MCGM (v.04)

Magnetic Clouds Global Model

Model Description

Tool for the analysis of magnetic clouds, based on a non-force-free magnetic topology. Fitting the main physical magnitudes, including those related to plasma behavior, one can obtain the parameters associated with the magnetic cloud axis orientation.
Torus topology with circular cross-section with maximum variable radius along it.

Model Inputs Description

Magnetic Field, and Plasma data from CDAweb in requested periods.
Magnetic Field components (RTN or GSE), Plasma Beta (Solar wind speed, Proton density, Temperature, Plasma Pressure).

Model Outputs Description

Graphics for:
•	RTN or GSE and Total Magnetic Field components (intensity),
•	 Solar Wind speed, 
•	Proton density, 
•	Temperature, 
•	Pressure, 
•	Plasma Beta (see attached examples)
•	Boundaries of the selected magnetic clouds for the studied phenomena


From the fitting of the model the parameters obtained:
•	Longitudinal angle axis in ecliptic plane
•	Latitudinal angle axis over the ecliptic plane.
•	Closest distance of approach of the spacecraft trajectory to the MC
•	Helicity of the cloud.
•	Fitted Magnetic Field components

Model Caveats

Change Log

Fitting of the Magnetic Field components. In a fore coming version the Plasma Pressure, Density Current and Electric Field will be implemented.
