Seasonality in pollution

Model characteristics

  • Model name: MARINA-Multi
  • Version: Global-5.0
  • Application: Global
  • Scales: sub-basins and seasonal
  • Period: 2010-2100
  • Pollutants: dissolved inorganic (DIN, DON) and organic (DON, DOP) nitrogen (N) and phosphorus (P), triclosan, microplastics, macroplastics, and diclofenac
  • Sources: diffuse sources (agricultural runoff) and point sources (sewage systems, open defecation, direct discharges of manure)
  • Main inputs: livestock numbers, manure excretion rates, land use, crop production, sewage connections, removal efficiencies, water consumption, hydrology, temperature
  • Main outputs: seasonal river export of DIN, DON, DIP, DOP, triclosan, microplastics, macroplastics and diclofenac by source and sub-basin
