 Abstract: CH3CN in the stratosphere has been measured by the Microwave Limb Sounder (MLS) on the Upper Atmosphere Research Satellite (UARS),
providing the first global CH3CN dataset. The MLS observations are in
broad agreement with past high and midlatitude observations of CH3CN,
although concentrations are a little larger than previously observed. In
the tropics, where CH3CN has not up to now been measured, a persistent
'peak' in the profiles is seen around 22hPa, which may be evidence of a
tropical stratospheric CH3CN source. Comparisons are made with the NCAR
SOCRATES model, including runs having an artificial tropical
stratospheric CH3CN source.
