heijastusprosentti
Heijastusprosentti, also known as albedo, is a measure of the reflectivity of a surface. It quantifies the proportion of incident solar radiation that is reflected back into space. The value of heijastusprosentti ranges from 0 to 1, or 0% to 100%. A surface with a heijastusprosentti of 0 absorbs all incoming radiation, while a surface with a heijastusprosentti of 1 reflects all of it.
Different surfaces have varying heijastusprosentti values. For instance, freshly fallen snow has a very high heijastusprosentti,
The heijastusprosentti plays a crucial role in Earth's energy balance and climate regulation. Surfaces with high
