definition: The middle atmosphere program is developing theoretical tools with which to analyze and interpret data obtained by NRL experiments (such as MAS, MAHRSI, WVMS, and POAM II). MAHRSI in particular provides the first global measurements of the hydroxyl radical (OH) in the stratosphere and mesosphere. This radical may be the key to understanding the current discrepancy between model predictions and measurements of stratospheric and mesospheric ozone.
