BDSNP Module for Improved Soil NO Emission Estimates for CMAQ Model, Conterminous USA

Published by ORNL_DAAC | National Aeronautics and Space Administration | Catalog Last Checked: August 19, 2026 at 12:18 AM | Dataset Last Updated: August 17, 2026
This model product provides: (1) the source code for the updated Berkeley-Dalhousie Soil Nitric Oxide (NO) Parameterization module (BDSNP, Version 1.0) as implemented with the Community Multi-scale Air Quality model (CMAQ, Version 5.0.2), (2) module input data from historical and new sources of maps for soil biome type, fertilizer, and arid and non-arid climates, and (3) sample CMAQ simulation outputs for three BDSNP module NO parameterizations (standard, historical, and newer inputs). The simulations use a 12-km spatial grid resolution for CMAQ modeling covering the conterminous United States for July 2011.
