HAQES_NA_PM25_TOT_CENSUS: 3-Hourly PM2.5 Forecasts for the Continental U.S.

HAQES 3-hourly ensemble mean surface total PM2.5 concentration data at the census level over the continental United States. The Hazardous Air Quality Ensemble System (HAQES) is a real-time forecast system for events like wildfires and dust storms, developed by the George Mason University Air Quality Laboratory as part of the NASA HAQAST team. It integrates models from NASA, NOAA, the Naval Research Laboratory, and other agencies.

Use Cases

• Modeling public exposure to particulate matter based on census-level spatial resolution.
• Forecasting hazardous air quality events like wildfires based on the ensemble model system.
• Analyzing temporal patterns of PM2.5 concentration based on the 3-hourly forecast data.
• Validating and comparing different atmospheric chemistry models based on the multi-agency ensemble.

Strengths

• Data is produced by a multi-agency ensemble including NASA, NOAA, and the Naval Research Laboratory.
• Provides real-time forecasts for hazardous air quality events.
• Spatial resolution is at the census level for the continental United States.

Limitations

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