OWLETS-1: Ozone Lidar Measurements Over Chesapeake Bay

Twelve intensive measurement days from July 5 to August 3, 2017, captured vertical ozone profiles over land and water. The OWLETS-1 campaign used TOLNet lidars, aircraft, drones, and ship-based instruments to measure pollutant gradients across the Chesapeake Bay. This dataset likely contains synchronous vertical measurements of meteorology and pollutants from two primary sites: NASA Langley Research Center and the Chesapeake Bay Bridge Tunnel.

Use Cases

• Analyzing vertical ozone gradients over coastal water-land boundaries.
• Studying the impact of coastal meteorology on pollutant transport and mixing.
• Validating and improving regional air quality models for coastal environments.
• Investigating diurnal and synoptic-scale ozone variability over the Chesapeake Bay.

Strengths

• Data collection utilized a unique combination of instruments, including TOLNet ozone lidars, aircraft, and drones.
• Campaign established two synchronous measurement sites specifically to capture land-water pollutant gradients.
• Dataset is part of a multi-platform field campaign (OWLETS-2 followed in 2018), suggesting a structured research effort.

Limitations

• Column names and data structure are not specified in any source, limiting understanding of the specific variables.
• Conflicting license information exists between platforms (other-license-specified vs. None).
• Dataset size and row counts are unknown across all sources.
