What is envisioned at CESR and CDPP

Mirror site of the THEMIS space data:Relay for distributing the THEMIS space dataBackup of THEMIS space data

AMDA: service for Automated Multi-Dataset AnalysisHelp for event searchHelp for event characterisation and statistics

CL: software for integrated detailed analysis of THEMIS/CLUSTER (and others) data

Automated Mutiple Dataset Analysis / Space Physics

AMDA / SP: the goals

Multiple Dataset: the study of the (multi-scale) dynamics of plasma objects requires to perform the integrated analysis of multi-point and multi-instrument data

Automated (or semi-automated) Analysis: help forSearch, characterisation, classification of events Extensive exploitation of the vast database (statistics)“historical” studies (example: through solar cycles)Building cataloguesBuilding virtual constellations

AMDA, fact sheet

• Now, very first prototype (construction started in June 2006 after kind of phase-A)

• Built on an existing data system (DD_System, A. Fedorov)

• Built in IDL, C, FORTRAN, Javascript

• Works on standardised and “simple” data, NetCDF

• Includes models (Tsyganenko, Shock, MP, NS, …)

• Attempt for using web-services of CDAWeb and the up-coming VxOs

• Forum for user feedback

• Already in use for scientific studies

Automated and semi-automated search

Sub-dataset conditional extraction

Distant access to complementary data

An example: search of the events when the cross-tail current is “encircled” by CLUSTER

Test:• X1< -10 Re • BX1 * BX2 * BX3 * BX4 > 0• min([BX1 BX2 BX3 BX4]) < 0• max([BX1 BX2 BX3 BX4]) > 0

Looking for the time periods when 2 s/c are above the neutral sheet and the 2 other ones are below

Looking for possible X-line with a pair of spacecraft

BZ1 * BZ2 < 0 ANDVX1 * VX2 < 0 ANDBX1/Blob < 0.5 AND BX2/Blob < 0.5

CLSoftware for detailed analysis

High level products:-distribution function-spectrograms in PA, 1/V-partial moments

Remote running

Conclusion: what can be done at CESR and CDPP for the THEMIS community?

Mirror site for space THEMIS data

Distributing CL, but limited user help

Remote running of CL on dedicated machine(s)

AMDA for event search, catalogue building, statistics on “simple” THEMIS and complementary data

Coupling AMDA event search and CL (and any other softwares or system: CDAWeb, UCB, …) by exporting time-tables

Some examples:AMDA + CL (or other softwares):1) Users produces time-tables on AMDA based on their own

defined criteria applied on the content of the data they selected2) Time-tables sent to CL3) Users browse user-defined plots on the periods of the time-

tables and then run detailed analysis on CL

SSCWeb + AMDA:1) Users produces time-tables on SSCWeb based on criteria

applied on the orbitography and conjonctions.2) Time-tables sent to AMDA3) Users produces secondary time-tables on AMDA based on

criteria applied on the content of the data for the periods of SSCWeb time-tables

4) Then, these secondary time-tables are exported to detailed analysis softwares or are used inside AMDA for building catalogues, or …
