Calculate the vertical upward flux of reflected solar radiation with a wavelength of 12μm, assuming that the Sun with a temperature of 6000 K shines in the upper part of the sky occupying a solid angleAw = 6.8 x 10-15 sr , when the surface reflectivity isTA = 0.1 . Compare with vertical flow upwards! due to terrestrial thermal radiation corresponding to 300 K.
