Updated 2019 January 15

Correction of several typos and update of AMDA windows

Goals

  • Hands on LATMOS simulation database and Visualization tools (AMDA, 3Dview, TopCat)
  • Comparison between MGS observations and Hybrid simulation results

Steps

Presentation of LatHyS

1

Choosing one Martian simulation :
LatHyS catalog propose the main characteristic of the simulation - The ResourceID (Name) :

LatHyS_Mars-18_01_13@...

  • IMF values : (-1.63, 2.52, 0.0) nT
  • Sub Solar Longitude : 0 degree (main crustal field on the nightside)

Searching if MGS data have similar IMF values ....

2

Comparison between MGS observations and Hybrid simulation results using AMDA

3

Use Data Mining tool (Magnifying glass)
Enter a data Mining condition by dragging and dropping resources of the workspace explorer (MGS bx_mso => data mining conditions)
The condition mark out the simulation IMF value : -2<Bx<-1 , 2<By<3, -1<Bz<1
Specify a sampling time (averaging over 300s), the name of the request and the Time interval Start Time : 1998/07/05 => Stop Time : 1998/07/15
Then perform the search...

4

Visualize the Time Table created from the search and manipulate it in order to have about one orbit per event

  • Extend all time periods by 360 min (6h) and shift them by -180 min (3h) to have new periods of about 6h centered on your searched time results
  • Name your Time Table (Mars_SW_Region)

Create a new parameter corresponding to the Total B field (MGS) Idem by drag and drop

Visualize your data with the plotting data function. Select each component of the MGS magnetic field (MSO) with some color code (bx : blue, by:green, bz : red, btot from derived parameter : orange) + MGS ephemeris (xyz_mso in CYL coordinate system)
For Time Selection : select Time Table and drag and drop the Mars_SW_Region from My_Time_Table

6 7 8

Add simulation result datasets:
Remote data(Simulations)/MODELS@LATMOS/LatHyS_Mars_18_01_13/Magnetic_field

Drag and drop each B component and select MGS S/C

Possibility to zoom
