1. NAME AND TITLE
ATM-TOX: An Atmospheric Transport Model for Toxic Substances.
Oak Ridge National Laboratory, Oak Ridge, Tennessee.
3. CODING LANGUAGE AND COMPUTER
Fortran IV; IBM 3033.
4. NATURE OF PROBLEM SOLVED
ATM-TOX predicts concentration and deposition on the Earth's surface of airborne pollutants from
point sources (such as smokestacks), line sources (such as rows of smelters) and area sources (such as
5. METHOD OF SOLUTION
ATM-TOX provides a means of calculating the ground-level air concentrations of trace contaminants from various sources and the deposition of those contaminants on a watershed. The subsequent movement of the contaminants through the watershed by hydrologic processes can then be traced with other models.
The updated version of ATM-TOX includes a wind profile, afternoon and nocturnal mixing
heights, and first-order degradation of the airborne species. It calculates atmospheric concentration
for both wetfall and dryfall.
6. RESTRICTIONS OR LIMITATIONS

8. COMPUTER HARDWARE REQUIREMENTS
ATM-TOX is operable on the IBM 3033 computer.
9. COMPUTER SOFTWARE REQUIREMENTS
