The USAF deputy chief of staff for air and space operations did not find any Air Force records about modeling conducted during the air campaign which would predict the effects of releasing chemical or biological warfare agents during the bombing missions. Before the Gulf War, there was very little priority given to modeling chemical and biological warfare agent dispersion. As a result, these models were relatively unsophisticated in their capabilities. Since the Gulf War, increased interest and support has resulted in major improvements in their capabilities. The Automated Nuclear, Biological, and Chemical Information System was developed to provide a realistic, real-time chemical and biological downwind hazard prediction capability.
Deposition is calculated in milligrams per square meter.
Dosage is calculated in milligrams per cubic meter of air, normally at a height of two meters above the ground.
