Thermo Radiation and Temperature

  1. Jul 4, 2007 #1
    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)

    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.
