Assuming the EarthÕs radius is 6378 km, the solar constant is 1370 W/m2 and our planetary albedo is 0.31 then
a) Determine the total power (from solar energy) entering the EarthÕs atmosphere
b) What power would be absorbed by the EarthÕs surface in the absence of an atmosphere?
c) What would the surface temperature be assuming it radiated into space all the energy it absorbed?
Anyone know what to do here? I havn't a clue what equations to use and having trouble finding them...
