Seasonality

Model characteristics

  • Model name: MARINA-Nutrients
  • Version: China-1.1
  • Application: China
  • Scales: Yangtze sub-basins and seasonal
  • Period: 2000
  • Pollutants: dissolved inorganic (DIN)
  • Sources: point (sewage) and diffuse (agriculture, natural areas)
  • Main inputs: agricultural activities, sewage systems, land use, hydrology
  • Main outputs: river export of DIN by source and sub-basin
