Petitdidier – 26 September 2006 Enabling Grids for E-sciencE INFSO-RI-031688 4 Earth Science challenges Global, regional, local applications –Alternative use of the data at different time and spatial resolution Large historical distributed archives –Long term data archives to be exploited Near real-time access to data and processing –For value adding and dissemination –For now-casting and alert Models to provide long term trends and forecast –Processing-intensive, data-intensive and complex applications –Data fusion, data assimilation, data mining, modelling … Integrate different data sources –Standardisation, Data policy, … Link data to technical information and scientific results Knowledge platform for ES : the future Grid, an open platform for handling computing resources, data, tools….and a solution for ES Challenges

5. ES applications –EGEE’06 – M. Petitdidier – 26 September 2006 Enabling Grids for E-sciencE INFSO-RI-031688 5 Virtual Organisations VO ESR (Earth Science research) –40 members from 10 countries, belonging to Research institutes, one organisation (ESA) and 2 private companies –Many members are scientists, they port their application, run it, get the results then stop working on Grid to publish and/or write their PhD, including results obtained on EGEE –Private company makes only feasibility test –Access to 30 sites VO EGEODE (Expanding GEOsciences on DEmand ) –Centered on Geocluster: seismic platform developed by CGG, including 400 modules, a license server…. –Dedicated to industry R&D in geosciences and Academic laboratories- many labs already used Geocluster on their machines –More people due to information to academic laboratories for the advantages to use Geocluster on EGEE
