SONEX Satellite Data: Ozone and Wind Measurements from the 1997 North Atlantic Campaign

SONEX_Satellite_Data contains satellite-derived ozone and wind measurements supporting the 1997 Subsonics Assessment Ozone and NOx Experiment (SONEX). The data, collected from TOMS-EP and GOES-8 instruments, was used to study the impact of aircraft emissions on atmospheric composition in the North Atlantic Flight Corridor. The international campaign involved NASA and German DLR aircraft and targeted meteorological events like convection and stratospheric intrusions.

Use Cases

• Analyzing ozone column density perturbations from aircraft emissions using TOMS-EP data.
• Studying wind dynamics and their role in pollutant transport using GOES-8 wind measurements.
• Modeling the impact of nitrogen oxides (NOx) and hydrocarbons on upper tropospheric/lower stratospheric ozone.
• Investigating the relationship between convection, lightning events, and atmospheric composition changes.

Strengths

• Data originates from a well-documented, international scientific campaign involving NASA and DLR.
• Supports analysis of multiple atmospheric components, including ozone, NOx, aerosols, and wind dynamics.

Limitations

• Specific column names and dataset size (rows, file size) are not provided by any source.
• Conflicting last-updated dates exist between sources (1997-11-17 and 2026-04-09), creating uncertainty about metadata freshness.
• Documentation gaps exist regarding the exact structure and format of the satellite data files.
