- AERMOD Help Guide
A step-by-step tutorial for new AERMOD users on how to set up the model. - Background Air Quality Data
New Hampshire’s most recent monitored background values for criteria air pollutants are added to modeled impacts for evaluation against the ambient air quality standards.
Refined 2000-2004 Meteorological Data
Meteorological data (2000 to 2004) for refined (sequential) AERMOD model runs are available from the DES read-only FTP server which can be accessed at ftp://199.192.6.23/DES/ARD. Model users should refer to DES’s modeling guidance document to determine the appropriate data set to be used. The following data sets are available for download:
- Concord/Gray five-year data set (Concord met data v5.zip)
- Keene/Gray five-year data set (Keene met data v5.zip)
- Portsmouth/Gray five-year data set (Portsmouth met data v5.zip)
- Whitefield/Gray five-year data set (Whitefield met data v5.zip)
A user name and password are NOT required in order to download files. Screening modeling analyses may be done with the SCREEN3 model until the proposed AERSCREEN model (with preset meteorology) becomes available.
- Terrain Elevation Data for use with AERMAP
The AERMAP preprocessor for the AERMOD dispersion model requires terrain data in Digital Elevation Model (DEM) format. Information on DEM files and how to obtain them can be found at http://edcwww.cr.usgs.gov/products/elevation/dem.html. DES maintains a full set of DEM files for New Hampshire and will provide them to applicants at no charge as long as the files needed in the specific AERMOD analysis have been identified.
