Water Vapor Millimeter-Wave Spectrometer (WVMS)

The Water Vapor Millimeter-wave Spectrometer project measures water vapor in the middle atmosphere (between about 30 and 80 km). Water vapor is the primary source of the OH radical and other hydrogen compounds, and is therefore important in controlling ozone chemistry. Because the chemical timescales for water vapor are long relative to timescales for transport in the middle atmosphere, it is also an excellent tracer of atmospheric motion. Water vapor profiles are obtained by measuring the emission of the 22 GHz transition of water vapor.
