SCOAPE2_Sondes_Data: Ozonesonde Profiles from Gulf of Mexico Air Quality Campaign

SCOAPE2_Sondes_Data contains vertical profile measurements of ozone collected by ozonesondes during the Satellite Coastal and Oceanic Atmospheric Pollution Experiment II (SCOAPE-II) in May 2024. This dataset supports the validation of satellite instruments like TEMPO and investigates the impact of offshore oil and gas activities on air quality. The campaign involved shipboard, ground-based, and aircraft measurements focused on the Gulf of America.

Use Cases

• Validating satellite-derived NO2 and ozone columns from the TEMPO instrument.
• Analyzing vertical ozone profiles to understand atmospheric transport and chemistry over the ocean.
• Assessing compliance with National Ambient Air Quality Standards (NAAQS) for offshore oil and gas operations.
• Studying pollutant plumes from offshore energy infrastructure in the Gulf of Mexico.

Strengths

• Data collection is explicitly stated as complete for this product.
• Supports a multi-platform field campaign (ship, ground, aircraft) for robust comparison.
• Generated under a formal interagency agreement between NASA and the Bureau of Ocean Energy Management (BOEM).

Limitations

• Column names and dataset size (rows, file size) are not specified in any source.
• Conflicting 'last updated' dates exist between platforms (2026-04-09 on Data.gov vs. 2024-06-13 on NASA Earthdata).
• Specific license terms under 'other-license-specified' are not detailed.
