This page will eventually hold more information about the publicly available solar wind forecasting code I have been writing called TEMPEST (The Efficient Modified-Parker-Equation-Solving Tool). For now, you can find it on GitHub at github.com/lnwoolsey/tempest
Current 3-day Solar Wind Speed Predictions: Shown here are the past three months of predictions using the WSA model (Wang & Sheeley, 1990; Arge & Pizzo, 2000) from the Space Weather Prediction Center. Note how often the wind speed is over- or under-estimated by more than one hundred kilometers per second. This gives an idea of how much the space weather community would benefit from a more accurate solar wind prediction code such as TEMPEST.
