Instrument 'PR1' mole fraction data supplied by I.J. Vimont (isaac.vimont@noaa.gov, 303.497.6044) from instrument PERSEUS-1 GC/MS analysis of stainless steel and/or glass flask pairs collected at the HATS remote sites. All mole fraction (*_C) and pair standard deviation (*_sd, 95% confidence interval) data reported as dry gas mole fractions in the following units and scale: Units: parts-per-trillion (ppt) Scale: NOAA-2018-PR1 |

[Hourly] [Daily] [Monthly] |
|
|
All mole fraction data have been filtered to require: a) two aliquots per flask with differences <= 0.2 ppt (95% confidence interval), and b) flask pair differences <= 0.2 ppt (95% confidence interval). All known analytical and/or sampling problem data have been omitted. Data which appear anomalously high or low, but for which we do not know of any analytical or sampling issues, have been given a '>' or '<' flag symbol, respectively, in an effort to produce our best guess as to the background values, which are denoted with flag '-'. |
