How to read the map:
Frost day is defined as a day with an average temperature below 0 ºC.
Stations with positive trends are in blue and stations with negative trend are in red colour. When stations are in green colour trends are not statistically significant at 25% level.
Positive values indicate cooling trend (increase in frequency) and negative values indicate a warming trend (decrease in frequency). The circle size depicts the magnitude of change in temperature per decade. Geographical coverage note: Europe
Decrease your CO2 emissions and keep your electricity bills low by making the most of natural light. Think about choosing pale-coloured walls, ceilings and floors, as well as mirrors, to reflect the daylight.
