Soil Nitric Oxide Emission Model for U.S. Air Quality Simulation

This dataset contains the Berkeley-Dalhousie Soil Nitric Oxide Parameterization module, its input maps, and sample outputs for the CMAQ air quality model. It provides source code, geospatial inputs for soil biome type and fertilizer application, and simulation results for the conterminous United States at a 12-km grid resolution for July 2011. The product is associated with ORNL_CLOUD and was last updated in March 2026.

Use Cases

• Comparing soil NO emissions from standard, historical, and newer input parameterizations within the CMAQ framework.
• Analyzing the spatial distribution of soil nitric oxide fluxes across the United States using the 12-km grid outputs.
• Studying the influence of fertilizer application maps and soil biome classifications on modeled nitrogen oxide emissions.
• Integrating the updated BDSNP module source code into custom CMAQ model simulations.

Strengths

• Provides three distinct model parameterizations (standard, historical, newer) for comparative analysis.
• Offers high-resolution geospatial data with a 12-km grid covering the entire conterminous United States.
• Includes both the model source code and the specific input maps (soil biome, fertilizer, climate) used for the simulations.

Limitations

• Core data is limited to a single month (July 2011), restricting analysis of seasonal or interannual variability.
• Sources conflict on the last update date, listing both November 2016 and March 2026, creating uncertainty about version currency.
• Specific column names, row counts, and dataset size are not documented across any platform.
