Solar-Terrestrial Coupling through High Energy Particle Precipitation in the Atmosphere: a Norwegian contribution (HEPPA-Norway)

In order to improve our understanding of the effect of energetic particle precipitation upon the chemistry and dynamics of the coupled mesosphere-stratosphere system, and ultimately upon surface climate, the project will rely on combined modeling and obse rvational studies. Using particle precipitation measures from polar-orbiting or geostationary satellites as well as ground-based observations, we will investigate how the middle atmospheric chemistry and temperature are influenced by different types of energetic particle precipitation events, and improve the spatial and temporal characterisation of energetic particle precipitation events. Using modeling studies of energetic particle precipitation with a chemistry-climate model (WACCM) including improv ed parametrisations of ionic chemistry and of energetic electron precipitation, we will evaluate the chemical-dynamical couplings in the upper and middle atmosphere, and their potential surface and climate impact at high latitudes will also be examined. T he model results will be benchmarked against satellite observations.
