| Zusammenfassung |
| We present descriptions of the in situ instrumentation, calibration
procedures, intercomparison efforts, and data filtering methods used in a
39-yr record of continuous atmospheric carbon dioxide (CO2)
observations made at Baring Head, New Zealand. Located on the southern coast
of the North Island, Baring Head is exposed to extended periods of strong
air flow from the south with minimal terrestrial influence resulting in low
CO2 variability. The site is therefore well suited for sampling air
masses that are representative of the Southern Ocean region. Instrumental
precision is better than 0.015 ppm (1-σ) on 1-Hz values. Comparisons to
over 600 co-located flask samples, as well as laboratory based flask and
cylinder comparison exercises, suggest that over recent decades
compatibility with respect to the Scripps Institution of Oceanography (SIO)
and World Meteorological Organisation (WMO) CO2 scales has been 0.3 ppm
or better. |
