DISCOVER-AQ Maryland Deployment Aldino Ground Site Data

Maryland deployment data collected at the Aldino ground site during NASA's DISCOVER-AQ field study. The dataset likely contains surface-level measurements of aerosol properties, meteorological variables, and trace gas species, collected in conjunction with aircraft observations to validate satellite data. NASA Langley Research Center, NASA Goddard Space Flight Center, NASA Ames Research Center, and multiple universities collaborated on this four-year campaign to improve satellite monitoring of air quality.

Use Cases

• Validate satellite column observations of ozone, nitrogen dioxide, and formaldehyde based on surface-level measurements.
• Analyze diurnal variability of pollutants based on ground and aircraft data.
• Model urban plume dynamics and pollution gradients based on targeted observations in violation areas.
• Correlate aerosol properties and meteorological variables with trace gas concentrations.

Strengths

• Data collection is complete for the Maryland deployment.
• Incorporates measurements from multiple platforms: ground sites, two NASA aircraft (P-3B and King Air), and existing monitoring networks.
• Campaign targeted regions in violation of National Ambient Air Quality Standards.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is specific to the Maryland deployment and does not include other campaign regions.
