The AE9/AP9 climatology models integrate the latest observations and science into a tool satellite designers can use to develop radiation specifications for missions traversing the Earth’s radiation belts. The model covers trapped radiation and plasma from keV to GeV energies. It provides mean and transient environments, with confidence levels to assess margin. The model is under active development, with major updates occurring every one to two years to further address community requirements. The Version 1.5 update, due in 2017, will incorporate new data including energetic proton and electron data sets from NASA's Van Allen Probes mission. We will present an overview of the model as well as a look ahead at upcoming features and improvements.
