FMI-ENFUSER air quality model
type: DataService
description: FMI-ENFUSER (The Finnish Meteorological Institute's ENvironmental information FUsion SERvice) produces air quality information for urban areas with high resolution. The model is based on instantaneous emission dispersion modelling (Gaussian puff) and utilizes historical air quality measurement data as well as the latest available air quality observations from the modelling area. The background concentrations of pollutants and long-range transport are obtained from the regional scale model (FMI-SILAM). Meteorological data for the dispersion model can be obtained from weather forecasting models such as HIRLAM, ECMWF or GFS depending on the modelling range.
description: ENFUSER (Environmental information Fusion Service) is an air quality model developed by the Finnish Meteorological Institute that produces high-resolution air quality information for urban areas in Finland. It uses instantaneous emission dispersion modelling (Gaussian puff), combined with historical and current air quality measurements from the modelling area. Background pollutant concentrations and long-range transport are supplied by the regional-scale FMI-SILAM model, while meteorological input comes from weather forecasting models such as HIRLAM, ECMWF, or GFS, depending on the modelling range. The service is freely accessible without authentication.”
