Atmospheric Flask O2/N2 and CO2 Data Sets – Multiple Sampling Stations. In Scripps O2 Program Data

Atmospheric flask O2/N2 and CO2 data sets taken at 12 sampling stations. The stations ALT, BRW, CBA, LJO, MLO, KUM, SAM, CGO, PSA, SPO are active and generate ongoing data sets, which are updated when new data is available. The stations MCQ, and NWR are no longer active, but are included here as legacy station data. The data are provided as replicate averages of flasks collected on a given date ("daily "). The resolution of the replicate averages depends on sampling frequency, which is station dependent, typically between weekly and fortnightly (once every two weeks).

These data are subject to revision based on recalibration of standard gases.
