Re: add_grid

I tried 10 on your dataset and it similarly failed. In looking at the code at a first glance it seems like a higher divisor number should work, but I do not have the time right now to spend on this. If you revise the code to handle what you are trying to do, we can put it in the repository. Why are ...

Re: add_grid

It should have worked. Try running chk_file on addgrid.bin to see if the (1,1) values are non-zero given in the ASCII header are non-zero. If they are zero, have you successfully run HYSPLIT with your 1-degree file? Or run chk_file on your 1-degree file to check it. Clearly your 1-degree file must b...

Re: add_data routine

It's a problem of the meteorology data (gdas1). For example a lambert conformal grid would work.

Re: add_data routine

Are you using a lat-lon grid? The program add_data is designed for a conformal grid, not a lat-lon grid.

Re: Question about 'Number of particle and puff'

You are getting the "... exceeding..." message because the number of particles in the run reaches the maximum you specified (MAXPAR). For a description of what is in the MESSAGE file, see https://ready.arl.noaa.gov/hysplitusersguide/S443.htm You can increase the MAXPAR so you won't get the "exceedin...

Re: 'cdump' is empty

Actually looking back at the CONTROL file, I can see the issue. Your run has duration of 24-hours and is outputting 24-h averages. The run starts at 12 01 01 01 00 (00 is assumed because it's not otherwise specified.) The end of the 24-h sample is 1 minute after the end of the 24-h duration run (12 ...

Re: add_data routine

The date/time of the observation (Dec 24, 16 UTC) is before the start of the meteo file (Dec 22, 00 UTC).

Re: Cluster analysis PC/Python

This file exists and is the endpoints file?

C:/Users/User/Desktop/year4/thesisgithysplit/trajectories/clippedtraj/londonjan

If so, do a quick test and remove this line from INFILE, as the message states, and try it again.

Re: Pointer Select

Now I realize I was using an older version - April 2018 Release (SVN 951) - that does have Pointer Select. The more current version September 2019 Release (Version 4.2.0) - does not have it. It is an application that is no longer supported. We also need to update the online User's Guide you referenc...

Re: Cluster analysis PC/Python

If you used the hysplit program 'trajplot' to plot your python trajectories, the cluster program will work. The cluster file INFILE is a listing of all the trajectory endpoints filenames. It is in your working directory (generally c:\hysplit4\cluster\working or c:\hysplit4\working). If there is noth...
