AREAS: A COMPUTER CODE FOR ESTIMATING AIR POLLUTANT CONCENTRATIONS FROM DISPERSED SOURCES

The AREAS area-source computer code, written in FORTRAN IV, is described and listed. This code, which runs in less than 7 seconds on the IBM 360/91 computer, estimates annual-average concentrations of an air pollutant at ground level in each of 400 grid squares in a 20 by 20 area reference grid. AREAS can be used for multiple, dispersed sources located in each of the 400 grid squares by treating them as area sources. Required input includes 20 by 20 arrays of annual-average point-source chi/Q values generated by use of a point-source model or computer code for specific grid sizes relative to the size of the area reference grid. AREAS can be applied to any size area for which a uniform meteorology can be assumed. It has been applied to dispersed emissions of fossil fuel combustion products and automobile emissions in Roane County, Tennessee, and to the atmospheric dispersion of radionuclides emitted from the tailings piles of uranium mills.
