  1. Plasma Node: Use Case Analysis C. Jacquey, N. André, M. Gangloff, R. Hitier, E. Pallier,E. Budnik, V. Génot, B. Cecconi, C. Harvey, CDPP/CESR, Toulouse F. Topf, H. Rucker, M. Khodachenko , IWF, Graz Frascati, EuroPLANET N7 meeting, October 9, 2007

  2. Challenges of IDIS/plasma node:components of the problem Study types: • Case studies • Statistical/systematical studies • Simulation • Theory Fields • Plasma • Comparative studies • Heliophysics studies • Global (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 • the Big Challenge… • and a strong justification of a planetary VO

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

  4. Goals of the Europlanet/N7 action in FP6? • (1) Inventory of the resources (until what level?) • (2) Science cases: Identifying user requirements and scientific specifications • (3) From them, recommending specifications on: • Data • Services • Tools • Models Description, exchange, exploitation • Final product: reference document, basis for the FP7 proposal • (4) Build demonstrators/experimentators: to be applied to use cases  Preparing the FP7 Europlanet project

  5. 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 FP6/N7 • In pratice, in regards of the user requirements: • Are SPASE, IVOA or PDS good basis? • Which one – or combination - is the most adapted? • Recommendations for FP7 project?

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

  7. Application: science case “Solar wind / saturn magnetosphere interaction and auroras” (1) Needed resources • In situ data • CASSINI B-field, plasma, particles • Heliospheric (ACE, WIND, ULYSSES, MEX) B-field, plasma, particles • Remote data • Solar observations • CASSINI, ULYSSES radio • CASSINI aurora images • HST, FUSE saturn aurora images • Services • 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

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

  9. Needed extensions on SPASE • Spacecraft attitude does not exist in SPASE (yet) • Instrument attitude does not exist in SPASE (yet) • Field of view of instrument does not exist in SPASE (yet) But it is possible to implement extensions.

  12. Prototypes.demonstrators • Registry demonstrator: (Demo if extra time) • Description SPASE of several planetary plasma data (MAPSKP, VEX, MEX) • Building a registry • Building a search engine • Goals: demonstration and experimentation (standard versus user requirements, SPASE extensions, …) • Science demonstrator: (Demo if extra time) • Based on AMDA • Using distant data (MAPSKP, VEX-MAG, HST) and local data • High level tools and functionalities • Goals: demonstration and experimentation

  14. AMDA, Automated Multi-Dataset Analysis (http://cdpp-amda.cesr.fr) • Multi-spacecraft and multi-instrument data • Visualisation • user defined parameter computation • Standard model computation • Data and computed parameter extraction • Event list production and management • Automated and semi-automated (visual) search on the content of the data • Access to external databases (now: CDAWeb, CDPP, next: MAPSKP, VEX-MAG, HST images, MEDOC solar data, …) MAPSKP AMDA CDPP System CDAWeb Local Database

  15. Prototype application on use cases Request of resource location Registry prototype Searching the resource location (MAPSKP, HST aurora, VEX, ACE) Local database MAPSKP USER AMDA/Planeto Science prototype Access, extraction of the targeted data (distant or local) Integrated analysis VEX-MAG Graz HST

  16. IDIS external connections • IDIS requests to outside: • Astronomy (IVOA), HST, XMM, Ground radio-astronomy (Nancay, LOFAR) • Plasma solar system (heliophysics): Heliophysics VO (ULYSSES Jupiter flyby), HELIO, EGSO, Radio-planetology (ULYSSES) • Spectroscopy database • Outside resource requests to IDIS: • Earth magnetosphere studies: ROSETTA, CASSINI or GALILEO earth fly-by • Heliophysics Vos: Planetary probes used as solar wind monitors

  17. Conclusion • What can be done shortly (2 months): • User requirement reference document for plasma field • Analysis of existing standards et sub-sequent recommendations for FP7 but need help for IVOA (CDS, ASOV) and PDS • SPASE based registry demonstrator for some planetary plasma resources • Specification of communication with external VOs (for the plasma field) And for February 15, 2008: • User requirement reference document for inter-thematic (inter-node) fields, i.e., more science cases to be analysed • Requirements on the inter-node data model, recommendation for the future IDIS • Science demonstrator, V1.0, (MAPSKP, HST, VEX, MEX)

  29. Use case analysis • Goals: • Specify/recommend the content of the data model • Specify/recommend an architecture • Global method: First a prototype study for validating the method. • (1) Extracting user requirements from use case analysis • • Formulating the results • (2) Defining an information system (data model + architecture) • (3) Scenarii for performing the user studies using the defined system and identifying the inconsistencies, bugs, etc… • Then, iterating (2) and (3) • Practical approach: - (i) starting from SPASE and see what it is needed and missing - (ii) the same for IVOA, (iii) and PDS? • Recommendation

  30. Starting point Prototype use case: ■ EuroPLANET selected use case: Campaign in 2004 (or 2006, 2007) approach of CASSINI toward Saturn CASSINI data, HST images (external from IDIS or atmosphere node?), models, … ■ The R.
