Drought-2018 atmospheric CO2 Mole Fraction product for 48 stations (96 sample heights)

Atmospheric Greenhouse Gas Mole Fractions of CO2 collected by the Drought-2018 team, covering the period 1972-2018. Final quality controlled Level 2 data. During the most recent period, a selected set of stations, after being labelled as ICOS stations, follow the ICOS Atmospheric Station specification V1.3. Measurements and data processing for all time series is described in the paper below. All concentrations are calibrated to the WMO X2007 CO2 mole fraction scale in µmole/mole (ppm).
