Various emission rate
Hi everyone. I have a question based on the emission rate. In the dispersion modeling, can I setup different emission rates for different souces in one run. For example, Source A emission rate is 5 mass/hr, and Source B is 9 mass/hr?

Yes
The simple way is to just enter emission rate for different sources in the CONTROL file as specified below.

For more complicated emission scenarios, use an EMITIMES file.

(1)- Enter starting location (lat, lon, meters, Opt-4, Opt-5)
Default: 40.0 -90.0 50.0
Position in degrees and decimal (West and South are negative). Height is entered as meters above ground level unless the mean-sea-level flag has been set.
The optional 4th (emission rate - units per hour) and 5th (emission area - square meters) columns on this input line can be used to supersede the value of the emission rate (line 12-2) when multiple sources are defined, otherwise all sources have the same rate as specified on line 12-2. The 5th column defines the virtual size of the source: point sources default to "0".
For more complicated emission scenarios, use an EMITIMES file.
