What does the remark AO2 indicate?
AO2: this is a weather station with a precipitation sensor. However, skipping to the end… $: the station has put in a call for maintenance.
What does A02 mean on Metar?
precipitation sensor
A02 means that the site is automated and HAS a precipitation sensor. If it were AO1, there would be no precip sensor. This does not mean the site is un-manned. If there is an AUTO after the ID in the metar ob, then there is no observer.
What is the difference between an AWOS and ASOS?
Whereas AWOS data typically includes ceiling and sky conditions, visibility, temperature, dew point, altimeter setting and wind speed, gusts and direction, ASOS can additionally provide the type and intensity of precipitation (rain, snow, freezing rain), and obstructions to visibility such as fog and haze.
What does AWOS measure?
The AWOS I system measures and reports wind data, e.g., speed, direction, and gusts; temperature; dew point; altimeter; and density altitude. c. AWOS II. The AWOS II system measures and reports all the parameters of AWOS I system plus visibility.
How do I read a METAR remark?
The first two digits are the date, the 16th of the month, and the last four digits are the time of the METAR, which is always given in coordinated universal time (UTC), otherwise known as Zulu time. A “Z” is appended to the end of the time to denote that the time is given in Zulu time (UTC) as opposed to local time.

What information does AWOS-3 provide that AWOS 1 does not?
AWOS-1 usually reports altimeter setting, wind data, temperature, dew point, and density altitude. AWOS-2 provides AWOS-1 plus visibility. AWOS-3 provides AWOS-2 plus cloud/ceiling data. ASOS provides AWOS-3 plus precipitation.
What does AO1 in the remarks of an ASOS / AWOS?
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. 1 in Chapter 12. This particular notation is: 12.7.1 c. Type of Automated Station (AO1 or AO2).
What’s the difference between AWOS and ASOS stations?
Almost all AWOS stations are operated and controlled by the FAA. Some local state agencies will take care of them, but the DOD and NWS have no role in their operation. These stations are automated and will report the weather every minute. This is probably the main difference between AWOS and the ASOS systems.
What is the meaning of remarks in Asos?
Remarks: Remarks or RMK may be encoded or in plain language and contains any additional data. Multiple remarks could be reported during one observation. Answer:The remark represents as the following AO2 = automated station that can distinguish between rain, snow, etc., SLP034 = seal level pressure at 1003.4 mb.
What does AO2 stand for in METAR SPECI?
12.7.1 c. Type of Automated Station (AO1 or AO2). AO1 or AO2 shall be coded in all METAR/SPECI from automated stations. Automated stations without a precipitation discriminator shall be identified as AO1 ; automated station with a precipitation discriminator shall be identified as AO2 .
