Some aspects of space physics studies · need to analyse measurements obtained by several observatories We · need to analyse multi-instrument data We · need to compare the observations to simulation results We · 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
AMDA Automated Mutiple Dataset Analysis ØWeb based service ØTransparent (automated) access to data the user plays with parameters, not with files ØAMDA local database (CLUSTER, ACE, THEMIS, GEOTAIL, WIND, …, STEREO, VEX, MEX, …, IMP-8, ISEE, … geomagnetic indices) ØExternal databases (CDAWeb, CASSINI: MAPSKP+SKR, VEX-MAG, THEMIS/CESR, …) ØProduces and exploits time-tables and catalogues !

Science Case: study and characterisation of the local properties of the cross-tail current Ø 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) … Ø Influence factors: (i) Solar Wind pressure (ii) IMF (iii) Geomagnetic activity: - State of the ionosphere. - Oxygen abundance - Ring current intensity
