Re: Plotting multiple sources for the ensemble mean

If each of your member runs has 2 source locations, then the mean will show the two sources (stars). Was that what you ran? However, if each member has a different source location, then the mean will only show the source location (star) of the cdump.001 run.

Re: HRRR meteorology error

There was a problem with the file 20200902_18-23_hrrr, but we were able to fix it. Let us know if you have issues with that file or come across any other similar issue. Please see the bottom of the README.TXT file because there are some missings.

Re: Hello,

The clusters are determined from the endpoint latitude and longitudes, not the heights. The heights, but not pressures are carried through to the output. For example see the file C1_5.tdump (open in Notepad), which is what is used for the Cluster 1 of 5 plot you show. There is a latitude, longitude,...

Re: Incorporating Visibility?

Can you give us documentation on your smoke plume model? The current version of hysplit should be giving you concentration. Then you relate that to visibility?

Re: Test case for benchmarking MPI run

We do not have an MPI benchmarking case, though we should probably add one.   Some questions in general regarding run duration: Increase the meteorological subgrid size to lower the number of reads, for example to MGMIN=300 or more.  If MGMIN is larger than the grid, the whole grid is read.  The MES...

Re: PARDUMP zero lat/lon?

Do you expect particles to be in the vicinity of 0 degrees latitude, 0 degrees longitude? If not, please attach your CONTROL and SETUP files so we can try to reproduce it. Thanks.

Re: Automated multiple trajectories

Go to the Tutorial at https://www.ready.noaa.gov/documents/Tutorial/html/index.html Go to Section 6.1 Frequency Analysis, which is where Run Daily is run. Click on the linux (penguin) icon at the top of the page and open the file in Notepad. Run Daily in the GUI just is the looping through date/time...

It should be fixed now. Thanks for telling us about this.
