Re: Conversion for GEOS

The program is using an existing CFG file. You need to delete it before running the updated executable. Otherwise, the program will use the old CFG file instead of creating a new one. Make sure the GRIDS(10) and GRIDS(11) are lat/lon coordinates of the 1,1 grid point. Ps. for the mer2arl program, th...

Re: Compiling mer2arl issue and segmentation error

You can use the precompiled mer2arl executable in ~/exec directory. Check if you have all the required libraries installed and linked. Instructions about this are in README_external_libraries.txt. If you compile the program in ~/data2arl/mer2arl directory yourself, the Makefile should be modified by...

Re: ARW2ARL issue with WRF V4

What problem do you have converting WRF v4 output to the HYSPLIT format?
There is no need to change the WRFDATA.CFG file unless the variables in your WRF files are different from those listed in the default CFG file.

Re: Error in using arw2ral

It looks like you have multiple WRF output files in the ARLDATA.BIN, but the data may be incorrect chronological order.

Re: arw2arl precision

There is a technical note for the arw2arl converter: https://www.ready.noaa.gov/data/web/mod ... rw2arl.pdf
You can use the example of WRFDATA.CFG to include DIFR and DIFW for the better precision of precip and vertical velocity.

Re: problem using 20120812_gdas0p5

It looks like there are bad values in the gdas0p5 files for those two days. You may add gdas1 (1 deg) data to the CONTROL that the model will switch using the 1 deg file during the hours when 0.5 deg data are not available. 12 08 11 22 1 78.93 11.95 50 -12 0 11000 2 /pub/archives/gdas1/ gdas1.aug12....

Re: error: concentration display file not created

Was the simulation done successfully? You can check the size of the cdump file and the MESSAGE file. They should be in your working directory.
Section 8.2 in the HYSPLIT tutorial has instruction for displaying the result: https://www.ready.noaa.gov/documents/Tu ... _disp.html

Re: Diameter (µm) Density (g/cc) and Shape

HYSPLIT uses the UTC time. More info about the CONTROL file can be found in the user guide (starting p24): https://www.arl.noaa.gov/documents/reports/hysplit_user_guide.pdf For the conc grid (output file from HYSPLIT runs), it is in lat/long coordinate and is independent of the input met data. You c...

Re: Single Site Profile

Did the error message come out of running sfc2arl? Can you share your single-site met file? I created one myself (shown below) with boundary height ranging ~400 to 1000m and ran sfc2arl successfully. 07 09 04 10 00 1006 0937 0020 0078 412.0 260 4.8 4 00175 07 09 04 11 00 1007 0937 0021 0079 552.0 27...

Re: Testing of Captex2 Simulation

This sounds to me that the CONTROL and SETUP.CFG were configured differently than the tutorial. Those files are available to download at the bottom of the tutorial page: https://ready.arl.noaa.gov/documents/Tutorial/html/conc_cexp.html Would you upload those two files? That will be helpful to know h...
