The Upper Atmospheric Physics branch of NRL's Space Science
Division is an internationally recognized center for the study of radiative,
chemical and dynamical processes in the Earth's middle and upper atmosphere.
NRL's Middle Atmosphere High Resolution Spectrograph Investigation flew
on the space shuttle twice to measure hydroxyl (OH) in the middle atmosphere.
The second mission in August, 1997 yielded unprecedented insight on the
distribution of water vapor (H2O) and PMCs in the Arctic summer mesosphere
that has led to new ideas on PMCs and their formation environment. NRL
brings this expertise in data analysis and modeling to AIM.
