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...

Re: Custon Made NetCDF format

What variables do you want to include in the met data for HYSPLIT? What are they for? This note for the converter of WRF met data may be helpful for you. The table in the doc lists what variables from WRF match to HYSPLIT's required variables. https://www.ready.noaa.gov/data/web/models/hysplit4/deco...

Re: Error in converting GRIB2 data using api2arl

api2arl_v4 is an example to create a converter for GRID2 data. Some customization are always needed for different datasets. https://www.ready.noaa.gov/documents/Tutorial/html/meteo_cnvrt.html The cfg file lists the variables from the met data (atmgrb and sfcgrb) matching to those in HYSPLIT format (...

Re: *.ASC files (LANDUSE.ASC, ROUGLEN.ASC, TERRAIN.ASC) to use with *.gfs0p25 data

The GFS quarter-degree archive has terrain and roughness. So, HYSPLIT uses them when they are available in the met data instead of using those *.ASC files.
For calculating trajectories, the model does not require landuse and roughness length. They are for computing deposition.

Re: I need help about MCIP2ARL

This error message is about the IOAPI library. It failed because it could not find the PARMS3.EXT file in the IOAPI path you provided. Check if your IOAPI was installed properly.
