Measurements of H2O2 and HCHO by Tunable Diode Laser Absorption Spectroscopy During the 1986 Carbonaceous Species Methods Comparison Study in Glendora, California

and HCHO with a time response of 3 minutes per data point. The minimum detection limits were respectively 0.1 ppbv and 0.15 ppbv for HCHO and H

O

and the estimated accuracies were ± 20% for both species. During the first 5 days of the study H

showed little diurnal variation ranging between 0.25 and 0.5 ppbv with maximum values occurring at 15:30 PDT. During the final 4 days H

O

showed stronger diurnal behavior with mixing ratios ranging from below the detection limits during some nighttime periods to as high as 1.8 ppbv during midday maxima which occurred about 15:30 PDT. HCHO showed strong diurnal behavior throughout the study with rapid changes in concentration in the early morning and evening. Mixing ratios were typically in the range 5-20 ppbv with maxima at about 10:00 and 14:00 PDT. |
