Southern California Air Quality Study (SCAQS) description of measurement activities. Final report

Technical Report ·
OSTI ID:6971422
The goal of the Southern California Air Quality Study (SCAQS) was to develop a data base for the Los Angeles Basin that can be used to test, evaluate, and improve models for oxidants, PM10, fine particles, toxic air contaminants, and acidic species. In addition, SCAQS data will be used to address questions regarding the emission, transport, transformation, and deposition of pollutants. The report documents the SCAQS measurements which were conducted in the Los Angeles Basin over 13 weeks in the summer and fall of 1987. Routine air quality and meteorology measurements were made continuously throughout the study period. On 17 selected intensive study days, measurements were made at several locations throughout the Basin of: reactive and toxic gases (including PAN, H2O2, speciated hydrocarbons, and carbonyls), aerosol chemistry, aerosol size distribution, selected aerosol chemical species as a function of size, and light scattering and extinction. LIDAR backscatter and aerosol and reactive gas measurements were also made by aircraft.
