Hydrogen Cyanide (HCN) is a colorless, volatile, and extremely poisonous chemical compound whose vapors have a bitter almond odor.
HCN main source in the troposphere is the biomass burning. It is a tropospheric source gas that enters in the stratosphere and is slowly destroyed there. HCN is not only an indicator of biomass burning events, it also acts as a tracer to observe the dynamics of the middle atmosphere. Its primary loss mechanism is reaction with the OH radical. The HCN data from Microwave Limb Sounding (Aura/MLS) are based on observations of emission from spectral lines around 117 GHz.
