Extended Mission 07.29.20 AIM has been selected for five previous extended missions following the 2-year Explorer baseline mission. As noted in the 2017 Senior Review (SR) proposal, AIM has evolved to become a global mission. That proposal began capitalizing on this transition with three Prioritized Science Goals (PSGs). PSG-1 examined GW origins, how dynamical variability in the lower atmosphere couples to geospace weather and how extraterrestrial phenomena propagate into the lower atmosphere. PSG-2 studied the roles of solar and anthropogenic forcing on PMCs and the structure of the mesosphere. PSG-3 investigated the geographic and temporal distributions of mid-latitude PMCs and how they are influenced by waves and tides, but this was exploratory in nature due to the low signal-to-noise for PMCs at mid-latitudes. For PSG-1, significant progress was made developing new GW products to identify global GW “hotspots”. For PSG-2 we discovered that surprisingly, the solar c...
