For the present situation, Ts = 288, Ta = 255, so Q = 5.670373e-8 (288^4 – 255^4) = 150 W m^-2. Now try Ts = 288, Ta = 2.7 K (the temperature of interstellar space). You get Q = 390 W m^-2.

Path length (or path) is defined as the amount of an absorber along the path. Since the amount of the absorbing gas can be expressed in different ways (see Lecture 5) the different measures of path length are used.
