To map out amount and places where sunlight fell on Earth's surface during a given time period.
These maps show where and how much sunlight fell on Earth's surface during the time period indicated. Scientists call this measure solar insolation. Knowing how much of the Sun's energy reaches the surface helps scientists understand weather and climate patterns as well as patterns of plant growth around our world
