Water vapor content in the polar atmosphere measured by Lyman-alpha/OH fluorescence method
The water vapor of the polar stratosphere possibly plays an important role in various aeronomical processes; for example, OH radical formation through photodissociation of H2O, formation of water cluster ions, radiative energy transfer in the lower stratosphere, condensation onto particulate matter,...
