Model Description

The OVATION Prime model was developed using energetic particle measurements from the polarorbiting Defense Meteorological Satellite Program (DMSP) satellites and considers four types of aurorae: two types of discrete electron aurorae (1A: monoenergetic and 1B: broadband) and two types of diffuse aurorae (2A: electron and 2B: ion) [Newell et al., 2010]. The OVATION Prime model is written in IDL and was developed at Johns Hopkins Applied Physics Laboratory (JHU-APL) by Patrick Newell and co-workers. The model may be freely downloaded from SourceForge.

Ovation Prime provides statistical distribution of auroral precipitation in the ionosphere obtained from 11 years of DMSP electrostatic analyzer data. Observations have been binned by magnetic local time and latitude and by solar wind parameters (Vx, By, Bz, N).

CCMC services available: Model runs in real time using ACE real time solar wind data. Images feed iSWA cygnets.

Title in cygnet images type of precipitation included

all,e: 1A, 2B, 2A

all,e+i: all four (1A, 1B, 2A, 2B)

Eight cygnets exist for each of the above combinations of precipitation patterns (see example layout images):
