Data Quality

Recharge estimation used the water balance approach from the annual mean 30 years of temperature and precipitation data (1981-2010) and the infiltration coefficient of different soil types. Weather data (temperature and precipitation) obtained from FMI, land use map from SYKE and supperficial deposit map of Finland at 1:20K and in some areas 1:200K from GTK. Annual mean precipitation in Finland varies between 400-750 mm with low ET and surface runoff. High recharge could be around 40-60 % of precipitation in sandy and gravelly soils and 5-15 % in clay soils.
