Go to EEGGL Tool


EEGGL (Eruptive Event Generator Gibson and Low) is a tool which uses observational data to specify input parameters for the Gibson-Low flux rope model so that it may approximately reproduce observed CME events. EEGGL allows the user to specify the CME source region with the use of synoptic magnetogram data, which in turn provides the location and orientation of the GL flux rope. The observed CME speed provided by StereoCAT tool is used to specify the magnetic field strength of the flux rope.

EEGGL thus aids end-users to employ observational data covering the early phase of an eruption to specify the 3D model of the CME originating in the low corona. The model then allows the propagating of the CME to 1 AU where it makes predictions of the resulting solar wind disturbance.

EEGGL workflow


The original EEGGL program in IDL is developed by the model developers, and the EEGGL web application is developed by the CCMC in partnership with the model developers listed below.


EEGGL is still being improved with revised model parameters so results may vary. Please contact us if results do not match expectations as we strive to improve the model. Contact info of developers is below.

Co-author Statement/Publication Policy
Please follow the CCMC Publication Policy which applies to all models. In addition, published papers using EEGGL should have the first three model developers above as co-authors (M. Jin, W. Manchester, I. Sokolov).
