LMOS Surface Mobile EPA-GMAP Ozone Data from the 2017 Lake Michigan Field Campaign

May through June 2017 data collected via the EPA GMAP mobile platform during the Lake Michigan Ozone Study (LMOS). This dataset contains trace gas surface mobile measurements aimed at understanding ozone formation and transport around Lake Michigan. It is a product of a multi-agency collaboration involving NASA, NOAA, EPA, EPRI, NSF, LADCO, and university research groups.

Use Cases

• Modeling ozone transport based on observed lake-shore concentration gradients.
• Analyzing the impact of lake breeze airflow on ozone levels based on mobile platform measurements.
• Improving chemical transport model forecasts for the Lake Michigan region based on field study data.
• Investigating rural ozone peaks far from emission sources as described in the study goals.

Strengths

• Data collection is complete for the May-June 2017 field campaign.
• Result of a joint effort across multiple authoritative agencies including NASA, NOAA, and the EPA.
• Designed to address a specific environmental challenge: elevated ozone levels exceeding NAAQS standards along the Lake Michigan coast.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Available file formats (BIN, PDF, ISO, HTML) suggest raw or packaged data that may require specialized tools to access.
