     Other optional inputs that may be entered on the SO pathway include specifying variable emission rate factors for sources whose emissions vary as a function of month, season, hour‑of‑day, STAR category, or season and hour‑of‑day (see Section 3.3.4 for more details).  The number of factors entered depends on the option selected, and factors may be input for  single sources or for a range of sources.  Other keywords allow the user to specify settling velocity categories, mass fractions, and reflection coefficients for sources of large particulates that experience settling and removal of the pollutant as it is dispersed and transported downwind.  This option is also explained in more detail in Section 3.

2.4.4 Specifying a Receptor Network ‑ RE Pathway

     As mentioned above, this example will illustrate the use of a single polar receptor network centered on the stack location.  Other options available on the REceptor pathway include specifying a Cartesian grid receptor network, specifying discrete receptor locations in either a polar or a Cartesian system, and specifying the location of receptors along the boundary around a particular source.  These other options are described in more detail in Section 3.4.

     For this example we will specify a polar network with receptors located at five downwind distances for every 10‑degree flow vector around the plant.  There will be a total of 180 receptors.  The RE pathway for this example will look something like this:

RE STARTING

   GRIDPOLR  POL1  STA

             POL1  ORIG  0.0  0.0

             POL1  DIST  100.  200.  300.  500.  1000.

             POL1  GDIR  36    10.   10.

             POL1  END

RE FINISHED

10
