Unable to reproduce interpolation onto trajectory

I am working with CESM/CAM output data on hybrid levels, converted to ARL format with MeteoInfo (and hopefully soon cesm2arl) and run through the trajectory model. Ultimately I would like to take the trajectory location output (time/lat/lon/height or pressure) and use it to reference other variables...

Re: Strange output when hitting the ground

Thanks for the suggestions, I think I figured it out. I'm working with CESM/CAM data, and for a while I provided the 10-m zonal wind U10 but not the meridional wind V10. I have since discovered that the 'U10' variable provided in CAM4 is actually the total 10-m wind speed, not the zonal velocity, an...

Re: Error 23 when spanning 31 Dec 0039 to 01 Jan 0040

cesm2arl relies on a Makefile.inc that wasn't included in the tarball and doesn't seem to come with the version of HYSPLIT that is currently available on the website. Do you have a sample Makefile.inc that I could take and modify? I'm not familiar enough with compiling Fortran to figure out which va...

Re: Error 23 when spanning 31 Dec 0039 to 01 Jan 0040

Thanks for the suggestions! Manual adjustment of the year sounded like it would work, but I wanted to make sure there weren't any deeper problems I was missing. And great to hear the next update will include a converter for CESM files, definitely looking forward to using that.

Re: Error 23 when spanning 31 Dec 0039 to 01 Jan 0040

I re-ran the conversion and didn't get any errors from MeteoInfo. I made two more files per your suggestion, one for 31 Dec 00:00:00 through 21:00:00 and one for 01 Jan 00:00:00 through 21:00:00 (output every 3 hours), and chk_file worked fine for each of them individually. I made another file with ...

Error 23 when spanning 31 Dec 0039 to 01 Jan 0040

I run HYSPLIT using output from the CAM component of CESM, converted into ARL-friendly format with MeteoInfo. 99% of my data files, which have output every 3 hours for up to ten days, can be read by HYSPLIT with no problem, but if I try to run the trajectory model or the Check File program on a file...

Re: Error: invalid command name ".f.f.text"

Still erroring. I reset the GUI, re-loaded captex_control.txt and captex_setup.txt, then went into Advanced -> Configuration Setup -> Concentration -> Menu 4 and set Particles released per cycle to 2500. Saved, then went to Concentration -> Special Runs -> Test Inputs. I hit "Analyze", then error ap...

Error: invalid command name ".f.f.text"

While doing Tutorial 8.5 Test and Optimize Input Files, I started to get a pop-up with the message Error: invalid command name ".f.f.text". I've attached the .log file, as well as the captex_control.txt and captex_setup.txt that I loaded at the beginning of the tutorial. I followed the instructions ...

How is height converted to pressure when using hybrid sigma-pressure levels?

My input data is on hybrid sigma-pressure levels, similar to ECMWF (vertical coordinate system flag 4). How is the final column of the trajectory endpoints file, 'PRESSURE', calculated? I would like to be able to plot my source data in either height or pressure coordinates, but I want to make sure t...
