 Instrument 'PR1' mole fraction data supplied by B. R. Miller (ben.r.miller@noaa.gov, 303.497.6624)
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-2016-PR1
 [Hourly]
 [Daily]
 [Monthly]
 All mole fraction data have been filtered to require:
a) two aliquots per flask with differences <= 0.06 ppt (95% confidence interval), and
b) flask pair differences <= 0.06 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 '-'.
