HYSPLIT Forum: hysplitbbs.arl.noaa.gov

I noticed where Roland Draxler (on his private website) has posted new fortran code for a faster trajectory clustering algorithm based on k-means clustering. Are there any plans for NOAA-ARL to include this in the next update to HYSPLIT?

Of course it would be the simple thing! Vmixing runs fine now! Thanks so much for the help!!

Sonny,

Thanks for the assist! Unfortunately, I am getting the same message I got before.

I am using the 2019 tutorial on vmixing to estimate mixing height over an air quality monitor during an ozone season. I've set up the CONTROL and SETUP.CFG files in a folder outside of the working folder in C:\hysplit. That folder is C:\hysplit\vmix. When I try to execute the vmixing program I use ...

Thanks for your help!! It is much appreciated!

In reviewing the readme file for the new WRF 27km meteorological data, I ran across some fields that I'm not familiar with. I looked at readme files for other types of archived data and at READY Meteorological Field Descriptions (https://www.ready.noaa.gov/READYflddesc.php) and could not find ...

Mark,

Thanks very much for following up on this. It will be a big help!

I am wanting to use vmixing.exe to generate mixing heights and stability information for various locations for longish time periods. Based on posts elsewhere in "General questions on meteorological data needed for HYSPLIT" I have been able to generate this information for only a month at a time. I ...
