SEAC4RS: Atmospheric Profile Data from Radiosonde and Ozonesonde Launches

Data from nine ground locations in the southern and central United States, including Houston, TX, and Boulder, CO, collected during the August-September 2013 SEAC4RS airborne field study. The dataset contains vertical profile measurements from ozonesonde and radiosonde launches, likely capturing atmospheric composition, wind, and humidity. It was designed to study pollutant redistribution by convection, aerosol-climate interactions, and to validate future satellite instruments.

Use Cases

• Analyzing vertical profiles of ozone concentration based on ozonesonde measurements.
• Studying wind speed and direction at different atmospheric levels based on radiosonde data.
• Investigating the evolution of gases and aerosols in convective outflow as described in the study objectives.
• Calibrating satellite-derived atmospheric data using the in-situ sonde profiles.
• Modeling the redistribution of anthropogenic and biomass burning emissions via deep convection.

Strengths

• Data collection is explicitly stated as complete, providing a finalized record.
• Covers a specific, intensive field campaign (SEAC4RS) with a clear temporal focus (August-September 2013).
• Supports cross-platform validation, being hosted on both NASA Earthdata and Data.gov.

Limitations

• Column names and data structure are unknown, hindering precise technical assessment.
• Conflicting 'last updated' metadata (2013 vs. 2026) suggests potential metadata management issues.
• Specific row counts, file sizes, and detailed licensing terms are not provided.
