- The solar insolation at the top of the atmosphere is about 342 W/m^2. The total radiation absorbed at the surface of the Earth is 494 W/m^2. Explain how it is possible to absorb more radiation at the surface than comes in at the top of the atmosphere. (Answer should be one paragraph long)Astronomers solved this puzzle when they observed a rare transit of Venus in front of the Sun (Figure 5). What could they learn about the planet’s atmosphere from this photo?If gas expands to fill all the space available to it, explain why the Earth's atmosphere doesn't drift off into space.
- equattion : S/4 (1- a) = f*sigma*TS4 Solar Constant (W/m2) S = 1361 How sensitive is the temperature of the earth to changes in the atmospheric transmissivity (f)? The atmosphere is more transmissive (lets more radiation through) when CO2 and other greenhouse gases are lower. During the pre-industrial period, transmissivity (f) was probably around 62% (f = 0.62) and has been decreasing. Calculate how much the Earth's surface temperature would change if the transmissivity changes by ±0.01 (to 0.60 or to 0.62). ___ °C per 1% transmissivity change.On mars, the surface temperature can be 55 F What is this temperatures in Celsius scale? (Hint: T F =(9/5)T C +32)Name two factors which determine whether a planet has atmosphere or not.
- What is the difference between mass of a cubic meter of gas at sea level and mass of a cubic meter of gas in Denver. Assume a isothermal atmosphere with T=295.Numerous surface features on Venus can be seen in Earth- based images made in the ultraviolet part of the spectrum. (T/F)What is the runaway greenhouse effect, and how might it have altered the climate of Venus?
