CHAPTER 7: Introduction to the Atmosphere

(i). Net Radiation and the Planetary Energy Balance

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


Figure 7i-5: Average net longwave radiation at the Earth's surface: January 1984-1991. Net longwave loss is a negative quantity. Highest values of longwave loss occurs where surface temperatures are high and cloud cover is minimal, such as the subtropical deserts of the Northern and Southern Hemisphere. Cold surfaces have low values of loss. Color range: white - red - blue, Values: -100 to 0 W/m2. Global mean = -48 W/m2, Minimum = -125 W/m2, Maximum = -11 W/m2.
