Atmospheric trace gas data from the CONTRAIL flask air sampling over the Eurasian continent (most recent data)

The update of this dataset has stopped, because the data is merged into the all-route dataset. This data set contains trace gas mole fractions observed over the Eurasian continent by the flask air sampling of the CONTRAIL (Comprehensive Observation Network for TRace gases by AIrLiner) project. Air samples were collected by the Automatic air Sampling Equipment (ASE) and manually by the Manual air Sampling Equipment (MSE) on board commercial aircraft of Japan Airlines (JAL). This data set consists of observational data between Tokyo and Paris, and Tokyo and Moscow. This data set contains the most recently obtained data, whose QA/QC is still in progress. Because of this, the citation policy and format are different from those of the regular data (Machida et al., 2019). Please read carefully the citation policy written below. Furthermore, a password is required to download the data, which can be obtained by contacting the CONTRAIL PIs ([e-mail]). Note that these data will be merged into the regular data set at the next major update.
