Couple satellite sensor web service with WRF model for weather decision service

Nowadays, the Sensor Web provides a new way for sensor planning and observation service, whereas, how to couple diverse satellite observations with specified forecast model for weather support decision service under Sensor Web environment is a big challenge. This paper proposes a new framework for put data assimilation into a forecast model. The framework is realized based on the Sensor Web Enablement (SWE), Business Process Execution Language (BPEL) and Web Processing Service (WPS) under the Service Oriented Architecture (SOA) and Open Geospatial Consortium (OGC) standard. The framework contains four main Service components: Sensor Observation Service (SOS), Sensor Alert Service (SAS), Web Notice Service (WNS) and WPS. All the services are chained with BPEL and could be automatically executed. The processing framework is distributed, interoperable, plug-and-play and automatically.
