The University of Michigan is involved in two projects:The NextGen Space Weather Modeling Framework project, funded by NSF, aims to accurately predict solar storms and coronal mass ejections a full day in advance. And Aether, funded by NASA, aims to improve models of Earths upper atmosphere. Other than a pandemic, a space weather-caused disruption is the only natural threat that would have nationwide impacts, said Gabor Toth, U-M research professor of climate and space sciences and engineering and principal investigator on the space weather modeling framework project.
