Considerable effort has been made in recent years to develop models that describe the time
evolution of the radiation environment in the inner heliosphere. These models have reached
considerable sophistication such that real-time and ~1-hour predictive modeling of the radiation
environment is being carried out. We show recent model results and comparisons between model
results and recent observations from the Cosmic Ray Telescope for the Effects of Radiation
(CRaTER) on the LRO mission. Model results and validation studies suggest a path for the
development of greater predictive capabilities that should greatly aid human exploration
missions.
