Question

the slope, aspect and albedo are three important variables upon which the radiation budget depends. Given the values for surfaces (at 34oN) in the Table below, calculate the rates of solar heating (SH) at solar noon on the equinox for the four surfaces using the following equations. Present your answers in a Table format and attach your calculations. Pay attention to your units. SH = Si(1-?) cos? where SH is solar heating in Wm-2, Si is the radiant flux density incident upon a horizontal surface (1200 Wm-2), ? is albedo and ? is the ground sun angle in degrees. The ground-sun angle is calculated using the following equation: cos ? = cos ? cos ? + sin ? sin ? cos (?sn - ?sl) where ? is the angle at which the surface is inclined (slope), Z is the zenith angle (34o), (?sn is the solar azimuth angle (south) and ?sl is the aspect (given in the Table below). Write a paragraph on what your calculations show about the effects of changing slope angle, aspect, and albedo. SURFACE: .....ROOF............. WALL.......... FIELD.............. ROCK-SLOPE SLOPE:............. 20 ...................90 ...............8 ......................30 ASPECT:........... south ............north......... south ................east ALBEDO:........... 0.20 ...............0.40........... 0.25 ..................0.20
