Editing an EMITIMES File

Start with the CONTROL and EMITIMES created in the previous example

Edit EMITIMES to create one emission cycle
(with 24 data records)

Edit CONTROL to match EMITIMES
(6 sources x 4 pollutants = 24 records)

Run HYSPLIT

and particle plot

The three emission cycle simulation showed 17157 particles at the end of 36 hours while the single emission cycle simulation showed only 6716 particles because in the name list file NUMPAR was set to 5000 particles per emission cycle.
