How to choose which meteorological data to use
Posted: February 29th, 2020, 3:28 am
Hello, I want to simulate the diffusion concentration of pollutants through hysplit. I chose rp201805.gbl. But I don't know if my choice is right. In other words, I don't know which meteorological data to use when simulating. Does anyone know how to select various meteorological data according to the needs? Or can each meteorological data be used, but the final effect may be different? Thank you first!

Please see the basic HYSPLIT tutorial at https://www.ready.noaa.gov/HYSPLIT_Tutorials.php
, particularly sections and 4.6 and 13.4.

You want to use the meteorology file (gridded, at finite time steps) that best represents the real meteorology. If you don't know which one that is, then run with all of them, and the differences indicate the uncertainty in the results.
