OVATION Prime is a seasonal model of the diffuse, monoenergetic, proton, and wave aurora.

The OVATION Prime model is written in IDL and was developed at the Johns Hopkins Applied Physics Laboratory (JHU-APL) by Patrick Newell and co-workers. This current version includes updates to the retrospective and real time components, several efficiency enhancements and a user configuration as implemented by Rob Redmon and Janet Machol of NOAA. Documentation in the downloadable zip file includes a model description and instructions for running the software. This is a community model. Users are invited to provide and suggest improvements and augmentations.

A web interface for running the model for historical periods is available here:
