The EMITIMES file you attached is the same one from the tutorial. The dates don't match up with your CONTROL file.

I am not aware of anyone working on an ACCESS-G to ARL convertor. If you develop one, we would be happy to include it in future HYSPLIT releases for other users to use.

Correct, HYSPLIT forces CMASS=1 when run with ICHEM=8. However, running with ICHEM=8, particles are still divided by the air density to output a mixing ratio output field.

Your CONTROL file is setup to write average concentrations every 0 hours to the cdump file, which can't be done. Change your CONTROL file to the following to write out average concentrations every 13 hours: 25 03 24 22 1 40.0000 -90.0000 150.0 -13 0 10000.0 1 /storage/group/zrb5027/default/Permian/j...

Are you running HYSPLIT with Linux or Windows executables? Updated source code and executables for Linux are now available on Ready. This update is Version 5.3.4.

Thank you! I was able to reproduce your bug, found when and where this entered into the code, and created a bug fix for this issue. This bug occurs when running a dispersion simulation with IDSP=2 for HYSPLIT versions 5.3.0, 5.3.1, 5.3.2, and 5.3.3. We are currently putting together new HYSPLIT dist...

Hi, I was able to successfully use HYSPLIT Version 5.3.0 to run a backward trajectory simulation and a backward dispersion simulation that passed through the dateline with a 1 degree GDAS file that is archived at NOAA ARL (https://www.ready.noaa.gov/data/archives/gdas1/). For dispersion simulations,...

1) For area sources, you want to use an EMITIMES file. See directions on how to setup an EMITIMES file in the user guide: https://www.ready.noaa.gov/hysplitusersguide/S417.htm Creating and using an EMITIMES file is also discussed in the online HYSPLIT Basic Tutorial: https://www.ready.noaa.gov/HYSPL...

Thanks for letting us know about these files. We updated these files and they are now available on our archive.

Note that there are two versions of the WRF 27 km ARL meteorology files (https://www.ready.noaa.gov/data/archives/wrf27km/README.TXT). One set of files contain instantaneous wind velocities and the other mass coupled time average wind velocities. The set of files with mass coupled time averaged wind...
