Thermo Radiation and Temperature

Click For Summary
SUMMARY

The forum discussion centers on the hypothetical scenario of a thin spherical shield placed above Earth's atmosphere that absorbs all solar radiation. Participants clarify that the shield's effect on Earth's average temperature, initially at 300K, depends on whether it blocks incoming solar radiation or prevents outgoing thermal radiation. The discussion emphasizes the importance of the shield's temperature in determining the resultant average temperature of the Earth's surface.

PREREQUISITES
  • Understanding of thermodynamics and radiation principles
  • Knowledge of Earth's energy balance and temperature regulation
  • Familiarity with concepts of thermal equilibrium
  • Basic physics of solar radiation and its interaction with materials
NEXT STEPS
  • Research the principles of thermal radiation and emissivity
  • Explore the concept of Earth's energy balance and climate models
  • Study the effects of solar radiation on planetary temperatures
  • Investigate materials that could theoretically be used for radiation shielding
USEFUL FOR

Hi
Here is the question.
Suppose someone build a thin spherical shield just above the Earth's atmosphere, and it would absorb all the radiation passing through from the sun. What would the average temperature of the Earth's surface be? (Assuming the avg temperature of the Earth is initially 300K)
 
Science news on Phys.org
Do you mean the shield would block all the radiation coming from the sun or stop any radiation leaving the the Earth?
It would also depend on what temperature the shield was at.
