Southern and Central California airborne campaign data from September 2024, collected to validate the PACE satellite mission. The In-Situ Aerosol Retrieval Algorithm (ISARA) analysis data was gathered onboard a CIRPAS Twin Otter aircraft. The campaign involved 60 planned flight hours for the Twin Otter, coordinating with satellite overpasses and ground observations.
Use Cases
- Validate PACE satellite aerosol optical depth retrievals using in-situ ISARA measurements from the Twin Otter.
- Assess spatial and temporal scale impacts on validation by comparing aircraft flight tracks with satellite overpass times and locations.
- Identify potential measurement biases by analyzing data collected under specific geometries and during high-aerosol load conditions over land and ocean.
- Refine aerosol retrieval parameters by correlating ISARA analysis data with ground-based and other airborne instrument observations from the campaign.
Strengths
- Data collection is complete, providing a finalized dataset for the September 2024 campaign.
- Campaign involved coordinated measurements between aircraft, satellite overpasses, and ground observations for robust validation.
- Focused validation objectives target specific processes like high-aerosol loads and multiple aerosol layers.
Limitations
- Specific data volume (rows, file size) and column details are not provided, limiting initial assessment.
- Geographic coverage is limited to Southern and Central California and nearby coastal regions from a single month.
- The dataset's utility is temporally specific to the PACE satellite validation context.
