HYSPLIT Forum: hysplitbbs.arl.noaa.gov

Hi I was trying to run Hyspit using output from a GCM. I used MeteoInfoLab to convert model data into arl format. I found few issues with the simulated trajectory 1) Trajectory doesn't show proper vertical motion when I used GCM vertical velocity (vertical velocity option =0). When I used divergent ...

Dear Yaqiang,
Thank you for the help.
It is a great tool!

Hi Barbara,
Thanks!
Now it is clear

Dear Yaqiang, Thank you! Great! It worked! Please see my script below. I have defined the lat/lon/time according to the description given at http://ready.arl.noaa.gov/gdas1.php. Is there any way to get the lat/lon/time values directly from the input file? infn = '/home/midhun/Downloads/gdas1.jun13.w...

Thank you. I found difficulty in unpacking the data using the given FORTRAN code. So I plan to download the original GDAS data from NCEP server. As I understand, precipitation rate (PRATEsfc) is not a variable in the GDAS analysis, so HYSPLIT taken it from the forecast fields (https://www.ready.noaa...

Ok. Is there any way to read .gbl file in matlab or in any other software?

Dear rolph, Thank you for your reply. I am able to simulate the rainratel along the trajectory. But this rainrate data is from model forecast (NCEP or GDAS). Hence I want to validate NCEP/GDAS rainrate with trmm or GPCP data. But the data input we use as hysplit input is in .gbl format. I want to kn...

Hi, I am interested in rain rate along the hysplit trajectory. I want to validate the rainfall data from NCEP/GDAS using trmm or gpcp. But i am unable to process the rainfall data in the hysplit input. Is there anyway to convert hysplit input data (.gbl file) to normal grib or netcdf data? Regards, ...
