Water and air sources

Model characteristics

  • Model name: MARINA-Nutrients
  • Version: Europe-1.0
  • Application: EU-28 (including the UK)
  • Scales: basins, & sub-basins, and annual
  • Period: 2020-2050

  • Pollutants:

    • For rivers: dissolved inorganic (DIN, DIP), organic (DON,DOP) nitrogen and phosphorus
    • For air: ammonia (NH3), nitrous oxide (N20),N oxides (NOx)
  • Sources: point (sewage) and diffuse (agriculture, natural areas)
  • Main inputs: agricultural activities, sewage systems, land use, hydrology
  • Main outputs: N emissions to air by agricultural sources and basin/sub-basin, river export of DIN, DON, DIP, DOP by source and basin/sub-basin
