What is HPAC?

HPAC software predicts the effects of hazardous material releases into the atmosphere and its collateral effects on civilian and military populations. This counterproliferation/ counterforce tool assists warfighters in destroying targets containing weapons of mass destruction and responding to hazardous agent releases. It employs integrated source terms, high resolution weather forecasts and particulate transport algorithms to rapidly model hazard areas and human collateral effects. For a more detailed description of HPAC, please read the factsheet.

How can I get HPAC?
