Abstract
Abstract. Long-term monitoring of water resources and climate parameters at the scale of river basins requires networks of continuously operated in-situ stations. Since 2009, GFZ and CAIAG, in cooperation with the National Hydrometeorological Services (NHMS) of Central Asia, are establishing such a regional monitoring network in Kazakhstan, Kyrgyzstan, Tajikistan, Uzbekistan, and lately Afghanistan to collect observations of meteorological and hydrological parameters and to deliver them to the end-users for operational tasks and scientific studies. The newly developed and installed remotely operated multi-parameter stations (ROMPS) do not only monitor standard meteorological and hydrological parameters, but also deliver Global Navigation Satellite System (GNSS) data for atmospheric sounding as well as tectonic studies. Additionally, three stations integrate seismic sensors for earthquake monitoring. The observational data from the ROMPS is transmitted nominally in near-real time, but at least once a day to a centralized geo-database infrastructure for long-term storage and data redistribution. Users can access the data manually using a web-interface or automatically using SOS requests; in addition, data is planed to be distributed to the NHMS through standard communication and data exchange channels.

Summary
All ROMPS are operated and managed by several software components and scripts (Fig. 4) running on the PC module (see Sect. 2.1). Multi-sensor stations like ROMPS with their different types of data streams require higher bandwidth, real-time access and a two-way communication lines. The System Operation, Processing and Archiving Facility (SOPAF) is the central IT-platform of the CAWa monitoring network and serves to collect, process, and archive all information delivered by the ROMPS As such it integrates information obtained from heterogeneous information resources as well as to support the integration of various data types such as meteorological, hydrological, GNSS or seismic data. – the ability to communicate with existing monitoring networks (e.g., those operated by the national Hydrometeorological Services) using standard exchange protocols This requirement enables users to integrate requests to SOPAF into their operational standard procedures. As the TSB, SOPAF is acting as an integration platform providing interfaces and services for the access to sensor data following the SWE standards like the Sensor Observation Service (SOS) (SOS, 2007)
