Sunshine Hours

You know that sunshine impacts plant growth and production, by providing both light and heat. Sunlight also provides energy for certain chemical activities to take place in the plant, as well as promotes evapotranspiration. The amount of sunlight an area receives is often expressed in sunshine hours, which is the duration of sunshine over a given time period (days, months, or years). This map shows the yearly hours of sunshine around the world.
