Metadata: South Asian Nitrogen Hub Regional Marine Biogeochemistry Model Under Various Scenario Conditions
Abstract:
This dataset contains outputs of four simulations from an ocean-biogeochemistry (NEMO v.4.0.4 - ERSEM) model over the South East Asia region. 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.

| Title | The title is used to provide a brief and precise description of the dataset such as 'Date', 'Originating organisation/programme', 'Location' and 'Type of survey'. All acronyms and abbreviations should be reproduced in full. | South Asian Nitrogen Hub Regional Marine Biogeochemistry Model Under Various Scenario Conditions |
| Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | British Oceanographic Data Centre record 1048_SANH_Regional_N_Models |
| File Identifier | The File Identifier is a code, preferably a GUID, that is globally unique and remains with the same metadata record even if the record is edited or transferred between portals or tools. | f8102b20a0f357e182cc954149b47c35 |
| Resource Identifier | This is the code assigned by the data owner. | EDMED7394 |
| Resource type | The resource type will likely be a dataset but could also be a series (collection of datasets with a common specification) or a service. | dataset |
| Start date | This describes the date the resource starts. This may only be the year if month and day are not known | 1993-01-01 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2020-01-01 |
| Spatial resolution | This describes the spatial resolution of the dataset or the spatial limitations of the service. | inapplicable |
| Frequency of updates | This describes the frequency with which the resource is modified or updated i.e. a monitoring programme that samples once per year has a frequency that is described as 'annually'. | asNeeded |

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | 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. |
