Re: Altering the CONTROL file for Matrix Calculation

The CONTROL file is simply a text file so you can write your own program to write out the points and insert them into the CONTROl file.

Re: Grid Resolution

It is not generally true that increased output grid resolution will improve model results. Sometimes it will actually degrade model results. Generally speaking, higher concentration grid resolution may be beneficial for predicting concentrations at shorter transport distances and times or near the e...

Re: Gaussian/Top Hat model parameters

With the puffs you may also need to make your concentration grid finer. Some of your puffs may not be counted if they go between grid cell centers. See: https://www.ready.noaa.gov/hysplitusersguide/S622.htm A mixed-mode may be selected to take advantage of the more accurate representation of the 3D ...

Re: Altering the CONTROL file for Matrix Calculation

In the matrix run, a pre-processor program latlon is called which re-writes the CONTROL file to have more source points. 1 You can use that pre-processor program to write your CONTROL file with lots of points and then edit it to put the lat and lon with 3 decimal places. Then do a regular run with t...

Re: Gaussian/Top Hat model parameters

Is it safe to say that using the hybrid functionality of gaussian dispersions (for area emissions scenarios) depends heavily on the meteorology at a particular time? I'm trying to run several days in a batch run but I only get the 'maxpar' error (and mass differences) on certain days. Is this becau...

Re: HYSPLIT error

Yes. I need the whole MESSAGE file to see where it stopped running and if there are any warnings.
Also, could you please provide MESSAGE file for the hycs_std run.

Thanks.

Re: HYSPLIT error

I think the next steps are:

1 Send me your MESSAGE files.

2 try compiling with gfortran and see if that makes a difference.

Re: HYSPLIT error

If you are using hycm_std, I think your error message may be related to the stack size limit. People running WRF seem to get this error. I haven't seen it with HYSPLIT before, but I don't think we have as many people using the hycm_std version. Someone in the WRF forum suggested "ulimit -s unlimited...

Re: Fortran Runtime Error

I was able to run with your CONTROl and SETUP.CFG file. You have an error in the CONTROL file you sent though. The longitudes do not appear to be correct since latitude 48, longitude 11 is not with the US and the nams meteorological files you are using are not global, they are only CONUS. So, once I...

Re: HYSPLIT error

I am not able to reproduce your error, even running with numpar=100000. forrtl:error(69): process interrupted (SIGINIT) Are you using the multi-processor hycm_std? or hycs_std? It looks like the error is system dependent so it may take a bit to track down. Can you please attach a MESSAGE file. The M...
