This quarterly report presents results and analysis of continuous onsite ambient fine particulate data at the North Birmingham sampling site during the October--December, 2001 study period. The continuous data include PM{sub 2.5} mass concentrations measured by TEOM, particle sulfate using the R&P 8400S monitor, particle size distributions measured by SMPS and APS monitors, and PM{sub 2.5} light scattering extinction coefficient as measured by nephelometer. The persistent daily trends described in the previous quarterly report are seen in the fall particulate data, superimposed on the seasonal trend toward lower concentrations in the cooler months. Some instrumental issues were noted with the APS and the sulfate monitoring instruments, as described in the main report
