UAF EPPIM is the first principles theoretical model of the polar ionosphere, which covers region pole ward from 50 N of geomagnetic latitude, and altitudes from 80 to 900-1000 km. If available, the model can input real data or, conversely, it is capable of generating all necessary inputs using statistical modules (e.g., MSIS, electric field, precipitation intensity, etc.) incorporated into the model and driven by the standard set of geophysical indices (F10.7, Ap/Kp, IMF). UAF EPPIM is a computationally robust scaleable high-resolution model, capable of running on a range of platforms from desktop to a parallel supercomputer. Its real-time performance with useful resolution of 30x30x10 km or better can be achieved on a low-cost workstation. The model real-time continuous operation is arranged at the Arctic Region Supercomputing Center (ARSC) of the University of Alaska Fairbanks (UAF). It is based on automatic updates of the UAF EPPIM standard inputs (F10.7, Ap/Kp, and IMF), which are regularly fetched from the NOAA Space Environment Center (SEC) online depository. The solar wind IMF information from the upstream-located ACE satellite is available with advance of up to 2 hours, which facilitates forecasting mode of the ionospheric model. The model time is shifted forward to accommodate this time advance for the arriving solar wind. The forecast products in a number of formats are output in to the model WWW-site (http://www.arsc.edu/SpaceWeather) for immediate dissemination to the users and for past analysis and archiving. Statistical determination of the forecasting accuracy is performed by massive comparisons (>200,000 per year) with the NOAA SEC ionosonde data. The emulated critical frequency foF2 is automatically compared to the real-time data from about twenty sounding stations situated inside the model domain.
