Data Clearinghouse

Download model input and output (I/O) data for SMOKE, CMAQ, and MM5 from the CMAS Data Clearinghouse. Links to observational data and other model I/O are also provided. With the Data Clearinghouse in its early stages, the CMAS Center is currently only providing links to tutorial and benchmark datasets. Plans to provide more comprehensive datasets are underway.

CMAS is facilitating the creation of a metadata standard for the air quality and emissions modeling communities with the intent of establishing a national data grid for atmospheric data. With the establishment of such a standard, the CMAS will enable the atmospheric modeling arena to access a shared database across a widely distributed user community.

Available Data: Data Search Engines | Modeled Data | Emissions | Observational | Remote Sensing

Data Search Engines

• EPA Data Finder - Data Finder is a single place to find EPA's data sources so people can access and understand environmental information.

Modeled Data

• CMAS Data Search Engine - online portal for accessing model output data produced by the CMAS community

Emissions data

• RPO Emissions Inventories - links to sites that provide access to the emissions inventories being modeling by the US Regional Planning Organizations
• US EPA Clearinghouse for Inventories and Emissions Factors - online database of emissions inventories, emissions factors, and emissions modeling inputs available through the US EPA. Resources include the National Emissions Inventory (NEI), pollutant emissions trends, inventory software & tools, and emissions modeling factors, such as spatial surrogates and temporal profiles.
• Candian emissions inventories - the Canadian National Pollutant Release Inventory (NPRI) for current and past years. The NPRI is a database of information on annual releases to air, water, land and disposal or recycling from all Canadian emissions sectors - industrial, government, commercial and others.
• Mexican emissions inventories - Big Bend Regional Aerosol & Visibility Observational Study (BRAVO) emissions inventory contains emissions data for 10 states in Mexico (San Luis Potosi, Baja California Norte, Sonora, Chihuahua, Coahuila de Zaragoza, Nuevo Leon, Tamaulipas, Sinaloa, Durango, and Zacatecas) and offshore platforms in the Gulf of Mexico. The emissions inventory for Mexico is the first regional scale inventory for this area.
• Global Emissions Inventory Activity - GEIA -- an integrating project of AIMES/International Geosphere-Biosphere Program -- Brings together people, data and tools to create highest quality information on global exchange processes.
