2. The CDPP (http://cdpp.cesr.fr)  French national centre (CNRS-CNES) > 10 years  Hosted at CESR, Toulouse, France  Missions: -Archiving the data for long-term preservation -Valorisation of the data ·Making data easy to use ·Providing tools and services -Participation to Virtual Observatories

5. Some aspects of space physics studies ·We need to analyse measurements obtained by several observatories ·We need to analyse multi-instrument data ·We need to compare the observations to simulation results ·Creating Time-Tables (or event list) and catalogues is a common step of the work We need to extract and treat a lot of data coming from multiple resources  This takes time and energy %Building Virtual Observatories %Developing generic analysis tools

6. AMDA Automated Mutiple Dataset Analysis  Web based service  Transparent (automated) access to data  the user plays with parameters, not with files  AMDA local database (CLUSTER, ACE, THEMIS, GEOTAIL, WIND, …, STEREO, VEX, MEX, …, IMP-8, ISEE, … geomagnetic indices)  External databases (CDAWeb, CASSINI: MAPSKP+SKR, VEX-MAG, THEMIS/CESR, …)  Produces and exploits time-tables and catalogues Visualisation editor Parameter editor Download data Conditional search External data Visual search Time-Table manager AMDA DOES NOT WORK FULLY WITH InternetExplorer and Safari AMDA is public (registred or guess users, at http://cdpp-amda.cesr.fr) !

7. Science Case: study and characterisation of the local properties of the cross-tail current  Based on CLUSTER data when it encircles the neutral sheet. (i)Current density, profile, gradient (ii)Thickness, location, motion (iii)Distribution function (i+ and e-), flows, … (iv)Turbulence/wave level and spectra (v)…  Influence factors: (i)Solar Wind pressure (ii)IMF (iii) Geomagnetic activity: -State of the ionosphere. -Oxygen abundance -Ring current intensity

18. Conclusions %AMDA is a web based service, continuously developed with the support of CNES and CNRS %AMDA is public (guest or registred user) %AMDA: Visualisation, data download, parameter computation, visual search, automated conditional search, time-table managment ÞAutomated recognition, proxy studies, creating catalogues … ÞShould be useful for space weather studies %AMDA is VO (SPASE based) compliant %AMDA in european VO projects: EuroPLANET/IDIS, HELIO, TTE %Feedback from user is very welcome.
