Albedo and surface temperature of the Earth

Click For Summary
SUMMARY

The discussion centers on the relationship between Earth's albedo and surface temperature, specifically addressing how an increase in albedo affects temperature calculations. The formula used is T = ((S/4σ)(1-α))^1/4, where α represents albedo. For an albedo of 0.3, the calculated average temperature is 15.45°C, while an albedo of 0.32 results in a temperature of 17.3°C. The confusion arises from the expectation that higher albedo would lead to lower temperatures, contradicting the results derived from the formula.

PREREQUISITES
  • Understanding of albedo and its impact on climate
  • Familiarity with the Stefan-Boltzmann Law
  • Basic knowledge of temperature conversion (Kelvin to Celsius)
  • Proficiency in using mathematical formulas for climate modeling
NEXT STEPS
  • Research the implications of varying albedo on climate models
  • Study the Stefan-Boltzmann Law in detail
  • Explore the effects of cloud cover on Earth's albedo
  • Learn about temperature conversion methods and their applications in climate science
USEFUL FOR

Climate scientists, environmental researchers, students studying atmospheric science, and anyone interested in the effects of albedo on global temperatures.

Homework Statement


If the Earth's average cloud cover increased, what effect would it have on the albedo temperature?

If the Earths albedo increased to 0.32, what would be the average temperature?

Ok I thought that if the albedo was higher, it would reflect more light, thus coolign would happen. But the formulas and equations are contradicting this, does anyone know why.

BTW we r using T=((S/4*sigma)(1-alpha))^1/4... for 0.3 albedo i got 15.45 deg C, which is good then 0.32 I got 17.3 deg C.

Im just really confused with this. Please can someone help

oh sorry i got the temperature conversions wrong.. K-273 not 273-K
