                    AERMOD User's Guide                    05/14/2014

This zipped file contains the User's Guide for the AMS/EPA Regulatory
Model - AERMOD (EPA-454/B-03-001, September 2004) and the current 
AERMOD User's Guide Addendum (December 2013).  The current Addendum
has been updated to reflect changes in the AERMOD model through the 
version dated 14134.  In addition, an "AERMOD Quick Reference Guide"
is included that provides a condensed summary of the AERMOD keyword
and parameter inputs, with new or revised options highlighted in red.

The 2004 User's Guide provided with this update to the AERMOD model 
includes a watermark indicating that the User's Guide is "Under 
Revision - See Addendum."  The current Addendum includes a complete
summary of the current model options in Appendix B, with detailed 
discussions of any new or updated options.  The 2004 User's Guide
should only be used for a general introduction to the AERMOD input
file structure, or for a more detailed discussion of options that
have not been added or modified since the 2004 User's Guide was
prepared.
