Research Topic Description, including Problem Statement:

From an atmospheric modeling perspective, urban environments are exceedingly complex. The movement of materials is driven by multiple non-linear processes with nearly infinite dimensionality. Current models are forced to balance using high order approximations to reduce computing time with loss of accuracy and reproducibility. When all of this is combined with the need for rapid responses to potentially hazardous chemical plumes (chemical attacks, industrial toxins, etc.), the current models fall far short of what is needed.

This solicitation seeks to find an approach for characterizing the key variables and information needed to accurately model plumes in urban environments.

Accurate and rapid modeling of chemical plumes is critical for providing local, national, and global leaders with the information necessary to protect civilians and military personnel from hazardous areas.

Example Approaches:

The focus of this effort is on reducing computational time without sacrificing accuracy of computational models. Approaches can be compared to available experimental data for validation. Relevant data and techniques include computer vision, AI/ML, weather modeling/prediction, traditional plume modeling variables as well as new information streams.

Relevance to the Intelligence Community (IC):

Develop/enhance capabilities to detect and identify chemical agents, and associated delivery systems. Develop/enhance capabilities to rapidly characterize the release of chemical, biological, radiological, nuclear, and/or related hazardous materials.
