LMOS UC-12: Aircraft Meteorological and Navigational Data

May through June 2017 data was collected onboard a NASA UC-12 aircraft during the Lake Michigan Ozone Study (LMOS) field campaign. The dataset contains in-situ meteorological and navigational measurements aimed at understanding ozone formation and transport gradients around Lake Michigan. It resulted from a multi-agency collaboration involving NASA, NOAA, EPA, EPRI, NSF, LADCO, and university research groups.

Use Cases

• Analyzing the relationship between lake breeze patterns and ozone concentrations based on in-situ meteorological data.
• Validating chemical transport model (CTM) forecasts for ozone using observed aircraft data.
• Investigating the spatial gradient of ozone levels from the lakeshore inland using geospatial flight track data.
• Studying spring and summertime ozone exceedances of the 2015 NAAQS standards in the Lake Michigan coastal region.

Strengths

• Data collection is explicitly stated as complete, providing a finalized observational record.
• Represents a collaborative effort across multiple major federal and state agencies, suggesting a high level of coordination and review.
• Supports a specific, well-documented scientific goal: understanding the lakeshore ozone gradient phenomenon.

Limitations

• Column names and a precise row count are not provided by any source, limiting assessment of data structure and volume.
• Conflicting 'last updated' dates exist (2017-06-28 and 2026-04-10), creating uncertainty about metadata maintenance.
• The license is listed as 'other-license-specified' without details, requiring further investigation for reuse.
