A WGISS GRID based Experiment ? The Virtual Factory Concept Connect several resource center in a WAG Make Process server available Create a virtual distribution scheme Allow the projection by users of needed process Potential partners: Data and GRID providers (Europe+others), Remote job submitter and users (DC representatives ? )

Not Data specific Not Thematic specific Aims at demonstrating the conceptual capability of Virtual services implementation Rely on simple application case and COMPARING conventional and Virtual WAG approaches (including costs elements) Try to identify botlenecking issues and possible needed GRID additions >>Nota: End result is most a fraction of input information !

Get hold of the data (media, access costs, transmission & delays) Process the information Transfert the result to suitable place WAG based concept: Create a "Light" Grid connecting a few centers Make their archive accessible from this GRID Enable the creation of jobs submitted to this GRID =>>Then could be demontrated the feasibility of a virtual factory able to dematerialize the handling of information

Objectives The context of this work package is the strong collaboration with researchers belonging to several university laboratories located in Africa (Ivory Coast, Burkina Faso, Senegal, République Centre Afrique, Bénin and Vietnam..); the African partners having worked in the GIRGEA (Groupe Internationale de Recherches en Géophysique Europe-Afrique) for 10 years. This group has been recently enlarged to Vietnam researchers. The final goal is to provide to scientists from developing countries make use a Wide Aera Grid in order to develop researches in equatorial geophysics. In addition to the experimental data acquisition performed in Africa by the GIRGEA, an empirical equatorial electrojet model has been designed to take into account the observations. This model should now be compared to other related physical parameters, obtained using various instruments.The possibility to translate experimental and theoretical works conducted in Africa into cheap and operational services making use of virtual implementation will be analysed.

CNES, JP ANTIKIDIS, WGISS17 GRID SESSION MAY 2004 Description of work The volume and the quality of the observations are increasing due to global and permanent networks as well as satellites. To carry out geophysical integrated studies, the researchers from developing countries need to combine distributed data bases and large computational resources for addressing the problem of global computations and assimilation of large distributed data sets. Heaven will be an opportunity to provide them such services. The experimental model is based on magnetic measurements carried out continuously along the equator in Africa, Brazil, India and Vietnam. During the International Equatorial Electrojet Year ( ) those networks were extended and a database was constituted. The satellite data has come from the satellite experiment Oersted and Champ. In this first step, the work will consist of describing the software and database in the Virtual context For the second step, other satellite databases will be needed by the different models. These models are time-consuming with large sets of data. After the processing, the data are visualised in 1 or 2 D plots, 3D plots may be used in the second step. Geophysical services will be useful to select the interesting zone and plot the satellite data on the map.
