Advanced Climatology Innovations for Space Radiation Environments

The Space Ionizing Radiation Environment and Effects Advanced Climatology (SIRE2-AC) tool will enhance the capabilities of space climatology, system design, and system performance evaluation. The SIRE2 toolkit will be modified to interface with the new iPATH tool, using the current conditions around the Sun to propagate the radiation environment to the Earth over the next few days. The radiation environment can then be propagated into the Earthrsquo;s geomagnetic field and an electronic part using the models available in SIRE2.The SIRE2-AC proposal is submitted to the Space Weather Research-to-Operations/Operations-to-Research (R2O/O2R) Technology Development subtopic and will provide an innovative tool to the space weather forecasting. The new capability for SIRE2 will provide enhanced forecasts of the energetic particle conditions encounter by spacecraft within Earthrsquo;s magnetosphere. SIRE2 can calculate the environment inside the Earthrsquo;s magnetosphere using the built-in geomagnetic cutoff models. Arbitrary trajectories can be read into SIRE2, allowing for environment calculations anywhere in the Earthrsquo;s magnetosphere, including Lunar space environments.The proposed Phase I effort will result in a demonstration of the SIRE2 toolkit that is able to use iPATH databases of the solar radiation component. This Phase I effort will also develop a synthesized SPE environment from the iPATH model for a selected significant SPE event. One such candidate events would be the August 1972 event.
