 Data are reported in the NOAA04A methane scale (Dlugokencky et al., 2005; updates at http://www.esrl.noaa.gov/gmd/ccl/ch4_scale.html). The link to this scale was established with 8 high pressure cylinders containing dry, natural air with a CH4 range of 690 - 1870 ppb. These standards were calibrated by NOAA on one or more occasions between 1987 and 2015. Stability of the CSIRO scale is monitored with ~25 assorted long-lived standards. Instrument response has been further evaluated with a suite of six Nippon Sanso CH4-in-air standards (volumetrically prepared, calibrated against a gravimetric scale at Tohoku University) spanning the range 310-1845 ppb. Pre-1992 data that were previously reported (Fraser at al., 1994, and references therein) in a scale derived from the scale used by the Oregon Graduate Institute (OGI) have been adjusted here to be consistent with the NOAA04A CH4 scale. Details of calibration and measurement uncertainty are given by Francey et al., 2003.
 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
