Global Nitrous oxide budget (GNB)
The LOAC is a key component of the GNB. Our team has synthesized estimates of N2O emissions from inland waters (IW: streams, rivers, lakes, reservoirs), estuaries and coastal vegetated ecosystems (ECV), and the continental shelves (CS) using a consistent spatial framework. In the context of the upcoming GNB (Tian et al., 2024) our assessment has been gridded, and where relevant, decomposed into a natural and anthropogenic component flux. The contribution of the shelves as a hotspot of natural N2O emissions is an important finding of the upcoming budget.

Regional budget
Present-day water-air N2O emissions in inland waters (IW: streams, rivers, lakes, reservoirs etc…), estuaries and coastal vegetated ecosystems (ECV), and continental shelves (CS) have been quantified and regionalized in the context of RECCAP2, using a fully consistent framework allowing their integration into both land and ocean budgets. Climatological means are provided for ECV and CS while trends are also resolved for IWs.
