During the summer and fall of 1987 the State of California Air Resources Board coordinated the Southern California Air Quality Study (SCAQS) in the greater Los Angeles area to address ozone, nitrogen dioxide and the role of nitrogen oxides, PM-10, fine particles, visibility, toxic air contaminants and atmospheric acidity. Measurements discussed in the report were made during the summer in Claremont and during the fall in Long Beach, which represented 'A-site' receptor and source regions respectively. The tunable diode laser absorption spectrometer (TDLAS) system was employed for the real time measurements of gas-phase hydrogen peroxide and formaldehyde. The system obtained a data point for both species every minute. Results were subsequently reduced to 1-hour average values for comparison with measurements made by other methods.
