OWLETS-1: Ozone and Nitrogen Dioxide Measurements Over Chesapeake Bay

NASA's OWLETS-1 field campaign collected ozone and nitrogen dioxide data over the Chesapeake Bay from July 5 to August 3, 2017. It utilized a unique combination of instruments, including Pandora spectrometers, aircraft, lidars, and ship-based measurements, to characterize pollutant gradients across the land-water interface. The dataset was designed to address the challenge of measuring air quality in coastal transition zones.

Use Cases

• Analyzing ozone concentration gradients between land and water surfaces using synchronous vertical measurements.
• Studying nitrogen dioxide variations in coastal environments using Pandora spectrometer data.
• Validating atmospheric chemistry models with high-resolution, multi-instrument field campaign observations.
• Investigating fundamental processes at the land-water interface using mobile and fixed-site measurement comparisons.

Strengths

• Data collection is explicitly stated as complete across all sources.
• Campaign utilized a unique combination of instrumentation, including aircraft, lidars, drones, and ship-based measurements.
• Focused on a specific, challenging research problem: coastal air quality and land-water transitions.

Limitations

• Column names and data structure are unknown across all platform entries.
• Dataset size and row counts are not provided by any source.
• There is a conflict in the 'last updated' metadata between 2017-10-16 and 2026-04-09.
