Each Airport Weather Advisor™ system has a set of common components for data collection and processing and the configuration defines what sensing and reporting capabilities it has. Most U.S. airports opt for one of the AWOS III (AWOS 3) configurations or greater because the addition of the Ceilometer, providing an optional system connection to the National Airspace Data Interchange Network (NADIN).

AWOS LEVEL CAPABILITIES INCLUDE:

AWOS A: Altimeter settings
AWOS A/V: Altimeter setting and visibility
AWOS I: Wind speed and direction, temperature, dew point, altimeter setting, and density altitude
AWOS II: Wind speed and direction, temperature, dew point, altimeter setting, density altitude, and visibility
AWOS III / AWOS-3: Wind speed and direction, temperature, dew point, altimeter setting, density altitude, visibility, precipitation accumulation, cloud height, and sky condition
AWOS IIIP / AWOS-3P: Wind speed and direction, temperature, dew point, altimeter setting, density altitude, visibility, precipitation accumulation, cloud height, sky condition, and present weather
AWOS IIIPT / AWOS-3PT: Wind speed and direction, temperature, dew point, altimeter setting, density altitude, visibility, precipitation accumulation, cloud height, sky condition, present weather, and thunderstorm/lightning
AWOS IV Z / AWOS-4Z: Wind speed and direction, temperature, dew point, altimeter setting, density altitude, visibility, precipitation accumulation, cloud height, sky condition, present weather, thunderstorm/lightning, and freezing rain

There is no limit to the number of airfield stations and sensor configurations Mesotech AWOS can support, allowing you to adjust or increase your system as the situation dictates. This includes Runway Visual Range (RVR) using forward scatter visibility sensors.
