Challenges of IDIS/plasma node: components of the problem Study types: ØCase studies ØStatistical/systematical studies ØSimulation ØTheory Fields ØPlasma ØComparative studies ØHeliophysics studies ØGlobal (inter-nodes) planetary studies Type of ressources (data, services, tools, …): %Plasmas, E-B fields %Neutral (atmosphere, exosphere, other. . ) %Dust, Rings %Small bodies %Planetary surface, volcanism, … %Solar observations %… %Models, simulation codes %Data analysis tools %Data treatment tools % … Two levels: -Intra-node: only dealing with plasma ressources, BUT, interacting with other plasma Vos (HELIO, US-VOs) -Inter-nodes: exchanging ressources with nodes of different thematics Big Challenge… the and a strong justification of a planetary VO

Three main classes of resources (1) Related to pointing instrument (i. e. camera, telescope), remote data Ø Localisation (a, d, R) are the primary parameters Ø e. g. Astronomy IVOA (2) Related to in-situ measurement on dynamical phenomena Ø Time span and region are the primary parameters Ø e. g. Solar Wind data + magnetosphere data SPASE (3) Combining both Ø e. g. , ionosphere, atmosphere dynamics Ø e. g, aurora images Ø e. g. dynamical astrophysics: stellar magnetic field, exoplanets, … IVOA, SPASE

Goals of the Europlanet/N 7 action in FP 6? Ø(1) Inventory of the resources (until what level? ) Ø(2) Science cases: Identifying user requirements and scientific specifications Ø(3) From them, recommending specifications on: Description, exchange, exploitation -Data -Services -Tools -Models %Final product: reference document, basis for the FP 7 proposal Ø(4) Build demonstrators/experimentators: to be applied to use cases Preparing the FP 7 Europlanet project

We do not start from nothing… ■ SPASE ■ IVOA ■ PDS For building a VO, the basis of everything is a standard for describing the ressources, i. e. , - a data (resource) model + a dictionnary - or a model + several dictionnaries - or several [model+dictionary(ies)] + translation tools Defining the specifications on the data model(s) of the future planetology VO is one of the main goal of FP 6/N 7 In pratice, in regards of the user requirements : (i) Are SPASE, IVOA or PDS good basis? (ii) Which one – or combination - is the most adapted? (iii)Recommendations for FP 7 project?

Plasma node: the adopted method for science case analysis User requirement specifications Use case analysis ØAre there blocking points, incompatibilities in the model? ØWhat is missing? ØWhat is not appropriate? ØWhich extensions/modifications could be considered? Confrontation to the existing models: SPASE, IVOA, PDS Modified/extended models Specifications of the IDIS data model Prototypes/ Demonstrators Recommendations for selecting, modifying, extending the existing models – or combining some of them Recommendations for communicating with external VOs

Application: science case “Solar wind / saturn magnetosphere interaction and auroras” (1) Needed resources ØIn situ data -CASSINI B-field, plasma, particles -Heliospheric (ACE, WIND, ULYSSES, MEX) B-field, plasma, particles ØRemote data -Solar observations -CASSINI, ULYSSES radio -CASSINI aurora images -HST, FUSE saturn aurora images ØServices -Integrated analysis tools -Solar wind propagation simulation -Interplanetary disturbance (CME) propagation simulation In red, resources coming from IDIS In blue, resources coming from external VOs

Application: science case “Solar wind / saturn magnetosphere interaction and auroras” (2) Needed resources ØIn situ data -CASSINI B-field, plasma, particles extended-SPASE, (PDS? ) -Heliospheric (ACE, WIND, ULYSSES, MEX) B-field, plasma, particles SPASE ØRemote data -Solar observations SPASE, IVOA -CASSINI, ULYSSES radio extended-SPASE, (PDS? ) -HST, FUSE saturn aurora images IVOA ØServices -integrated analysis tools None -Solar wind propagation simulation in development in SPASE -Interplanetary disturbance (CME) propagation simulation in development in SPASE

Needed extensions on SPASE ØSpacecraft attitude does not exist in SPASE (yet) ØInstrument attitude does not exist in SPASE (yet) ØField of view of instrument does not exist in SPASE (yet) But it is possible to implement extensions.
