CHAPTER 7: Introduction to the Atmosphere

(i). Net Radiation and the Planetary Energy Balance

Average Net Radiation at the Earth's Surface: July 1983-1990


Figure 7i-8: Average net radiation at the Earth's surface: July 1983-1990. 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 Northern Hemisphere. Lowest values occur over areas of low solar input such as the South Pole, and areas of high surface reflection such as the North Pole. Color range: blue - red - white, light green = 0 W/m2, Values: -50 to 250 W/m2. Global mean = 111 W/m2, Minimum = -65 W/m2, Maximum = 249 W/m2. (Source: NASA Surface Radiation Budget Project).
