ICOS atmospheric station Observational timeseries of ambient mole fraction of CO in dry air, composed of (all whenever available) historical PI quality-checked data, ICOS Level 2 data, ICOS FastTrack data and ICOS NRT data. The following uncertainty estimates are used: a. Continuous Measurement Repeatability: monthly average of the standard deviations of short-term target raw data over 1-minute intervals b. Long Term Repeatability: standard deviation of the averaged short-term target measurement intervals (of 10 minutes every 5 hours approximately) over three days c. Short Term Target Bias: difference between the hourly average of the short-term target injections and the value assigned by the calibration lab The method used for "value_unc_1" is "Continuous Measurement Repeatability". The method used for "value_unc_2" is "Long Term Repeatability". The method used for "value_unc_3" is "Short Term Target Bias". More information about the uncertainty estimates can be found in Yver Kwok et al. (2015) (https://doi.org/10.5194/amt-8-3867-2015) and Yver-Kwok et al.
