September 2024 in-situ aerosol data collected at the Marina Tower ground site during the PACE-PAX campaign. The dataset features measurements from instruments including an Aerodynamic Particle Sizer, Ultra-High Sensitivity Aerosol Spectrometer, Nephelometer, and Printed Optical Particle Spectrometer. It was produced by the LARC_CLOUD organization for validating the PACE satellite mission.
Use Cases
- Validate PACE satellite aerosol optical depth retrievals using collocated ground-based nephelometer scattering data.
- Analyze aerosol size distribution from APS and UHSAS instruments to characterize particle populations in coastal California.
- Assess temporal variability in aerosol properties from time-series data to inform satellite overpass validation strategies.
- Correlate in-situ particle spectrometer (POPS) data with satellite observations during high-aerosol load events.
Strengths
- Data collection is complete for the September 2024 campaign period.
- Integrates measurements from four specialized aerosol instruments (APS, UHSAS, Nephelometer, POPS).
- Designed specifically for the validation objectives of the PACE satellite mission.
Limitations
- Sample size and temporal coverage are limited to a single month in 2024.
- Geographic scope is restricted to Southern and Central California coastal regions.
- Unknown row count and data granularity (e.g., minute vs. hour intervals).
