Use the simple model for solar radiation under cloudless skies (p. 64) to estimate the direct, diffuse, and total solar irradiance on a horizontal surface at 45°N at local solar noon on 21 June for three values of aerosol optical thickness, 0.05, 0.20, 0.40. Assume that the optical thickness for molecular attenuation is 0.30.

Question: 5.5

## Four solar radiometers are exposed side by side. A and B have clear glass domes transmitting all wavelengths in the solar spectrum; C and D have domes that transmit 95% of the radiant energy from 700 to 3000 nm and no radiation below 700 nm. A and C receive global (total) radiation whereas B and D ...

Corrected irradiances are A = 916; B = 120; C = 46...
Question: 5.4

## Assuming a cloudless sky, estimate the downward long-wave irradiance and the atmospheric emissivity at the ground when the air temperature is 25 ºC. If the sky was covered by 50% cloud, estimate the long-wave irradiance in this case. Why are these values only climatological approximations? ...
