Re: Trajectory > Display > Frequency > Create File of Trajectory Filenames Not Outputting New .bin File

The "Create file of trajectory filenames" creates a text file. The "Execute Display" creates the binary file. This is explained in section 6.1 of the (basic) Tutorial at https://www.ready.noaa.gov/HYSPLIT_Tutorials.php

Re: Error while using grib2arl

I am not familiar with the data at rda.ucar.edu. NCEP used to produce grib1 format data, but now produces grib2.

Re: All concentration output is Zero!

What is different in this run from the previous run that worked? Look at your CONTROL and SETUP.CFG files.

Re: Error because of pollutant wet deposition option

Was api2arl using the NCEP GFS 0p25 data successful? Does it have precipitation? Run chk_file on the file.

There are GFS 0p25 files that can be input to HYSPLIT at ftp://arlftp.arlhq.noaa.gov/archives/gfs0p25/ however they are on the GFS hybrid levels, not pressure levels.

Re: Problem with emission location

The CONTROL file and the plot label both have 63.333. It looks about right on the plot.

Re: Hourly trajectory with 3-hour resolution GDAS

This question relates to the accuracy of the meteorology data and hence accuracy of trajectory. When a trajectory is calculated from one grid point at the time of the meteorology, and you are calculating the trajectory until the next meteorological time period, do you know the actual wind at every t...

Re: dispersion model in water

HYSPLIT does not access oceanic data. I am not too familiar with NOAA's water models but a place to start may be the Global Real-Time Ocean Forecast System - https://polar.ncep.noaa.gov/global/

Re: Problem with emission location

How far off is it? The graphic wasn't attached. Have you tried plotting with Google Earth instead?
