HAQES: 3-Hourly Ensemble Forecast of Surface PM2.5 Black Carbon over North America

HAQES provides 3-hourly ensemble mean surface PM2.5 Black Carbon concentration forecasts over the continental United States and surrounding regions. The Hazardous Air Quality Ensemble System is a real-time forecast system for events like wildfires and dust storms, developed by the George Mason University Air Quality Laboratory for NASA's HAQAST. It combines models from NASA, NOAA, the Naval Research Laboratory, and others.

Use Cases

• Modeling real-time hazardous air quality events based on ensemble forecasts for wildfires and dust storms.
• Analyzing spatial patterns of PM2.5 Black Carbon concentration over North America based on the mapped Lambert projection data.
• Comparing and validating multi-agency atmospheric models based on the ensemble system combining GEOS, NAAPS, GEFS, and other sources.
• Assessing public health exposure to particulate matter based on forecasted surface concentration data.

Strengths

• Data is produced by a multi-agency ensemble system including NASA, NOAA, and the Naval Research Laboratory.
• Provides real-time 3-hourly forecasts for hazardous air quality events.
• Covers the continental United States and surrounding regions with geospatial mapping.

Limitations

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