MEMENTO (The MarinE MethanE and NiTrous Oxide Database)

To assess the impacts of methane and nitrous oxide emissions on radiative forcing we need an accurate synthesis of the global distribution and magnitudes of N2O and CH4 sources and sinks. MEMENTO is therefore collecting global oceanic N2O and CH4 data in an open-access database and will produce global fields of N2O/CH4 concentrations and sea-to-air fluxes that will be made publicly available via its website ( Please visit the MEMENTO website for additional information.
