13 t of estion Distribution of Electromagnetic Radiation on the Earth's Surface The intensity of the flux for a given solar zenith angle can be determined by using (Eq 1): R = So cosine ( Z) Eq (1) Where R is the flux received in W/m, So is the solar constant which is 1,361 W/m for the Earth and Z is the zenith angle in degrees. Some versions of this equation have Ro in place of So. These are different symbols for the same thing, the solar constant. Using Eq (1), determine the flux received for a zenith angle of 12.5. Answer:

Distribution of Electromagnetic Radiation on the Earth's Surface The intensity of the flux for a given solar zenith angle can be determined by using (Eq 1): R=S0cosine( Z) Eq (1) Where R is the flux received in W/m2,S0 is the solar constant which is 1,361W/m2 for the Earth and Z is the zenith angle in degrees. Some versions of this equation have R0 in place of S0. These are different symbols for the same thing, the solar constant. Using Eq (1), determine the flux received for a zenith angle of 12.5
