This page is intended for users experienced with air quality modeling using the EPA's Fused Air Quality Surfaces Using Downscaling Tool and the Community Multi-scale Air Quality (CMAQ) model.
Fused Air Quality Surface Using Downscaling (FAQSD) Files
A Bayesian space-time downscaler model is based on statistical modeling research in the development of fused space-time predictive surfaces for air quality.
A Bayesian space-time downscaler model is used to "fuse" daily ozone (8-hr max) and fine particulate air (24-hr average) monitoring data from the National Air Monitoring Stations/State and Local Air Monitoring Stations (NAMS/SLAMS) with 12 km gridded output from the Models-3/Community Multiscale Air Quality (CMAQ) model.
Daily predictions are available at the 2010 US Census Tract centroid locations for 2002-2012.

CMAQ Input Files
The EPA CMAQ model-gridded meteorology, emissions, depositions, and concentrations data subsets can be viewed and saved using RSIG2D/RSIG3D applications.
However, there are other input data files used to run CMAQ that are not viewable in RSIG2D/3D such as:
- Sector Emissions Files
- Initial Conditions / Boundary Conditions (ICBC) Files
The CMAQ files that are currently downloadable (sector emissions) can range in size from 5 MB to 500 MB for each simulation day. Also, there are hundreds of files per product, totalling thousands of files. If all the relevant files were combined into a single compressed file, the file would be too large to download from a web site before timing out.
However, if you require such files, you can obtain them in one of two ways:
1) Download and run a custom C-Shell script titled downloader. The downloader script lists all such available data "products" and downloads sets of files from an EPA server to your computer (which should be a Linux workstation you use to run CMAQ, with several terabytes of available disk space).
2) Use the File Oriented Downloader feature of RSIG3D (on the RSIG Web tab).
