<p dir="ltr">These are the summer OpenGGCM emissivity cubes used in the CMEM work by Wharton et al. </p><p dir="ltr">They have been produced by running 24 separate OpenGGCM MHD simulations using the runs on request service provided by the Community Coordinated Modeling Centre. I have then calculate the emissivity using standard assumptions where the alpha value is 10^-15. They have then been masked using a magnetic field criterion, where each point is traced to determine whether it is on an open or closed field line. Any point on a closed field line has its emissivity set to zero. </p>
