U.S. Land Use and Sulfur Pollutant Deposition Model

Argonne National Laboratory's dataset provides land use classification on a 1/6-degree by 1/4-degree grid covering the contiguous United States. It includes a dry deposition model for computing deposition velocities of sulfur dioxide and sulfate pollutants. The data was produced by the organization SCIOPS.

Use Cases

• Model dry deposition velocities for SO2 and SO4 using the integrated deposition model and land use classification.
• Analyze spatial patterns of land cover types across the contiguous U.S. using the gridded classification data.
• Combine the land use grid with user-supplied meteorological parameters to run custom deposition simulations.
• Study potential correlations between land use categories and calculated pollutant deposition rates.

Strengths

• Spatial coverage spans the contiguous United States from 52W to 134W longitude and 24N to 54N latitude.
• Integrates a specific physical model for calculating deposition velocities of two key sulfur pollutants.

Limitations

• The spatial resolution of 1/6-degree by 1/4-degree is relatively coarse for local-scale analysis.
• The dataset's temporal coverage, update frequency, and total data volume are unspecified.
