GEM-CEDAR
Summary
The CEDAR-GEM Challenge was initiated during the Summer 2011 Joint CEDAR-GEM Workshop and is build upon GEM GGCM and CEDAR ETI Challenges. The project focuses on various scientific and operational aspects of magnetosphere and ionosphere models performance and addresses challenges of model-data comparisons and metrics studies (e.g., model output and observational time series preparation for comparison, measurement uncertainty, metrics selection). A list of selected events, lists of physical parameters and available measurements, model output file formats for each metrics study, and submission instructions can be found here.

- The tools are based on Kameleon converter and interpolator for 2D ionosphere electrodynamics files to swap ionosphere drivers at any position (geomagnetic latitude and MLT) or on any grid with any time resolution (https://ccmc.gsfc.nasa.gov/pub/GEM-CEDAR/out/high-latitude-drivers): there are CDF files with SWMF IE, SAM, and AMIE for several selected storm events.
