Wet and Dry Nitrogen Deposition for the U.S. and Western Europe, 1978-1994

United States and Western Europe data for wet and dry nitrogen-species deposition, acquired from monitoring programs. Wet deposition data spans 1978-1994, while dry deposition data covers 1989-1994, with quality assurance criteria applied for comparability. A standard geostatistical method (kriging) was used to interpolate the data onto a 0.5 x 0.5 degree resolution map.

Use Cases

• Modeling atmospheric nitrogen pollution trends based on the multi-year deposition time series.
• Creating regional geospatial maps of nitrogen deposition using the described kriging interpolation method.
• Comparing wet versus dry deposition patterns across the United States and Western Europe.
• Assessing environmental impacts of nitrogen deposition on ecosystems based on the monitored species data.

Strengths

• Data spans a significant time period: wet deposition from 1978-1994 and dry deposition from 1989-1994.
• Applied similar quality assurance criteria to ensure comparability between U.S. and European data.
• Interpolated onto a standardized 0.5 x 0.5 degree resolution geospatial grid.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
• Row count is unknown, which may limit suitability assessment.
