GEOWOW Enhancements for Weather Forecasting and River Discharge Data GEO-X Plenary & Ministerial Summit Geneva, 14 January 2014 Dr. Simon Jirka 52°North GmbH with contributions from GEOWOW partners
GEOWOW Overview GEO Ministerial 2014: ‘Evolved' architecture properly tested and demonstrated within GEOWOW SBA's
Main Objectives • GEOSS Infrastructure Evolution for all stakeholders (with a particular focus on the Weather/Ocean/Water SBAs): • To facilitate discovery, access and use of … • Data • Other GEO-resources • To allow harmonised access to heterogeneous resources • To promote and simplify data sharing • Particular focus on the GEOSS Data CORE
Use Case: River Discharge • The evolutions proposed by GEOWOW are evaluated via concrete use cases. For example: • “Modeling of river discharge using weather predictions and validation based on river discharge observations”
Showcase Components Discharge prediction • Modellingriver discharge using the THORPEX Interactive Grand Global Ensemble (TIGGE) archive ECMWF Discharge observations • Calibrating and validating model outputs using river discharge observations from the Global Runoff Data Centre (GRDC) 9000 stations Visualisation/Assessment • Exchanging and assessing observed and predicted data using international standards (SOS 2.0/WaterML 2.0) and new functionalities of the GCI
New Functionalities for the GCI • Development of software components (server/client) implementing the proposed hydrology profile of the SOS 2.0 standard • Utilizing Web clients to allow the user to visualize, compare and assess hydrological time series (observed and ensemble data) • Integration of the software solutions as new hydrological data services into the GEO Discovery and Access Broker
International Standardization • The OGC Sensor Observation Service Interface Standard (SOS 2.0) is a domain independent core standard of the OGC Sensor Web Enablement framework • Provides an interface for exchanging sensor data and metadata • In cooperation with the Hydrology Domain Working Group, GEOWOW developed a Hydrology Profile for OGC SOS 2.0 specification • Optimized interface to access WaterML 2.0 encoded hydrological time series data • Documented in „SOS 2.0 Profile for the Hydrology Domain“ • Planned to improve to an OGC Best Practice Paper
Showcase Overview Hydrology SOS 2.0 Hydrology SOS 2.0 TIGGE Meteorological Data River Discharge Modelling Calibration, Validation & Recalibration Model results sufficient GRDC River Discharge Data GCI Broker User interface: Visualization of predicted and observed data
Implementation Architecture Hydrological applications • GRDC • Oracle database • SOS implementations by 52°North and KISTERS • ECMWF • PostgreSQL database • 52°North SOS • No WSS Database GCI Broker SOS Connector GRDC/ECMWFNetwork O&M 2.0/ WaterML2.0 WSS SOS GRDC/ECMWF Server WSS = 52°NorthWeb Security Service
Demo A hydrologist searches for riverdischarge data sets for a specific station or region and for a specific timeframe:
Demo The search result comprises predicted river discharge time series data sets...
Demo … and observed river discharge time series data sets.
Demo For each time series metadata can be accessed:
Demo Metadata sheet:
Demo Data sets can be directly downloaded from a SOS 2.0 server (WaterML 2.0):
Demo Also a link to a Web-based viewer is offered:
Demo The client allows to visualize time series data, e. g. an observed hydrograph (GRDC): Add time series
Demo The user can select additional time series via the client, e.g. modelled data: Choosedatasource
Demo Or directly via the GEO DAB:
Demo This allows comparing and assessing observedandpredicted time series: Add time series
Summary • Data sets made accessible: GEOWOW • Integrates the TIGGE archive into the GEOSS Common Infrastructure • Contributes river discharge data (GRDC) to the GEOSS Data-CORE • Hydrology Profile of the OGC SOS 2.0 • New multi-disciplinary functionalities for the GCI • Discovery • Access • Analysis of hydrological data • Sensor Web Client as an interactive platform for visualisation • Improved GCI for an interoperable global exchange of hydrological data
