HYSPLIT Forum: hysplitbbs.arl.noaa.gov

Dear sir/madam This is a two parter question a) Can I get a little bit more clarity about the duration of time for back ward trajectory? E.g. in the recordings the time for backward trajectory is 68 hours. Is it 68 hours backwards from the starting date time of release of tracer? 2) Does HYSPLIT giv...

I have a question regarding source geolocation.In the tutorial, a sampling data in form of DATEM format has been provided. How can I provide the same for my trajectory calculation? I have a GDAS file. Is it possible to obtain the data in a similar format?

Thank you very much. That helped a lot.

how to find out the Height of Planetary Boundary Layer in the gdas file? I have used the Text Profile option but I am unable to see the HPBL option in the text box. Is it denoted by any other terminology?

Sir/madam I have downloaded the archived metrological file gdas 0.5deg resolution. I want to run a back trajectory analysis at 13 degrees N 85 degrees E location. How do I achieve this? Should I go to convert to ARL---> Global Lat lon and then set the desired coordinates? I have tried the same but I...

While doing single particle animation, while generating a gif file of concplot, I am getting an error message as Invalid density and there is no gif plot being generated. What could be the reason for this?

Sir/madam I have downloaded the tutorial file through the link which you have given. Many thanks for that. Now under multiple trajectories in space section, there is this line "One element to remember from this section is that when the setup menu was configured for three locations the resulting cont...

Also, there seems to be no captex folder on my PC. there is only one file named captex2.bin file with which I was able to use to follow all the steps mentioned in the tuto...

Sir/mam
there is no captex2_narr.bin on my PC. What should I do? Are there any other additional sources for downloading captex2_narr.bin file. This is with respect to finding absolute trajectory error.
