APPENDIX F$_{ }$ Analysis  Type  Source  Type  Parameter  Data Source  Description  AERMAP  AERMAP is a terrain preprocessor for AERMOD. AERMAP processes  commercially available digital elevation data and creates a file suitable  for use within an AERMOD control file. Information on AERMAP is  available from the EPA at the following website:  http://www.epa.gov/ttn/scram/dispersion_related.htm#aermap.  Terrain Data  Digital Elevation  model (DEM)  Data/National  Elevation Dataset  (NED)  Elevation data needed to process AERMAP. AERMAP has been revised  to support processing of terrain elevations from the NED developed by  the U.S. Geological Survey (USGS); however, it still has the capabilities  to support terrain elevations in the original DEM format. These data sets  can be accessed at the following website, respectively:  http://ned.usgs.gov/ and http://ngdc.noaa.gov/mgg/dem/.  Background  Data  Air Data  Earliest data year is 1980. Background monitoring data collected across  the U.S. at different monitoring locations for the seven criteria pollutants  can be accessed from the EPA at the following website:  http://www.epa.gov/airdata/ad_rep_mon.html.  Traffic and  Geometry Data  Traffic Impact  Analysis of signalized  intersections  A traffic analysis of signalized intersections within study area, including  roadway geometry, traffic volumes, speeds, Highway Capacity Manual  (HCM) Synchro sheets (red/yellow/green timing/delays), level-of-service  (LOS), is the most optimal source.  Roadway  Intersection  Analysis  Mobile  Sources  Model  CAL3QHC/  CAL3QHCR  CAL3QHC is a computer based model that predicts carbon monoxide  (CO) or other inert pollutant concentrations from motor vehicles at  roadway intersections. The model includes the CALINE-3 line source  dispersion model and a traffic algorithm for estimating vehicular queue  lengths at signalized intersections. CAL3QHCR is a more refined version  based on CAL3QHC that requires local meteorological data. Models can  be accessed from the EPA at the following website:  http://www.epa.gov/ttn/scram/dispersion_prefrec.htm#cal3qhc.  Emission  MOVES or EMFAC  Requires knowledge of the computer models. MOVES is available from  109$_{ }$
