| Data are reported in the CSIRO2020 CO scale, which is related to the previously used CSIRO1994 CO scale by a constant factor of 1.03 (i.e. CSIRO2020 is higher than CSIRO1994 by exactly 3%). The CSIRO2020 scale is maintained using ~20 high-pressure cylinder standards, spanning a CO range of ~29–487 ppb. The long-term stability and internal consistency (i.e. relative mole fraction across the calibrated range) are defined by CSIRO’s internal calibration systems and are fully independent of the WMO X2014A scale. However, the absolute level of the CSIRO2020 scale is aligned with the WMO X2014A CO scale on the basis of NOAA measurements of 8 of CSIRO’s standards in 2015/16. Preliminary assessment of these data suggests the scales are consistent to within +/- 1 ppb over the calibrated range of the CSIRO scale. | |
| Flask data are assigned flags to indicate whether they are classified as retained or rejected. Cause of rejection falls into three broad categories: (i) the sample is considered to be not representative of the atmosphere at the time and place of sampling due to identified or inferred sampling or analytical problems (eg. sample contamination, poor analysis), (ii) the sample is considered to be “non-baseline” as indicated by the meteorological conditions at the time of sampling and (iii) any remaining outliers are flagged on the basis of a 3-sigma filter (geographically fixed sites only). For completeness, all data are included here, regardless of whether they are retained or rejected. Please note that for routine “baseline” applications, any rejected data must be actively excluded from the provided data sets, while for “non-baseline” applications data flagged under categories (ii) and (iii) above may carry biogeochemical information (see DATA FORMAT section below). Also, further data selection may be desirable for those data sets that cannot be screened by the 3-sigma filter (e.g. AIA; aircraft). | |
|
[Hourly] [Daily] [Monthly] Monthly means are calculated as the mean of daily values from a smooth curve fit to the baseline data (with flags "...") using the curve-fitting routines described by Thoning et al., JGR, 1989. The std devs for the monthly means are calculated from the std dev of the monthly mean from the daily smooth curve values and the std dev of the residuals of each data point about the smooth curve for that month. |
|
|
flags: "..." indicates no flags, sample retained. Any entry other than "." in the first flag column indicates the sample is not representative of the time and place of sampling: A = no sample taken B = sample lost before analysis C = identified sampling error D = suspected sampling problem (eg. 2 or more species give anomalous values) E = mixed samples (time/place not unique) N = unacceptable analysis * = no analysis data available H = species-specific manually applied rejection flag I = species-specific sample collection problem J = irretrievable sample storage effect . = not subject to any of the above flags Any entry other than ""."" in the second flag column indicates the sample is non-baseline, rejected only on grounds of being an outlier or is excluded from this data set because of a non-standard sampling technique. F = non-baseline meteorological conditions G = marginal-baseline meteorological conditions K = species-specific non-baseline meteorological conditions L = species-specific marginal-baseline meteorological conditions M = 3 sigma filter rejected O = non-standard sampling technique . = not subject to any of the above flags |
