WIS Enablers, Geneva 2010 - 3© ECMWF ECMWF: Objectives Operational forecasting up to 15 days ahead (including waves) R & D activities in forecast modelling Data archiving and related services Operational forecasts for the coming month and season Advanced NWP training Provision of supercomputer resources Assistance to WMO programmes Management of Regional Meteorological Data Communications Network (RMDCN)

4. WIS Enablers, Geneva 2010 - 4© ECMWF Dealing with large amount of multi-dimensional data

5. WIS Enablers, Geneva 2010 - 5© ECMWF Dealing with large amount of multi-dimensional data (cont.) Forecasts run several time a day, providing regular update of the possible future

6. WIS Enablers, Geneva 2010 - 6© ECMWF Dealing with large amount of multi-dimensional data (cont.) Each model grid point represent hundreds of meteorological variables: temperature, pressure, precipitations, … The atmosphere is split vertically into many levels

7. WIS Enablers, Geneva 2010 - 7© ECMWF Dealing with large amount of multi-dimensional data (cont.) Ensemble Forecasts: capturing the chaotic nature of the atmosphere Forecast many equally possible futures Forecast time Temperature Initial condition Forecast

8. WIS Enablers, Geneva 2010 - 8© ECMWF Dealing with large amount of multi-dimensional data (cont.) Meteorological data is multi-dimensional – 3 dimensions of space – 2 dimensions of time (analysis time, forecast time) … and many more for ensemble prediction systems (many possible futures) – 100s of variables (Temperature, Wind, Clouds, Humidity,…) – many different models Short range, Medium range, Monthly, Seasonal, … Global, Limited area From several NWP centres around the world Current web interfaces are limited to: – 2 space dimensions (screen) – 1 time dimension (animation) – 4 colour dimensions (red, green, blue and transparency)

9. WIS Enablers, Geneva 2010 - 9© ECMWF Dealing with large amount of multi-dimensional data (cont.) Make full use of available graphical tools – Layering – Colour, transparency, symbols – Animations – Re-projections Provide statistical analysis tools – Means, probabilities, clustering, … – Time series, cross-sections, … Give the user full control over these tools – … so they can choose what suit their current workflow – Requires the ability to run these tools on-demand, based on user input, in a reasonable time (e.g. <10s)

10. WIS Enablers, Geneva 2010 - 10© ECMWF 10 ECMWF Web re-engineering project: Motivations – Increasing use by our supporting states and many commercial customers of our web products Demand for a high availability service – Users request more tailored products Requires on-demand plot production Goals – Redesign the web infrastructure so that the web service is highly available – Provide more interactivity (e.g. zoom, pan, overlay parameters) – Allow product customisation (e.g. control the event threshold on probability maps) – Use open (OGC) standards so that ECMWF products can be embedded in users own software Aimed directly at our Member States forecasters and commercial customers

11. WIS Enablers, Geneva 2010 - 11© ECMWF 11 Gathering of user requirements The project has been presented on several occasions Consultation process will continue throughout the project Focus on usability

12. WIS Enablers, Geneva 2010 - 12© ECMWF 12 Application 1: Web based forecasting tool Fully Interactive: – zooming, panning, … – animations Customisation: – Probabilities threshold, … – Show/hide, add/remove layers Associated tools: e.g. meteograms For expert users (forecasters)

13. WIS Enablers, Geneva 2010 - 13© ECMWF 13 Application 2: Product catalogue Browsable and searchable graphical product catalogue Limited interactivity – Preset number of projections, animation Intended to be used by a wider audience

14. WIS Enablers, Geneva 2010 - 14© ECMWF 14 So that ECMWF products can be directly embedded in the forecasters workstations application All products accessible via WMS protocol: – GetCapabilities document build dynamically from product catalogue content – Layers are created on-demand Challenges: - access control - time dimension - customisation Application 3: OGC Web Map Services
