Air quality. Meteorology. Siting classifications for surface observing stations on land Ingestion-build-47553 A wide range collet is1 Scope This International Standard indicates exposure rules for various sensors, but what should be done when these conditions are not fulfilled? There are sites that do not respect the recommended exposure rules. Consequently, a classification has been established to help determine the given sites representativeness on a small scale (impact of the surrounding environment). Hence, a class 1 site can be considered as a reference site. A class 5 site
