Re: How to get meteorology output along the trajectory on LINUX

The tutorial has example linux scripts in many of the sections. Simply click on the icon of a penguin at the top. https://ready.arl.noaa.gov/documents/Tutorial/html/test_traj.html You can simply edit the TRAJ.CFG and SETUP.CFG with any text editor and then use them to start a run. The user guide has...

Re: Time varying source

You should only have two source locations in your control file. The number of source locations in the control file is important because array allocation occurs before the EMITIMES file is read. So the number of source locations in your control file multiplied by the number of particle sizes that you...

Re: Time varying source

Each Emission Cycle must have the same number of lines. So if you have 24 lines in your first emission cycle, you must also have 24 lines in your second emission cycle. If you don't need 24 lines in your second emission cycle, you can add "dummy" sources by setting the rate and duration to 0 for som...

Re: Time varying source

An EMITIMES file can handle almost any emission scenario. https://www.ready.noaa.gov/hysplitusersguide/S417.htm Constructing the more complicated ones can be confusing though. Here is a short example of what you want to do (If I understand your description correctly). YYYY MM DD HH DURATION(hhhh) #R...

Re: ERA5 dataset

I'm not sure I understand the trouble you are having with downloading the files. How are you trying to download them? Are you using the python code or other way? Can you describe this problem in more detail? The reason you are getting the error from era52arl is that you need to input at least 2 grib...

Re: Release height/top of domain ignored?

The height output by the PARDUMP file is not exact. In HYSPLIT, the vertical, z, position of the particle is converted to a terrain following coordinate. Zt = 1 - z/ (zmdl - mter) where zmdl is set either to 25000m or to the top of the model domain specified in the CONTROL file, whichever is greater...

Re: ERA5 dataset

Try using type='an' rather than '4v'

Please also see python code for downloading ERA5 data that can
be used in the converter at

Re: ERA5 dataset

The first thing to do would be to make sure that latitudeOfFirstGridPointInDegrees is contained in your grib file. Try using the command line utility grib_dump that comes with eccodes. https://confluence.ecmwf.int/display/ECC/grib_dump PATH/grib_dump -D DATA.GRIB will output all the key names in the...

Re: Error while clustering back trajectories

The program should also create a CMESSAGE file in your working directory.
Can you see what it says?
