Data needed to run AERSCREEN on the ..\Sec-3_run:   

           Emission rate = 100 g/s
            Stack height = 100 m
   Stack gas temperature = 416 K
       Exit gas velocity = 18.8 m/s
   Inside stack diameter = 4.6 m
   
   In addition you will need to determine what land use category and moisture category you should choose.
   The surface category tables, that include the surface characteristics for each category and level of moisture
   can befound in the AERMET User's Guide starting on page 3-80 (these tables have been provided).
   To determine which categories and moisture levels to choose use the file surface.sfc file from ..\Sec-3_run directory 
   see what general surface parameters were used, in each season, and then choose the category and moisture levels the 
   closes represents what was used for the Sec-3 run.  The surface file has been placed in the ..\Exercise_6 directory.
