Discussion items

TopicWhoNotes
Baptiste Cecconi
  • IMPEx (Integrated Medium for Planetary Exploration) http://impex-fp7.oeaw.ac.at/
    • Plasma and magnetic environment for planets
    • Selection, download, visualization and analysis
    • Compare simulation with observation (in reverse way)
    • Tools
      • AMDA, 3Dview, CLWeb, IMPEx Portal
    • Features: 
      • extendable
      • standards
      • as generic as possible
      • web based
  • Data Model for IMPEx
    • data model for plasma simulations
    • based on SPASE (data model for observational plasma data)
    • IMPEx-DM is based on SPASE 2.2.2. And IMPEx-DM is now included as an extension of SPASE on SPASE web site. Current versions: SPASE-2.2.9 and IMPEx-1.3. 
    • Main component:
      • SimulationModel: code description [Instrument]
      • SimulationRun: parameters of a SimulationModel run [observation mode]
      • NumericalOutput: 1 per type of SimulationRun output product
      • Granule: 1 per output element (file, URL…) within a NumericalOutput
  • IMPEx Configuration 
    • IMPEx configuration: XML with provider descriptors. 
    • tree.xml (for data product); methods.xml (for webservices)
  • IMPEx Protocol 
    • 28 methods. Core = 3 methods (implemented in 3Dview):
      • getDataPointValue
      • getDataPointValueSpacecraft
      • getDataPointSpectra
    • Uses SAMP
  • IMPEx technical information: http://impex-fp7.oeaw.ac.at/documentation.html
  • IMPEx Portal web ste: http://impex-portal.oeaw.ac.at/#/portal
  • IMPEx API view: http://impex-portal.oeaw.ac.at/api-view
  • Latest released SPASE/IMPEx schema: http://www.spase-group.org/data/schema/spase-sim-1_0_0.xsd
LatHyS@LATMOS
CCMC@CDPP
TRANSPLANET@IRAPVincent Génot
MPI-AMRVAC@LESIALéa Griton
  • Developed in Belgium a long time ago for MHD
  • adapted for Mercury case
    • Preparation for BepiColombo/MMO
    • theoretical studies for propagation of waves around mercury
  • adapted for fast rotators
    • no codes really available for this, for instance in the case of Uranus
    • 3D spherical grid, adaptive meshing (could be automatic where steep gradient)
  • First draft example tree for MPI-AMRVAC: tree_LESIA_Filippo.xml
MDISC@UCL
  • Magnetodisc model, with solar wind input.
    • Polar coordinates
  • prototyping in 3Dview:
    • Initial file are in netCDF display into 3Dview (small routine inside 3Dview written by Laurent Beigbeder)
    • In 3Dview IMPEx/2Dcuts are expected to be provided in VOTable
  • IMPEx tree : http://astroweb.projects.phys.ucl.ac.uk/models/mdisc/impex/mdisc.xml
  • First test to display MDISC data into 3Dview from IMPEx tree was successful.
    • local IMPEx configuration in 3Dview:
    • Selection of IMPEx product in 3Dview:
    • Displaying selected product in scene:


  • Update on DaCHS server at UCL:
    • There was still problems with the access and web redirections.
    • Server was upgraded to latest beta version (change in /etc/apt/sources.list)
    • GAVO configuration file (/etc/gavo.rc) was also updated with the following section

      [web]
      bindAddress:
      serverPort: 8000
      serverURL: http://astroweb.projects.phys.ucl.ac.uk:8000

      Note the the port number is present twice. This appears to be necessary for the system to work properly.

    • The mdisc/q.rd resource descriptor was also updated to use the latest epntap2.rd mixin definition file, as fixed during the VESPA implementation workshop of Graz.
    • The use of a csvGrammar was discussed but not yet implemented.
VOISE@UCLPatrick Guio, Cyril Chauvin, Renaud Savalle
  • SAMP input:
    • Some time was dedicated to try to setup a SAMP input connection for VOISE.
    • Installation of SAMP library is done. Retrieval of input URL through SAMP is working. Help from Renaud Savalle and Cyril Chauvin was greatly appreciated.
    • Issues with the Django / Apache server on UCL side prevented finalizing this task. This should not be too difficult, but that will be a follow up activity.
  • Results:
    • Currently the VOISE results are sent by email. Usually very big files (>10MB, and even several 100MB...), so the emails are not sent to the requester.
    • We could try to plan to modify this result distribution scheme to provide a link to data to be downloaded within a predefined period of time. This requires updating the Django code. We have to decide if it's worth investing into this (mostly time from PADC to help Patrick Guio).

Next steps
  • Organize a next workshop (2 days) in late May or early June, in Paris: include UCL, CDPP, PADC and LESIA.
    • During that workshop, propose a seminar to PADC and/or LESIA-modelling-and-simulation-group
    • Invite Sébastien Hess to the next workshop
  • Pierre Le Sidaner to finalize ASCII→VOTable script. 
    • Need GROUP and FIELDref for definition of Reference Frame in use in VOTable
  • Pierre Le Sidaner, Cyril Chauvin: see if LatHyS tree.xml explorer can be reused and proposed on a standalone server for testing and visualizing IMPEx XML trees.
