Abstract

An optically thin layer of carbon monoxide in the Earth's mesosphere results in strong, sharp emission peaks at CO's rotational transition frequencies. The J = 2 → 1 and J = 4 → 3 transitions were observed by the Antarctic Sub-millimeter Telescope / Remote Observatory (AST/RO), located at the Amundsen-Scott South Pole station. Mesospheric wind speeds were calculated from the Doppler shifts in emission spectra, as determined by least-squares fitting.
