NASA TRACE-P Project: Balloonsonde and Ozonesonde Data from the Pacific, 2001

March-April 2001 balloonsonde and ozonesonde data collected during the NASA TRACE-P suborbital campaign. The dataset was part of NASA's Global Tropospheric Experiment and involved multiple aircraft, ground stations, and satellites to study the chemical evolution of air masses from Asia over the western Pacific. Data collection for this product is complete.

Use Cases

• Modeling atmospheric transport of pollutants based on aircraft and ground station measurements.
• Analyzing chemical evolution of air masses based on trace gas and aerosol data.
• Studying ozone column and tropopause dynamics based on Differential Absorption Lidar (DIAL) measurements.
• Investigating aerosol properties and composition based on nephelometer and chromatograph instrument data.

Strengths

• Data collection involved multiple platforms, including two aircraft equipped with 19 and 21 instruments respectively.
• Campaign had specific, well-defined scientific goals for studying atmospheric chemistry over a key region.
• Dataset is part of NASA's long-term Global Tropospheric Experiment program.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
