| Description | This dataset contains modeled auroral intensity distributions and comprehensive validation materials for comparing OVATION-AACGM and OVATION-Dipole (original OVATION Prime 2010) models. The OVATION-AACGM model enhances the physical interpretability of mid-latitude aurora visibility by integrating the AACGM v2 coordinate system, which better represents the actual geomagnetic field topology in mid-latitude East Asia. Data File Descriptions AACGM/ - Directory containing OVATION-AACGM model outputs in .sav format with geographic coordinates and energy flux for Northern Hemisphere.
