Atmospheric trace gas data from the CONTRAIL flask air sampling over the Pacific Ocean

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).
