Problem 56P

The planet Venus is different from the earth in several respects. First, it is only 70% as far from the sun. Second, its thick clouds reflect 77% of all incident sunlight. Finally, its atmosphere is much more opaque to infrared light.

(a) Calculate the solar constant at the location of Venus, and estimate what the average surface temperature of Venus would be if it had no atmosphere and did not reflect any sunlight.

(b) Estimate the surface temperature again, taking the reflectivity of the clouds into account.

(c) The opaqueness of Venus’s atmosphere at infrared wavelengths is roughly 70 times that of earth’s atmosphere. You can therefore model the atmosphere of Venus as 70 successive “blankets” of the type considered in the text with each blanket at a different equilibrium temperature. Use this model to estimate the surface temperature of Venus. (Hint: The temperature of the top layer is what you found in part (b). The next layer down is warmer by a factor of 21/4. The next layer down is warmer by a smaller factor. Keep working your way down until you see the pattern.)

Step-by-Step Solution:
Step 1 of 3

GEOL 207 Environmental Geology More Atmosphere Stuff!! - Albedo  reflection of light on earth. o Clouds  - Air and atmosphere in a system o Circular system (atmosphere)  Much faster than other circular systems such as plate tectonics. - CIRCULAR SYSTEMS (air)...
