AB: The MLS instrument on Aura has made the first daily global measurements of the mixing ratio Hydrogen Cyanide. The signal from this molecule is not large but permits the retrieval of a daily zonal mean between 10 and 0.1mb and a weekly zonal mean over a somewhat greater vertical range. We describe the nature of the measurements and the technique employed in the retrieval process. The first three months of data are presented and compared with previous measurements of HCN.
