Abstract
This dataset contains outputs of a simulation 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. Outputs are provided as daily and monthly files on a {t,u,v,w}-grid. Additional monthly output used in the construction of a nitrogen budget is also provided. For this simulation, riverine input and nitrogen deposition is input into the marine environment under baseline conditions using 2015 as a reference. The model configuration is named SAsia. The outputs were generated under the South Asian Nitrogen Hub (SANH; NE/S009019/1) project.
