Q 9. Calculate the net radiation of a snow covered surface assuming insolation is were 1,000 W/ m2, the albedo of the surface is .97, emissivity is .95, temperature is 220K, and downward Longwave radiation from the atmosphere was 350 W/m2? 10. Name the 4 factors (in hierarchical order) that are responsible for the intensity of Insolation (Incoming Solar Radiation)? 11. What is the maximum value of Earth"s Solar Constant? 12. Define the Subsolar point. What tool do we use to determine the latitude of the Subsolar Point?
