Methods-comparison measurements during the Carbonaceous-Species Methods Comparison Study, Glendora, California, August 1986: tunable-diode laser absorption spectrometer measurements of HCHO, H/sub 2/O/sub 2/ and HNO/sub 3/. Final report

As part of the Carbonaceous-Species Methods Comparison Study at Citrus College, Glendora CA, on August 11-21, 1986, Unisearch Associates participated in methods evaluation studies for formaldehyde (HCHO), hydrogen peroxide (H/sub 2/O/sub 2/) and nitric acid (HNO/sub 3/). These three species play important roles in photochemistry of urban and rural air, and their measurements provide sensitive tests for current acid deposition and urban smog models. Two tunable diode laser absorption spectrometers (TDLAS) were used in the methods evaluation study.
