HYSPLIT Forum: hysplitbbs.arl.noaa.gov

I would like to release different species (of different sizes), at different levels. I understood the the height of the release was set up as part of the location in the CONTROL FILE. So to make release at different levels, I should make multiple runs. Is there a way to define all the different release levels as the initialization of one run only?

Yes - you can utilize an additional input file called an emitimes file.
There is some information about how to construct it here:

Usually people set up a script to write it rather than relying on the GUI interface.
If you use python, there are some python classes to help with writing one.

It can be a bit tricky to get the format correct so feel free to write back with any questions/problems.

Thank you! It is exactly what I was looking for.
