December 2000 to February 2002 data on airborne particle size distributions in the Los Angeles Basin. Measurements were taken at four sites using a Scanning Mobility Particle Sizer (SMPS) that recorded particle count concentrations across 54 to 108 size channels every 15 minutes. The data was collected by the NARSTO and EPA Supersites Program, managed by the LARC_ASDC.
Use Cases
- Analyze temporal patterns in particle_count_concentration across 54-108 size_channels from 0.014 to 0.673 mm at 15-minute intervals.
- Model the relationship between particle_size_distribution and geographic location using data from Claremont, Downey, Riverside, and Rubidoux sites.
- Characterize source contributions to airborne particulate_matter by examining diurnal and seasonal trends in the multi-year monitoring record.
Strengths
- Over one year of continuous monitoring from December 2000 to February 2002.
- High temporal resolution with measurements recorded every 15 minutes.
- Data covers four distinct geographic sites within the Los Angeles Basin.
Limitations
- Dataset is temporally stale, with the last update in February 2002.
- Specific row count, file size, and data completeness metrics are unknown.
- Geographic coverage is limited to four locations within a single metropolitan area.
