Inverse dispersion modeling for ammonia emissions

1. QBLS = (CL-Cb)/(CL/Q)sim
Where
Q = emission rate of NH3
CL = average NH3 concentration
Cb = Background gas concentration
Backward-Lagrangian Stochastic (BLS)
 Simulates transport of NH3 from emitting source to
measurement location.
 Predict the ratio of average NH3 concentration (CL) to the
emission rate (Q).

2.  Wind Speed
 Wind direction
 Surface roughness length
 Atmospheric stability (Obukhor length, Friction velocity)
 Measured NH3 concentration
 Background NH3 Concentration
Why WindTrax?
 Experimental simplicity
 Absence of limitations on size and shape of emitting
source
 Flexibility in type and location of samplers
