A new probabilistic model for protons has been created using episode integrated fluences. This model will allow the user to choose a mission start date, mission duration, and confidence level to construct a mission-specific, bounding case spectrum for proton fluences at a distance of 1 AU from the sun. A new database of episode integrated fluences will be created for this model. The database will contain 29 channels that span the energy range 0.88-485 MeV. This database will cover the period from November 1, 1973 to December 31, 2013, making it the largest database on solar activity.
