EnviroAtlas - 2002 Edge-of-Field Simulated Nitrogen, Phosphorus and Water Quantity Loss by 12-digit HUC for the Conterminous United States

Metadata Updated: August 30, 2023

This EnviroAtlas dataset contains annual (2002) simulated estimations of edge-of-field agricultural nitrogen (N) and phosphorus (P) lost in surface runoff, subsurface flow (tile and non-tile) and percolate, N and P attached to eroding soil (sediment loss) and associated surface, subsurface and vertical water flow and surface soil erosion. The dataset was generated using Weather Research Forecast (WRF) modeled weather, Community Multi-Scale Air Quality (CMAQ) model deposition and the Environmental Policy Integrated Climate (EPIC) model as implemented under the Fertilizer Emission Scenario Tool for CMAQ (FEST-C), all run for 12-km rectangular grids across the continental US. This dataset was produced by the US EPA to support research and online mapping activities related to EnviroAtlas. EnviroAtlas (https://www.epa.gov/enviroatlas) allows the user to interact with a web-based, easy-to-use, mapping application to view and analyze multiple ecosystem services for the contiguous United States. The dataset is available as downloadable data (https://edg.epa.gov/data/Public/ORD/EnviroAtlas) or as an EnviroAtlas map service. Additional descriptive information about each attribute in this dataset can be found in its associated EnviroAtlas Fact Sheet (https://www.epa.gov/enviroatlas/enviroatlas-fact-sheets).
