The data sets are made available in machine-readable, digital format. Most of the data sets are already published. Rest of the data sets will be shared in phases as soon as it is technically ready for publishing. The Finnish Meteorological Institute also distributes the road weather observations of the Finnish Transport Agency, the radiation measurements of the Radiation and Nuclear Safety Authority and air quality observations from Finnish municipalities.
The data sets to be made available can be divided into three types: real-time observations, time series and forecasts.
This category contains continuously made observations that are used for monitoring the state or properties of the atmosphere and the Baltic Sea. Measurements are made mostly at observation stations more often than ones a day.
The category contains calculated values from the measurements and observations made at observation stations. The values calculated can be mean or extreme values of day, month or longer period.
The category contains forecast data from weather, sea, and air quality models that gives information about the future state of the athmosphere and the Baltic Sea. The output of a forecast model is usually grid like data. New forecast is commonly produced for a model more often than ones a day.
