Background information:

The Graduated Cylindrical Shell (GCS) modeling technique for CMEs was developed by Thernisien, Vourlidas and Howard at the U.S. Naval Research Laboratory, Washington D.C., USA. The following paper describe the GCS model in detail:

First results based on this CME study are published by Bosman and available at:

A short tutorial which introduces the usage of the modelling software is published online at: synomaps/scraytrace/dobo/examples.html

To run the modeling software the Interactive Data Language (IDL) in addition to SolarSoftware is required:

A quick introduction/short manual on installing and using the software environment for the CME modelling can be found here:

Database description:

The CME modeling results are stored in a MySQL database which is accessible through the "Database" section. Here one can find a list with all detected CMEs and the modeling results for a selected set of "Best-of" CMEs. For each event the following information is provided: CME date and time, position angle (PA), spacecraft positions, CME speed taken from the SOHO/LASCO CME catalog or derived from applying the CME Analysis Tool (CAT) modeling technique developed by Millward et al. in 2012 at NOAA - Space Weather Prediction Center, Boulder, CO, USA. The CAT Tool is published in:

Millward, G., Biesecker, D., Pizzo, V. and de Koning, C.A.: 2013, An operational software tool for the analysis of coronagraph images: Determining CME parameters for input into the WSA-ENLIL heliospheric model, Space Weather, 11, 57-68.

Additional flags have been added to indicate Halo CMEs, etc. The GCS modeling results are provided for 241 CMEs of the COR2 "Best-of list". Further explanations can be found in the "Legends" at the top of the Table and through clicking on each CME item. For a subset of the modeled CMEs the underlying low coronal and photospheric source regions (SR) have been identified and listed under "Source Region Results".
