Homework Help: Atmosphere layers

  1. Jan 24, 2010 #1

    1. The problem statement, all variables and given/known data

    Consider a one layer atmosphere for the planet Venus. 19% of incoming solar radiation is absorbed by the atmosphere. 99% of the outgoing radiation is absorbed by the atmosphere. The incoming radiation, E, as measured by satellite is 615 Wm-2.

    1) Derive two equations, one for the top of the atmosphere and the other for the Venusian surface in terms of x, y and E. Solve for the surface and atmospheric temperatures.



    2. Relevant equations
    None we need to create the equations but i do not know where to start.


    3. The attempt at a solution
    Please help! i have no clue where to start

    If 19% of the incoming radiation from the sun is absorbed, what happens to the other 81%? If the whole atmosphere is in thermal equilibrium, what must the lower atmosphere radiate back out?
