Average Available Solar Insolation at the Earth's Surface: July 1983-1990
| Figure 7g-3: Average available solar insolation at the Earth's surface: July 1983-1990. Highest values of available solar insolation over Greenland due to high solar input and low cloud amounts. High values also occur along the subtropics of the Northern Hemisphere. Color range: blue - red - white, Values: 0 - 350 W/m2. Global mean = 180 W/m2, Minimum = 0 W/m2, Maximum = 351 W/m2.
