Global Nitrous Oxide Budget 1980-2020
As a core component of our global greenhouse gas assessments coordinated by the Global Carbon Project (GCP), we present a global N2O budget that incorporates both natural and anthropogenic sources and sinks, and accounts for the interactions between nitrogen additions and the biochemical processes that control N2O emissions.
Nitrous oxide (N2O) is a long-lived potent greenhouse gas and stratospheric ozone-depleting substance, which has been accumulating in the atmosphere since the pre-industrial period. The mole fraction of atmospheric N2O has increased by nearly 25 % from 270 parts per billion (ppb) in 1750 to 336 ppb in 2022, with the fastest annual growth rate since 1980 of more than 1.3 ppb yr-1 in both 2020 and 2021.

Data sources and Terms of Use
The use of data is conditional on citing the original data sources. Full details on how to cite the individual data are given at the top of each spreadsheet page. In order to facilitate comparison at regional scale, the region mask is provided on a 1°x1° grid as netcdf files. For research projects, if the data are essential to the work, or if an important result or conclusion depends on the data, co-authorship may need to be considered. The Global Carbon Project – Nitrous Oxide facilitates access to data to encourage its use and promote a good understanding of the methane cycle. Respecting original data sources is key to helping secure the support of data providers to enhance, maintain and update valuable data.
