Hi everyone,

I am using the dispersion model for a gas. 522 emission sources were included in my EMITIMES file. I am wondering if there is any limit on the max number of emission sources and the emission duration time as well?

Here is the beginning of my EMITIMES file:

YYYY MM DD HH DURATION(hhhh) #RECORDS
YYYY MM DD HH MM DURATION(hhmm) LAT LON HGT(m) RATE(/h) AREA(m2) HEAT(w)
2008 12 01 00 50000 522
2008 12 01 00 00 5000000 42.36 -73.58 50 28200000000 1380000000 0.0
2008 12 01 00 00 5000000 42.25 -78.02 50 622000000 2678000000 0.0
2008 12 01 00 00 5000000 40.84 -73.89 50 14700000000 149000000 0.0
2008 12 01 00 00 5000000 42.16 -75.82 50 2620000000 1852000000 0.0

Thanks for help!

There is no limit to the number of sources in the EMITIMES file. Just make sure you put the same number in the CONTROL file.
