The MLS CH3CN Product
Basic Information
CH3CN is a long-lived pollutant whose atmospheric source is, primarily, biomass burning.

How it is part of MLS Science Objectives
One of the MLS objectives is to quantify aspects of how pollution affects chemistry of the upper troposphere and stratosphere, with consequent effects on climate and ozone layer stability. CH3CN is a long-lived pollutant whose atmospheric source is, primarily, biomass burning. The MLS CH3CN data will help quantify the extent to which biomass burning might affect upper troposphere and stratosphere chemistry.
How EOS MLS measures CH3CN
The standard methyl cyanide product is taken from the 190 GHz (Core+R2A) retrieval.
