Continuous Ambient Air Quality Monitoring Stations

OSI's monitoring stations can measure a wide range of parameters including visibility, present weather (rain, snow, drizzle, freezing precipitation), precipitation type and rate, wind speed and direction, temperature, relative humidity, and barometric pressure. The AWOS-AV additionally provides dual-pressure altimeter settings and dual-visibility readings specifically for aviation safety requirements.

Yes. The AWOS-AV system is fully FAA-certified and complies with FAR 91.171 and FAR 91.175 standards, as well as ICAO requirements. It is designed specifically for airports, private helipads, and aviation facilities requiring official, certified weather observation. The MAWOS and OWI-432 WIVIS are non-FAA-certified options compliant with NWS and WMO standards.

OSI's monitoring stations are engineered for virtually zero maintenance. The no-moving-parts optical sensor design requires no scheduled cleaning and is insensitive to dirt buildup on optics. Built-in continuous self-test and self-diagnostic systems monitor performance automatically. The system's MTBF exceeds 80,000 hours, making it ideal for remote, unattended, and critical-infrastructure deployments.

Yes. The MAWOS and OWI-432 WIVIS stations support solar panel, battery, and standard AC power configurations, enabling deployment in remote and off-grid environments. They operate across an extreme temperature range of -50°C to 60°C and have been deployed in environments ranging from Antarctica to tropical rainforests, making them suitable for virtually any geographic location.

OSI's stations support multiple communication interfaces including RS-232 (standard), RS-485, Ethernet, Limited Distance Modems (LDM), and optional cellular modems. Data can be transmitted in ASCII data strings or MODBUS RTU formats. The AWOS-AV system provides real-time data transmission directly to ATC facilities, generating automated METAR weather reports for flight operations.

OSI's continuous monitoring stations serve aviation (airports, helipads, ATC), highway and transportation (State DOTs), military and government agencies, environmental research institutions, and remote weather observation sites. Trusted customers include NASA, NOAA National Weather Service, the Federal Aviation Administration, the EPA, U.S. military branches, and multiple state Departments of Transportation across the USA and internationally.
