| Zusammenfassung |
| The European Commission funded the European Cluster Assimilation Techniques
(ECLAT) project as a collaboration of five leading European universities and research
institutes. A main contribution of the Finnish Meteorological Institute (FMI) is
to provide global MHD runs with the Grand Unified Magnetosphere Ionosphere
Coupling simulation (GUMICS) based on one year real solar wind data. Solar wind
magnetic field, density, temperature and velocity data are downloaded from the
OMNIWeb open database and a special input file is created for each Cluster orbit.
The Cluster orbits are divided into 12 slices allowing parallel computation and
each slice has an average tilt angle and IMF Bx. Each simulation starts one hour
before the Cluster perigee to provide time for building up a magnetosphere in the
simulation space and all simulation results are saved every 5 minutes (in physical
time).
Certain parameters (temperature, density, velocity, magnetic field etc.) are dumped in the
simulation space along the Cluster spacecraft orbit. Quickplots are created from GUMICS
ionosphere and magnetosphere simulations. The ionospheric footprints of Cluster spacecraft
are determined from observations and dynamic simulations. The results of the two different
methods are compared for several selected events. All products will be available at the
Cluster Active Archive soon. |
