OWLETS-2: Aircraft Atmospheric Measurements Over Chesapeake Bay

OWLETS-2_UMDAircraft_Data contains atmospheric measurements from a field campaign over the Chesapeake Bay. The Ozone Water-Land Environmental Transition Study (OWLETS-2) collected data on trace gases, greenhouse gases, aerosols, and aircraft navigation using remote sensing and in-situ instruments onboard a University of Maryland Cessna and an HU-25A aircraft. The campaign aimed to characterize pollutant gradients across the land-water interface from July 5 to August 3, 2017.

Use Cases

• Analyzing ozone concentration gradients between land and water based on in-situ and remote sensing measurements.
• Studying the correlation between trace gases and meteorological conditions using aircraft navigational data.
• Validating satellite precursor instruments like GeoTASO with coordinated ground and airborne observations.
• Modeling atmospheric processes at coastal boundaries using synchronous vertical profiles from two research sites.

Strengths

• Data collection is explicitly stated as complete, providing a finalized dataset.
• Campaign utilized a unique multi-platform approach, including aircraft, lidars, drones, and ship-based measurements.
• Features data from the GeoTASO instrument, a precursor to the operational TEMPO satellite.

Limitations

• Column names and data schema are unknown, hindering immediate analysis.
• Conflicting 'last updated' dates (2018 and 2026) across platforms create uncertainty about metadata freshness.
• Specific row counts, file sizes, and detailed licensing terms are not provided.
