Onboard measurement system of atmospheric carbon monoxide over the Pacific Ocean by voluntary observing ships.

The article presents a study which aims to describe the onboard measurement system of atmospheric carbon monoxide (CO) over the Pacific Ocean by the U.S. National Institute for Environmental Studies (NIES). The study compared data from onboard performance of CO measurement system on commercial cargo vessels and laboratory analyses of flask samples using gas chromatography. Results show the good performance of both methods and usefulness of continuous measurement system in polluted air.
