This module is primarily intended for AFWA and other military forecasters. It explains the basics of how hazardous materials are dispersed in the atmosphere and how emergency responders and others model the transport and impact of the materials. The goal is to acquaint forecasters with the inputs needed for modeling and to encourage them to be proactive in providing their site-specific knowledge to improve dispersion predictions.
The module’s learning objectives are for forecasters to:
1. Describe the main factors that influence pollutant dispersion
2. Understand the basic inputs and outputs used in emergency response models
3. State or list the key uncertainties that can cause misleading dispersion model forecasts
4. Provide the meteorological inputs likely to be needed by an emergency responder
5. Use the forecasters’ local expertise to provide site-specific information that an emergency responder may not think to request
