U.K. N2O Emissions: Top-Down Estimates from InTEM and RHIME, 2013-2022

U.K. top-down nitrous oxide (N2O) emissions estimates for 2013-2022 were derived using the InTEM and RHIME inverse models with atmospheric measurements from the U.K. DECC network. The dataset provides monthly top-down emissions estimates for land-only, sea-only, and land+sea components with 68% confidence intervals, alongside a priori emissions from the U.K. Emissions Model. It was created by Eric Saboya of the University of Bristol for a publication submitted to JGR: Atmospheres.

Use Cases

• Evaluating trends in U.K. nitrous oxide emissions based on the 2013-2022 time series.
• Comparing top-down atmospheric model estimates with bottom-up inventory data based on the provided a priori emissions.
• Analyzing seasonal patterns in N2O emissions based on the monthly resolution of the data.
• Assessing uncertainty in emissions estimates based on the provided 68% confidence interval ranges for each component.

Strengths

• Data covers a 10-year period from 2013 to 2022.
• Includes monthly emissions estimates with 68% confidence intervals for three spatial components (land-only, sea-only, land+sea).
• Derived from two established atmospheric inverse models (InTEM and RHIME) using the U.K. DECC measurement network.

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.
