Observational Instrumentation

AOS® CO2 Airborne Analyzer System

The AOS® CO2 Airborne Analyzer System is a portable, fully automated, artifact-free, in-situ air sampler for the measurement of atmospheric carbon dioxide. It takes multiple forms, depending on the platform and scientific objectives. The forms are rack mount, fuselage, wing pod and modular. There are both manned and unmanned aircraft. AOS has a team of individuals that have taken the system from invention to full deployment in successful support of scientific missions. References are available upon request.
