Ammonia emissionDefinition (http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.484.8060&rep=rep1&type=pdf) Ammonia (NH3) emission is normally reported as a mass flux, defined as the product of the difference in ammonia concentration between the source and the atmosphere and a mass transfer coefficient.
dM/ dt = KL ([NH3(aq)] - [NH3(air)]) where: KL- mass transfer coefficient for NH3 (m/s), and dM/dt is the mass of NH3 released in time t(g/s).
