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 ObservatoriesDeveloping generic analysis tools
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

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)

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

ConclusionsAMDA 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.

If you use AMDA or CDPP services for publications, please aknowledge
If someone is interested, an interactive demo can be performed in the poster room after the session.
