(i). Net Radiation and the Planetary Energy Balance

Average Net Radiation at the Earth's Surface: January 1984-1991

 

Figure 7i-7: Average net radiation at the Earth's surface: January 1984-1991. Total net radiation is the sum of shortwave and longwave net radiation. It is dominated by the shortwave portion. Highest values occur along the subtropical oceans of the Southern Hemisphere. Lowest values occur over areas of low solar input such as the North Pole, and areas of high surface reflection such as the South Pole. Color range: blue - red - white, light green = 0 W/m2, Values: -50 to 250 W/m2. Global mean = 114 W/m2, Minimum = -60 W/m2, Maximum = 261 W/m2. (Source: NASA Surface Radiation Budget Project).
