Simulation of the August 21, 2017 Solar Eclipse Using the Whole Atmosphere Community Climate Model – eXtended (WACCM-X)

The total solar eclipse of August 21, 2017 transited the entire continental United States.  This presented an opportunity for model simulation of eclipse effects on the lower atmosphere, upper atmosphere, and ionosphere.  The Community Earth System Model (CESM), v2.0 will include a functional version of the Whole Atmosphere Community Climate Model - eXtended (WACCM-X) that has a fully interactive ionosphere and thermosphere.  WACCM-X, with a model top up to ~600 kilometers, is an atmospheric component of CESM and is being developed at the National Center for Atmospheric Research in Boulder, Colorado.  Here we present results from simulations using this model during a total solar eclipse.  This not only gives insights into the effects of the eclipse through the entire atmosphere from the surface through the ionosphere/thermosphere, but also serves as a validation tool for the model.
