What is AO2 in METAR?
The AO2 notation means the station is automated and has a precipitation discriminator. AO1 means automated but no precipitation discriminator. The precipitation discriminator will be able to sense the difference between rain and snow. The METAR format is documented in the Federal Meterological Handbook No.
How often are Metars issued?
TAFs are valid for a 30 hour time period and are issued 4 times a day at 6 hour intervals. The forecast includes forecasted wind speed, wind direction, visibility, ceiling, type of precipitation (i.e. snow, rain, etc.) and/or weather phenomenon.
