PDF (2018)The Probability Distribution Function (PDF) modelModel DescriptionThe Probability Distribution Function (PDF) model is a project of the Department of Climate and Space Sciences and Engineering from the College of Engineering at the University of Michigan. The Probability Distribution Function(PDF) model (Bussy‐Virat & Ridley, 20146) forecasts the wind speed at L1 up to 5 days in advance using probability distributions, which have been constructed by analyzing solar wind observations between 1995 and 2011. These PDFs specify the likelihood that a particular wind speed will occur, given the current speed and the current slope of the wind speed curve. The model also takes account of rotational periodicities at quiet times and was updated (Bussy‐Virat & Ridley, 2016) to improve its ability to identify stream interaction regions (SIRs).
