The different model systems are used to make forecasts and enable us to issue warnings on shorter and longer time scales, study environmental change in the marine ecosystem, and effects of climate change. The main model systems today are EC-Earth, NEMO, PADM, RCO, SCOBI, and SCM.
EC-Earth
EC-Earth is a community global earth system model which is used to project future climate change. The oceanographic department helps with the development of the marine carbon cycle. EC-Earth takes part of the coming Coupled Model Intercomparison project 6 (CMIP6) and will be used to project future climate change and its influence on marine biogeochemistry.
NEMO
NEMO (Nucleus for European Modelling of the Ocean) is also an ocean circulation model with high resolution. It is being developed with a large European community, and has recently been set up at SMHI to model the Baltic Sea and the North Sea. The intention is that it will be used both for regional forecasting and for regional climate studies in the near future. It is already used for global climate simulations at the Rossby Centre at SMHI.
PADM
PADM (PArticle Dispersion Model) is a model to track particles in the ocean. The particles can be just passive particles, possible with a certain wind drag, representing objects or they can have properties and represent substances such as oil. PADM is the backbone of the HELCOM oil spill tracking system Seatrack Web, operated by SMHI. PADM, as well as Seatrack Web, is developed in cooperation between SMHI, FCOO, BSH and FMI.
RCO
RCO (Rossby Centre Ocean model) is also an ocean circulation model with high resolution but its intended use is mainly for studying climatic effects. It has been developed in cooperation with the Rossby Centre at SMHI.
SCOBI
SCOBI (Swedish Coastal and Ocean BIogeochemical model) is a biogeochemical model used to study how the marine system is affected by environmental and climate change related problems.
SCM
SCM (the Swedish Coastal zone Model) is a coastal multi-basins 1D model based on the PROBE (PROgram for Boundary layers in the Environment) equation solver. It is used by county administrative boards and the public, through the SMHI WaterWeb web site.
