Airport identification codes

I'm an aviation newbie, so I don't know much about airport identifiers. What is the difference between the identifier "GHG", which is the identifier that the National Weather Service uses, and "3B2" which appears in this article? -Running On Brains 17:28, 28 February 2008 (UTC)[reply]
