ABSTRACT: On cold winter nights, air pollution can be trapped in valleys by thermal inversions. EPA’s Region 1 and ASRC Federal Vistronix created the Valley Identification Tool (https://epa.maps.arcgis.com/apps/webappviewer/index.html?id=646ebe715800410d9e5c02aa3653546d) to locate areas vulnerable to these conditions, for siting new air monitoring stations and for assisting lower-income communities with woodstove upgrades. Our Valley layer is built from a standard Digital Elevation Model, and delivered in an interactive web map that summarizes each town’s population in and out of valleys, and the locations of current air monitors as well as registered air pollution point sources. A companion web map is the Valley Profile Tool (https://epa.maps.arcgis.com/apps/Elevations/index.html?appid=d31cd5a0922c488097bca86e299d30dd) which lets users find the depth and breadth of valleys.
