<abstract>
<p>An automated gas chromatograph with sample pre-concentration for the
measurement of peroxyacetylnitrate (PAN) was constructed with a minimum
detection limit below 1 pptv. This instrument was deployed at the British
Antarctic Survey&apos;s Halley Research Station, Antarctica (75.6&amp;deg; S, 26.6&amp;deg; W)
as part of the CHABLIS (Chemistry of the Antarctic Boundary Layer
and the Interface with Snow) campaign. Hourly measurements were carried out
between July 2004 and February 2005 with observed maximum and minimum mixing
ratios of 52.3 and &amp;lt;0.6 pptv, respectively with a mean PAN mixing ratio
for the measurement period of 9.2 pptv (standard deviation: 6.2 pptv). The
changes in PAN mixing ratios typically occurred over periods of several days
to a week and showed a strong similarity to the variation in alkenes. The
mixing ratio of PAN at Halley has a possible seasonal cycle with a winter
maximum and summer minimum, though the cycle is incomplete and the data are
very variable. Calculations indicate that gross local PAN production is
approximately 1 pptv d&lt;sup&gt;&amp;minus;1&lt;/sup&gt; in spring and 0.6 pptv d&lt;sup&gt;&amp;minus;1&lt;/sup&gt; in summer. Net
loss of PAN transported to Halley in the summer is a small gas-phase source
of NOx and net production of PAN in the spring is a very small NOx sink.</p>
