The middle atmosphere (MA; stratosphere and mesosphere, 12 to 90 km altitude) is a transition region between the troposphere under the direct influence of anthropogenic activity and the upper atmosphere (thermosphere and ionosphere) at the edge of the space and strongly impacted by the solar activity. The MA is then under the conjugated influence of climate changes, due to anthropogenic activities and natural variability.

The goal of this ISSI Team is to bring experts from different middle atmospheric observational communities together in order to evaluate and benefit from the complementarity and synergy between data recorded by ground‐based and by satellite‐based platforms. A better representation of the MA dynamics will be beneficial not only to the MA research community, but it will also pave the way for enhanced use of these data in the a broader atmospheric modelling context, in numerical weather prediction, and in climate modelling communities.
