Global Agricultural Soil Nitrous Oxide Emissions Projections from 2010 to 2050

Annual projections of fertilizer-induced direct soil nitrous oxide emissions across global croplands and pasture at a 0.5° × 0.5° spatial resolution from 2010 to 2050. The dataset, created by Chaoqun Lu using the Dym-EF model, includes median estimates and standard deviations from 37 simulations under seven future scenarios combining climate SSPs and nitrogen regulation policies. It was last updated on May 7, 2026.

Use Cases

• Modeling future agricultural greenhouse gas emissions based on climate and policy scenarios.
• Analyzing the impact of Nitrogen Use Efficiency targets on emissions across OECD and non-OECD countries.
• Comparing soil N2O emission trajectories under high, moderate, and low ambition nitrogen regulation policies.
• Assessing the spatial distribution of projected emissions across global croplands and pasture.

Strengths

• Provides annual projections spanning 41 years (2010-2050).
• Includes median estimates and standard deviations from 37 simulations per scenario.
• Covers seven distinct future scenarios combining climate SSPs and nitrogen policy ambition levels.
• Offers a spatial resolution of 0.5° × 0.5° across global croplands and pasture.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic or temporal bias inherent to the underlying models and scenarios.
