View Full Version : Curious about METAR coding?

I have been "sorta" curious about the METAR coding used by the Observers for a long time. Some I've been able to figure out over time, but if I'm not paying strict attention, I lose the " language" and wind up scratching my head again.

I was going to ask here, but I asked Google instead, and Google helped me find this page:


Hope this helps others.

Close but the site you found actually decodes TAF's. They are similar to METAR but differ in many areas. So, don't study that page you found too much. A better resource I used when learning (apart from studying the FMH-1: http://www.ofcm.gov/fmh-1/fmh1.htm) is one of these two sites: http://atmo.tamu.edu/class/metar/quick-metar.html or http://weather.cod.edu/notes/metar.html#sky or if you want something to convert, there are plenty of sites that you can see the original and the decoded ones to see the differences. One is http://leonardo.met.tamu.edu/Weather_Interface/ and the other is http://heras-gilsanz.com/manuel/METAR-Decoder.html. While working at KSJC flight tower, I found learning TAF's took a bit longer to memorize compared to METAR's. But to each their own.

Thanks Ryan Knapp for the great resources.
