A geospatial risk analysis graphical user interface for identifying hazardous chemical emission sources.

Area of Science:

• Atmospheric Science
• Environmental Science
• Computational Science

Background:

• The Hybrid Single-Particle Lagrangian Integrated Trajectory Model (HYSPLIT) is vital for assessing atmospheric particle transport.
• Its online interface is user-friendly but limited with large or non-coincident meteorological datasets.
• Existing limitations hinder rapid hazard transport evaluation and risk analysis.

Purpose of the Study:

• To design and develop a robust, user-friendly tool for evaluating hazard transport conditions.
• To enhance risk analysis capabilities for accidental material releases.
• To overcome the limitations of the current HYSPLIT interface for large datasets.

Main Methods:

• Developed a geospatial risk analysis tool (GRAT-GUI) as a native desktop application.
• GRAT-GUI processes large meteorological datasets and supports various data formats.
• Integrated potential source distribution function (PSDF) for source identification.

Main Results:

• GRAT-GUI enables rapid processing of large meteorological datasets, even offline.
• The tool provides an intuitive interface for data integration and visualization.
• Facilitates enhanced risk analysis for hazardous chemical emissions.

Conclusions:

• GRAT-GUI offers a significant improvement over the existing HYSPLIT interface for handling large datasets.
• The tool enhances the ability to perform rapid hazard transport evaluations and risk assessments.
• GRAT-GUI provides a secure and efficient solution for atmospheric dispersion modeling and source identification.
