Validating Local Responses in OVATION Prime-2013 and OVATION-SM with DMSP SSUSI
Abstract
Particle precipitation is an observable phenomenon, which results from the coupling of the magnetosphere to the ionosphere-thermosphere as well as the influence of the ionosphere-thermosphere on the magnetosphere. Particle fluxes are often an input parameter for ionosphere-thermosphere models and atmospheric models, but also delineate the boundary conditions for magnetosphere models. Particle precipitation is also used to calculate ionospheric conductivity. For the above reasons, the accurate modeling of particle precipitation is of great value to the space weather community. Validation of particle precipitation models requires both global and local comparisons of data. This study compares the local and global auroral power, energy fluxes, and number fluxes of the OVATION Prime 2013 and OVATION-SM models with those retrieved from the DMSP SSUSI and DMSP SSJ/5 instruments over a variety of space weather conditions. Comparisons of peak fluxes, power, and spectral responses are used to determine how well the skill of the OVATION models predict particle precipitation, and determine the range of validity of each OVATION model.
