Carbon monoxide (CO) Measurements

Carbon monoxide (CO) measurements were made nearly continuously from September 2004 through 2007 by the group of Professor Ian Faloona (UC Davis Dept. of Land, Air, & Water Resources). These high frequency (currently 1Hz) CO observations were acquired using an Aero-laser, AL5002 resonance fluorescence instrument. The general technique is described in Gerbig et al. [J. Geophys. Res., 104 (D1), 1699-1704, 1999] and the following performance characteristics are typical of the shoreline system at Bodega Bay:

  • Detection Rate/Frequency Response: >1 Hz
  • Precision (@ 1s & 100 ppb CO): ± 1.4 ppb
  • Accuracy: ± 2%
  • Detection Limit: < 1.5 ppb @ 1s
  • Linearity Range: 0 to >100 ppm

Calibrations using a standard from Scott Specialty (300-1500 ppbv CO in air) were done every 2 hours and zeros (CO scrubbed from ambient sample) are done approximately every hour. The data is available here as an ASCII text file and has been averaged to 30-minute points (both means and medians). Forty percent of the 1Hz data must be present for a data point to be reported, otherwise the number “-9999” is reported. The timestamp is reported as the Julian Day (and fraction thereof) of the year, for which the start of the year, midnight January first, is 1.0. CO concentrations are reported in units of parts per billion volume (ppbv). Corresponding meteorological data is also available for download here. For more information or requests for high frequency data please contact Dr. Ian Faloona or Dr. Douglas Day.

Ozone (O3) Measurements

The 1 hour ozone measurements were made with a Dasibi Model 1003-AH UV absorption instrument and presented at the center time of the averaged measurement interval. The instrument was calibrated before and after the deployment at Bodega Bay using the ambient measurements made by the California Air Resources Board in Davis, CA (ARB #57577) as a transfer standard. Queries about the data can be directed to Dr. Ian Faloona (UC Davis Dept. of Land, Air, & Water Resources).
