Digital Earth Communities 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

Digital Earth Communities Use Case: River Discharge “Modeling of river discharge using weather predictions and validation based on river discharge observations” The evolutions proposed by GEOWOW are evaluated via concrete use cases. For example:

Digital Earth Communities Showcase Components Modelling river 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 Discharge prediction

Digital Earth Communities 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

Digital Earth Communities 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

Digital Earth Communities A hydrologist searches for river discharge data sets for a specific station or region and for a specific timeframe: Demo

Digital Earth Communities The search result comprises predicted river discharge time series data sets... Demo

Digital Earth Communities … and observed river discharge time series data sets. Demo

Digital Earth Communities For each time series metadata can be accessed: Demo

Digital Earth Communities Metadata sheet: Demo

Digital Earth Communities Data sets can be directly downloaded from a SOS 2.0 server (WaterML 2.0): Demo

Digital Earth Communities Also a link to a Web-based viewer is offered: Demo

Digital Earth Communities The client allows to visualize time series data, e. g. an observed hydrograph (GRDC): Demo Add time series

Digital Earth Communities Demo The user can select additional time series via the client, e.g. modelled data: Choose data source

Digital Earth Communities Demo Or directly via the GEO DAB:

Digital Earth Communities Demo This allows comparing and assessing observed and predicted time series: Add time series

Digital Earth Communities 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
