HYSPLIT Registration Instructions
HYSPLIT registration is ONLY required by non-NOAA employees to use the HYSPLIT dispersion model on the web with forecast meteorological data or to download the LINUX or registered version of HYSPLIT for the PC or Mac computers. Please do not register if you will only be using the HYSPLIT trajectoy model or the dispersion model with archived meteorological data.
To become a registered HYSPLIT user you must have a formal affiliation with one of the following institutions engaged in atmospheric sciences or in the provision of atmospheric operational products, and whose credentials we can verify either by a letter/email from your supervisor or by a reference to you on your employer's web site: government, commercial, eductional, or non-profit. If you do not have such an affliation, you may also register if you are sponsored by another already registered user of HYSPLIT, provided that they will be your contact point for questions about HYSPLIT and issues related to running the registered version of HYSPLIT (PC or web).
