Successful carbon monoxide monitoring over long paths was performed during the 1975 Regional Air Pollution Study (RAPS) of the U.S. Environmental Protection Agency. Over 40 days of monitoring were carried out at Regional Air Monitoring Station (RAMS) Sites 108 and 105. These data were analyzed with assigned error bars, and are presented on 24-hour daily plots. Correlations with meteorological data are continuing in order to obtain relevant information for pollution modeling. Some unexpected problems in calibration drift, non-linearity and interference were encountered this year, but they were successfully minimized in the field. As these problems were caused, in part, by use of some of the first commercially-produced diode lasers, they were expected to diminish as more satifactory manufacturing techniques are developed.
