Atmospheric carbon dioxide records from sites in the NOAA/CMDL air sampling network

BERMUDA (EAST)

Trends

The sampling site on the eastern end of the island of Bermuda at St. David's Head is operated as part of the Atmosphere/Ocean Chemistry Experiment (AEROCE). The first NOAA/CMDL flask air samples from St. David's Head were collected in early 1989. Since 1990, annual mixing ratios have risen from 355.2 parts per million (ppm) to 357.1 ppm in 1992. This 1992 annual mixing ratio is comparable to other North Atlantic measurements (e.g., 356.5 ppm at Station "M"). The atmospheric CO mixing ratio records from Bermuda show a seasonal pattern: minimum mixing ratios are measured during the late northern summer, and maximum values, during the late winter and early spring.
