Description:

This presentation provides an introduction for the live demo and explains the purpose of C-LINE and its key features. C-LINE is a web-based model designed to inform the community user of local air quality impacts due to mobile-sources in their region of interest using a simplified modeling approach. It is designed for examining what-if scenarios of changes in emissions, such as those due to changes in traffic volume, fleet mix, or vehicle speed. The model is not intended to be used for any regulatory, enforcement or permitting decisions.

Purpose/Objective:

The National Exposure Research Laboratory (NERL) Computational Exposure Division (CED) develops and evaluates data, decision-support tools, and models to be applied to media-specific or receptor-specific problem areas. CED uses modeling-based approaches to characterize exposures, evaluate fate and transport, and support environmental diagnostics/forensics with input from multiple data sources. It also develops media- and receptor-specific models, process models, and decision support tools for use both within and outside of EPA.
