SA21B:
Solar Eclipse Effects on the Upper Atmosphere II Posters

Submit an Abstract to this Session



Session ID#: 26657

Session Description:
For the first time in 26 years, a total solar eclipse will occur in the North American on 21 August 2017. During the eclipse-induced sudden interruption in solar illumination, the upper atmosphere will undergo significant changes beyond what a normal sunset and sunrise process would generate. Although eclipse effects have been studied for many decades, recent major advances in modern observational techniques can provide timely new information on eclipse upper atmospheric system response. Global numerical models have become more capable of capturing important coupling processes on various scales. This session will review existing theories and knowledge of eclipse upper atmospheric effects, examine these against modern eclipse observations, in particular during 21 August 2017, and identify unresolved and challenging problems for future research. We welcome contributions addressing scientific questions of the ionospheric, thermospheric and mesospheric variations during a solar eclipse using ground-based and in situ measurements as well as numerical models.
