  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

  3. August 15, 2007 Messenger MEX ejecta VEX STEREO A and B Compressed solar wind shock Energetic particles Ulysses Around the Earth: ACE, WIND THEMIS, CLUSTER, GEOTAIL, … Ex.: Prangé et al., Nature, 2004

  4. 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

  5. AMDA Automated Mutiple Dataset Analysis Visualisation editor • 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 Download data Parameter editor External data Conditional search 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)

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

  10. Conditional search

  11. Managing Time-Tables

  12. Parameter computation

  13. Data download On the fly data merging

  14. Access to external databases

  15. VO: AMDA SPASE compliant MAPSKP AMDA SKR System Local Database CDAWeb Any databases including a SPASE based interoperability layer can be used by AMDA

  16. VO: a collaboration based on Time-Table Exchange Time-Tables Other? CDAWeb DARTS Other? CDPP/CESR THEMIS database SSL THEMIS database CAA Validated high resolution CLUSTER data • AMDA • Automated search • Visual search •  Time-Tables Time-Tables Data, parameters Data, parameters Standardised sub-databases User tools QSAS CL

  17. Conclusions If someone is interested, an interactive demo can be performed in the poster room after the session. • 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 • Automated recognition, proxy studies, creating catalogues … • Should 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.
