Topic 3d - Part 1: Measurements from aircraft - overview of IAGOS

Commercial passenger aircraft have also been successfully utilised for taking atmospheric measurements. Using commercial aircraft has made it possible to carry out observations of atmospheric composition on a scale that would be impossible to achieve using research aircraft.

IAGOS (In-service Aircraft for a Global Observing System) project has a fleet of 9 aircraft made up of Lufthansa, China airlines, Hawaiian Airlines, Cathay Pacific, and Air France planes. These aircraft were fitted with instrumentation which take regular in situ measurements of atmospheric chemical species (O3, CO, CO2, CH4, NOx, NOy, H2O) 1 , aerosols and cloud particles.

IAGOS data are being used by researchers worldwide for process studies, trend analysis, validation of climate and air quality models, and the validation of space borne data retrievals.
