DISCOVER-AQ Texas Deployment Ozonesonde Data

Ozonesonde launch data from the Moody Tower and Smith Point ground sites during NASA's DISCOVER-AQ Texas deployment in Houston. The campaign was a four-year collaboration between NASA Langley, Goddard, Ames Research Centers and multiple universities to improve satellite monitoring of air quality. Data collection is complete for this deployment.

Use Cases

• Validate satellite column observations of ozone based on surface-level measurements.
• Analyze diurnal variability of trace gases based on surface-level measurements.
• Investigate correlations between surface and column observations for ozone, nitrogen dioxide, and formaldehyde.
• Explore horizontal scales of variability, such as urban plumes and steep gradients.

Strengths

• Data collection is complete for the Texas deployment.
• Part of a four-year NASA campaign involving multiple research centers and universities.
• Incorporates measurements from aircraft, ground-based platforms, and existing monitoring networks.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• File formats include BIN, PDF, ISO, HTML; data accessibility may require specific tools.
