The Finnish Meteorological Institute share the following data

The data sets to be made available can be divided into three types: real-time observations, time series and forecasts. List of all Open data (in Finnish).

Real-time observations

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.

• Wave and other observations from buoys

• Sea level observations

• Weather observations

• Sun radiation observations

• Lightning strikes

• Radar images

• Air quality observations

• Upper-air sounding observations: ascending and descending

• METAR weather reports

Time series of observations

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.

• Station specific daily and monthly values

• Values of 30-year normal periods

Forecast and forecast models

The category contains forecast data from weather, sea, and air quality models that gives information about the future state of the atmosphere 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. 

• Weather forecast models HARMONIE and ECMWF

• Meteorologist's weather forecast

• Air quality forecast models SILAM and FMI-ENFUSER

• Sea models: waves, currents (NEMO), sea surface temperature and sea ice (HELMI)

• Sea level model for predefined points (NEMO)

• Climate change forecasts for the 30-year periods 2010 - 2039, 2040 - 2069 and 2070 - 2099.
