OWLETS-2: Surface Air Quality and Meteorology Over Chesapeake Bay

OWLETS2_Surface_Data_1 contains in-situ and remote sensing measurements from the NASA-funded Ozone Water-Land Environmental Transition Study (OWLETS-2) field campaign. The dataset captures ozone concentrations, pollutant gradients, and meteorological variables across land-water boundaries in the Chesapeake Bay region. It was collected from three primary research sites to study fundamental atmospheric processes at the coastal interface.

Use Cases

• Analyzing ozone concentration gradients between land and water based on synchronous vertical measurements.
• Studying the impact of coastal meteorology on pollutant transport using wind, temperature, and humidity data.
• Validating satellite or aircraft-based remote sensing observations with ground-based in-situ measurements.
• Modeling atmospheric chemistry and boundary layer processes in a complex coastal environment.

Strengths

• Data originates from a NASA Science Innovation Fund (SIF) campaign, ensuring institutional rigor.
• Campaign utilized a unique multi-platform approach including lidars, drones, ozonesondes, and ship-based measurements.
• Provides synchronous measurements over land and water from specifically established research sites.

Limitations

• Column names and dataset size (row count, file size) are not specified in any source.
• Conflicting 'last updated' metadata between platforms (2018-08-02 on NASA Earthdata vs. 2026-04-09 on Data.gov).
• License is ambiguously listed as 'other-license-specified' without details.
