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

3-hourly ensemble mean forecasts of surface PM2.5 Organic Carbon concentration over the continental United States and surrounding regions. The Hazardous Air Quality Ensemble System (HAQES) provides real-time forecasts for events like wildfires and dust storms, combining models from NASA, NOAA, and the Naval Research Laboratory. The prototype was developed by George Mason University as part of the NASA Health Air Quality Applied Science Team.

Use Cases

• Forecasting wildfire smoke impacts based on ensemble PM2.5 Organic Carbon concentration data.
• Analyzing regional air quality trends based on 3-hourly temporal resolution.
• Modeling atmospheric particulate matter transport based on multi-agency ensemble forecasts.
• Assessing public health exposure risks based on forecasted hazardous air quality events.

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.
• Covers the continental United States and surrounding regions on a Lambert projection.

Limitations

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