MACCs
MACCS is an acronym used for several computer-based models and organizations, but it is most widely associated with tools for assessing the consequences of hazardous chemical releases. In this risk-analysis context, MACCS models simulate atmospheric dispersion, deposition, and the resulting exposure and impacts on people and property. They use input data such as chemical properties, release details (quantity, rate, duration), meteorological conditions, terrain, and population distributions to estimate downwind concentrations, affected areas, casualties, and potential economic damages. The results support emergency planning, safety analyses, and regulatory compliance for facilities handling hazardous substances.
A prominent successor in this lineage is MACCS2, which offers updated meteorological processing, expanded urban-scale capabilities,
Because MACCS is an acronym used by multiple organizations and programs across different sectors, the plural
