Average Available Solar Insolation at the Earth's Surface: January 1984-1991
| Figure 7g-2: Average available solar insolation at the Earth's surface: January 1984-1991. Highest values of available solar insolation occur at the South Pole due to high solar input and little cloud cover. High values also occur along the subtropical oceans of the Southern Hemisphere. Color range: blue - red - white, Values: 0 - 350 W/m2. Global mean = 187 W/m2, Minimum = 0 W/m2, Maximum = 426 W/m2. (Source: NASA Surface Radiation Budget Project). |
