Whitepaper #166 in the Decadal Survey for Solar and Space Physics (Heliophysics) 2024-2033. Main topics: basic research. Additional topics: planetary ionospheres / upper atmospheres; space-based missions/projects; system science.
The global extent of atmospheric gravity waves is one of the great unknowns in upper atmospheric dynamics. New space-based techniques have been developed that have the potential of supplying much-needed data on their global distribution. The discussion in this paper is meant to alert the community of these techniques with the hope that one or more could be supported in future space-based missions.
