Valleys - US EPA Regions 1, 2, 3, 9 (2022) and 10 (2024)
Valleys, featured in the Valley Identification Tool, are locations that have a lower elevation than surrounding areas. EPA Region 1 GIS Center applied ArcGIS' Focal Statistics tool to the USGS 30-meter NED DEM to find places where elevations are significantly less than average. We then quantified population and wood fuel usage within Census County Subdivisions to find locations which may be vulnerable to wood smoke pollution during winter thermal inversions.
Created by US EPA Region 1 GIS Center; and implemented in EPA Regions 2, 3 and 9 in 2022 and Region 10 in 2024 by regional GIS staff, US EPA Office of Mission Support (OMS).
