Atmospheric forcing is provided by ERA5, with lateral ocean boundaries from the CMEMS global forecast. Biogeochemical tracers are initialised and forced by a combination of world ocean atlas, GloDAP, and OC-CCI data. Output is provided as daily/monthly files on {t,u,v,w}-grid. Additional monthly output used in the construction of a nitrogen budget is also provided. For all simulations, riverine input and nitrogen deposition is input into the marine environment. The four simulations include basline scenario conditions using 2015 as a reference, and then three hindcasts including nitrogen budget under current legilation, under maximum technically feasible reduction in overall nitrogen production, and under maximum technically feasible reduction in overall nitrogen production plus a change in human diet conditions. The hindcasts are used to assess future behaviour under a given scenario. The model configuration is named SAsia. The outputs were generated under the South Asian Nitrogen Hub (SANH; NE/S009019/1) project.

Data managers quality assure submissions and assemble the metadata necessary for curation. Submissions (as received) are placed in a long-term accession and stored in triplicate across multiple sites. Appropriate data are transferred into a standard internal format with source variable names mapped to controlled vocabularies, documentation assembled, and metadata loaded into BODC databases. Access to these data is through direct request, the BODC website and through partner repositories such as SeaDataNet. Access control is attained by assigning a data policy to each set of data and this policy is used to administer access when data are requested. Discovery metadata is aligned with EU INSPIRE (through MEDIN) and SeaDataNet community standards. Data are converted to open community formats including Ocean Data View ASCII and SeaDataNet NetCDF, with data described using terms from the NERC vocabulary server. BODC submission agreements are documented on the BODC website and customer service is assured with a dedicated requests team that serve data following local regulations including General Data Protection Regulation (GDPR) 2018 and Environmental Information Regulations (EIR) 2004. true This dataset contains ocean variables from four simulations with different scenario conditions from the Southeast Asia Nitrogen Hub Biogeochemistry model. The outputs were generated from scientists at the Plymouth Marine Laboratory and the National Oceanography Centre NERC Southeast Asia Nitrogen Hub project. The data files are archived at CEDA in the format provided by the originator's and no QC was done by BODC. The data are available via a DOI.
