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.
What are the limitations of AWOS ASOS?
The upper limit of cloud height and visibility reported by ASOS/AWOS is 12,000 feet and 10 miles. The most common reason ASOS/AWOS cannot be received by telephone is due to maintenance or repair.
Are METAR clouds AGL or MSL?
Remember, METAR and TAF report the height of clouds AGL, not MSL.
How does AWOS determine cloud height?
Ceiling – Cloud height is determined by a ceilometer utilizing a laser transmitter to bounce signals off of the clouds.
How much does AWOS 3 cost?
AWOS prices range as much as their offerings, from $20,000 to $100,000 depending on the level of reporting. For approximately 75 percent of airports, an AWOS III is the most appropriate choice. It provides the minimum weather reporting requirements for most commercial operators.
What is ASOS/AWOS data?

How long can the AWOS 3000 archive data?
All algorithms used in processing your weather data are FAA and ICAO approved to ensure accurate information is sent to your airport users. The AWOS 3000 can archive up to one year of data, taken at 5 minute intervals. An AWOS printer is also available to help with report generation, error message reporting, and printing of archived data.
Where are Asos data archived?
ASOS data are archived in the Global Surface Hourly database. The Automated Surface Observing Systems (ASOS) program is a joint effort of the National Weather Service (NWS), the Federal Aviation Administration (FAA), and the Department of Defense (DOD). There are currently more than 900 ASOS sites in the United States.
Who makes AWOS systems?
All Weather Inc. is the world leader in the manufacture of AWOS systems. Since the award of the contract to supply the United States Federal Aviation Administration with 200 AWOS systems, and the National Weather Service contract to supply 1000 ASOS systems, All Weather Inc. has installed more systems than any other manufacturer.
