DISCOVER-AQ Colorado Ozonesonde Data for Satellite Validation

DISCOVER-AQ Colorado Ozonesonde Data contains measurements from ozonesonde launches at the Platteville ground site during NASA's 2014 Denver deployment. The data was collected as part of a four-year campaign involving NASA Langley, Goddard, and Ames Research Centers, along with multiple universities, to improve satellite monitoring of air quality. The campaign targeted regions, including Denver in 2014, that violated the National Ambient Air Quality Standards.

Use Cases

• Validate satellite column observations of ozone based on surface-level ozonesonde measurements.
• Analyze diurnal variability of atmospheric pollutants based on targeted ground and aircraft observations.
• Investigate correlations between surface pollution and satellite data for nitrogen dioxide and formaldehyde.
• Model horizontal scales of variability, such as urban plumes, using multi-platform measurement data.

Strengths

• Data collection is complete for the Colorado deployment, providing a finalized dataset.
• Integrates measurements from ozonesondes, aircraft, and ground sites for multi-platform validation.

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.
