Unformatted text preview: emissivity? 5) For which of the absorption spectra shown below would the use of flux emissivity be most applicable, and why? E 0.1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 8 9 10 2 3 ( m) 250 K 300 K Black-body r Absorption spectra 1 adiation Absorption spectra 2 a a 6) Although we have focused mostly on absorption of long-wave radiation in the atmosphere by water vapor, a number of other gas species are also responsible for long-wave absorption (and emission). Name two of them. 7) Why isnt photolysis of O 2 a significant source of oxygen atoms (and ultimately ozone) in the troposphere? What is a significant source of oxygen atoms in the troposphere? 8) All else being equal, how would an increase in the overall gas density (i.e., concentration of M) affect the equilibrium ozone concentration? 9) What role do polar stratospheric clouds play in ozone destruction?...
