U.K. N2O top-down emissions: Results from InTEM and RHIME 2013-2022

U.K. top-down nitrous oxide (N2O) emissions estimates for 2013-2022

Top-down emissions were derived using the InTEM (Manning et al., 2021) and RHIME (Ganesan et al., 2014) inverse models with atmospheric N2O mole fraction measurements from the U.K. DECC network (O'Doherty et al., 2020). This dataset provides monthly top-down emissions estimates for the U.K. (land-only, sea-only, land+sea components) with 68% confidence interval ranges. A priori total monthly N2O emissions created by the U.K. Emissions Model are also provided. This dataset was used in the publication "Combining top-down and bottom-up approaches to evaluate recent trends and seasonal patterns in U.K. N2O emissions" that has been submitted to JGR: Atmospheres by Saboya et al. 

Further information about the generation of this dataset and its implications can be found in Saboya et al. (2024). Please note InTEM emissions data hold a Crown Copyright.
