Sunlight is incident on a rough surface at an angle of 45 0 to the normal. Calculate
Question:
Sunlight is incident on a rough surface at an angle of 450 to the normal. Calculate the brightness temperature of the surface at wavelengths of 4 μm and 10 μm, assuming that the surface is a perfect Lambertian scatterer (i.e. one for which the diffuse albedo is 1) at both wavelengths. Ignore atmospheric propagation effects.
