Atmospheric Greenhouse Gas Mole Fractions of CO2 collected by the Drought-2018 team, covering the period 1979-2018. Final quality controlled Level 2 data, release 2019-1. During the most recent period, a selected set of stations, after being labelled as ICOS stations, follow the ICOS Atmospheric Station specification V1.3 (https://www.icos-ri.eu/fetch/ba12290c-3714-4dd5-a9f0-c431b9900ad1;1.0). Measurements and data processing for all time series is described in Ramonet, 2019 (doi:xxxxx). All concentrations are calibrated to the WMO X2007 CO2 mole fraction scale in µmole/mole (ppm).
