METR 446 Test # 3 Name: November 13, 2001 1) (25 pts) Assume the ocean is a gray-body with a wavelength-independent absorptance of 0.85. If the temperature of the ocean is 20 o C, at what solar zenith angle will the absorbed solar irradiance be equal to the emitted irradiance? You can neglect absorption or reflection within the atmosphere.

2) (30 pts) If the absorption coefficient of the gases in the atmosphere (assume all have the same average value) is 3.0x10 -5 m 2 /kg, how much total solar radiant energy is absorbed by the atmosphere every second? You can neglect reflectance, and can assume that the absorption coefficient is independent of wavelength.
