interlinked using standardized interfaces within a distributed data infrastructure (Kunkel et al, 2013, Koldiz et al, 2012. During instrumentation of the four terrestrial observatories, local data infrastructures were implemented by the TERENO partners (Figure 3).…”

“…An Observation Data Model was developed to represent the processes of data recording, import and publication adequately. It contains several components, which allow for detailed characterization of the data values, sites and variables, used sensors, configuration of the individual input files, transformation and averaging procedures, responsible parties, sample specifications and publishing information (Kunkel et al, 2013). Almost all data are accessible freely as soon as quality assessment of the data was performed set.…”

Central elements of the TERENO network are “terrestrial observatories” at the catchment scale which were selected in climate sensitive regions of Germany for the regional analyses of climate change impacts. Within these observatories small scale research facilities and test areas are placed in order to accomplish energy, water, carbon and nutrient process studies across the different compartments of the terrestrial environment. Following a hierarchical scaling approach (point-plot-field) these detailed information and the gained knowledge will be transferred to the regional scale using integrated modelling approaches. Furthermore, existing research stations are enhanced and embedded within the observatories. In addition, mobile measurement platforms enable monitoring of dynamic processes at the local scale up to the determination of spatial pattern at the regional scale are applied within TERENO.

“…Data and metadata are stored in a PostGIS database, and are accessible via OGC-compliant web-services. The TEODOOR web portal (http://teodoor.icg.kfa-juelich.de) consumes the services, and acts as a front-end that supports data discovery, visualization and download [29]. Observation data from the rest TERENO observatories can also be discovered via the same portal.…”

The worldwide Sensor Web comprises observation data from diverse sources. Each data provider may process and assess datasets differently before making them available online. This information is often invisible to end users. Therefore, publishing observation data with quality descriptions is vital as it helps users to assess the suitability of data for their applications. It is also important to capture contextual information concerning data quality such as provenance to trace back incorrect data to its origins. In the Open Geospatial Consortium (OGC)'s Sensor Web Enablement (SWE) framework, there is no sufficiently and practically applicable approach how these aspects can be systematically represented and made accessible. This paper presents Q-SOS-an extension of the OGC's Sensor Observation Service (SOS) that supports retrieval of observation data together with quality descriptions. These descriptions are represented in an observation data model covering various aspects of data quality assessment. The service and the data model have been developed based on open standards and open source tools, and are productively being used to share observation data from the TERENO observatory infrastructure. We discuss the advantages of deploying the presented solutions from data provider and consumer viewpoints. Enhancements applied to the related open-source developments are also introduced.
