Atmospheric Flask CO2 and Isotopic Data - Multiple Sampling Stations. In Scripps CO2 Program Data

Atmospheric flask CO2 and isotopic data sets taken at 14 sampling stations. The stations ALT, PTB, LJO, MLO, KUM, CHR, SAM, KER, NZD, SPO are active and generate ongoing data sets, which will be updated when new data is available. The stations STP, BCS, FAN, and PSA are no longer active, but are included here as legacy station data.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 "), as well as monthly averages. 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.
