LMOS: Lake Michigan Ozone Study Ground Site Data from 2017

The Lake Michigan Ozone Study (LMOS) ground site data was collected at the Illinois EPA site during a May-June 2017 field campaign. This multi-agency effort involving NASA, NOAA, EPA, and others aimed to understand ozone formation and transport around Lake Michigan. Data collection is complete and includes air quality and meteorology observations from fixed ground-based platforms.

Use Cases

• Analyzing ozone concentration gradients along the Lake Michigan shoreline based on the described lakeshore gradient phenomenon.
• Studying the relationship between onshore 'lake breeze' airflow and ozone levels based on meteorological data mentioned.
• Improving chemical transport model (CTM) forecasts for the region based on the study's stated long-term goals.
• Investigating spring and summertime ozone exceedances of the 2015 NAAQS standards based on the challenge described.

Strengths

• Data collection is complete for the May-June 2017 field campaign.
• Result of a collaborative, multi-agency effort involving NASA, NOAA, EPA, EPRI, NSF, LADCO, and university research groups.
• Designed to address a specific, observed environmental challenge: elevated ozone levels along the Lake Michigan coast.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Data is from a specific 2017 campaign; temporal coverage is limited to two months.
