LOTOS-EUROS

LOTOS-EUROS is a regional chemical transport model (CTM) designed for the assessment of concentrations and deposition of gaseous and particulate air pollutants. The model is used for a wide range of scientific and regulatory supporting applications. An open source version is available since October 2016.

LOTOS-EUROS in short
LOTOS-EUROS is a regional chemical transport model (CTM) that is used for a wide range of scientific and regulatory supporting applications. LOTOS-EUROS is maintained at TNO and continuously improved by developers and researchers at TNO, RIVM, KNMI. There is a close cooperation with TNO's emission experts for anthropogenic emission input of the model. Originally designed to investigate the atmospheric ozone circulation, today's LOTOS-EUROS:
  • simulates air quality and deposition over regional and sub-regional scale;
  • covers an extensive number of inert and chemically active constituents (ozone, NO2, inorganic and organic PM2.5/PM10 a.o.);
  • includes data-assimilation (satellite data and ground measurements).

and provides:

  • analyses for assessment studies;
  • (operational) air quality forecasts;
  • climate scenario’s for air quality and input to (integrative) climate models.
