Short summary
Data on atmospheric trace gases have been collected with instruments on-board a commercial airliner for more than 10 years in the CARIBIC project. We investigate which species in the dataset can be used for a representative climatology, by comparing data from the chemistry–climate model EMAC along the flight paths to a larger set of model data. We find that long-lived species are captured quite well by the CARIBIC sample while this is not the case for more variable, shorter-lived species.
