Buying, Operating, & Maintaining AWOS
Buying an FAA-Certified AWOS
Please be sure to select an Automated Weather Observing System (AWOS) that has been certified by the FAA. Refer to the latest List of Certified Non-Federal AWOS Systems and Vendors (PDF).
Please also ensure that you’ll be able to hire a maintenance technician who is eligible to receive FAA-issued Verification Authority for the type/make/model AWOS that you want to buy.
Putting Your AWOS "On the Map"
To help ensure that the aviation community knows about your AWOS, please verify that it's listed on the FAA's Surface Weather Observation Stations webpage. If you see a discrepancy, click on the page's "contact us" link.
Sharing Non-Federal AWOS Weather Data with the FAA and Aviation Community
AWOS play an important role in providing the aviation community with current meteorological data.
The FAA collects aviation-weather data from various sources. It then disseminates meteorological data products, such as METARs. Dissemination occurs via an FAA system known as "WMSCR" - the Weather Message Switching Center Replacement.
Owners of AWOS III (or better) can share their data with the FAA and aviation community. To do so, they must contract (for a fee) with an FAA-approved third party service provider. The service providers collect METARs from individual AWOS, and then pass them on to WMSCR.

Understanding the Different Types of AWOS Maintenance
Bushes, Crops, Trees, Weeds, Etc.
Overgrown vegetation poses a number of risks to AWOS. This 1-page brochure on the dangers of vegetation (PDF) can help you mitigate those risks.
