3.4 Meteorological Data Servers

Meteorological data to run the exercises in this tutorial are provided in the various example directories as indicated with each exercise. If you have access to the internet, then current or archived meteorological data in a HYSPLIT compatible format, may be downloaded from several different sources:

• ARL server forecast data


• NCEP server forecast data


• ARL server archive data

The above direct links may not be needed if the data can be downloaded using the GUI through the FTP menu tab. At some organizations, IT security practices may restrict FTP access only to approved FTP clients.

The ARL data can also be accessed indirectly through the READY system which provides links to the meteorological data as well as on-line HYSPLIT simulations. A description of the system can be found in the Journal of Environmental Software.
