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.
Gusts of the solar wind travel as fast as 1000 km/s. How many days would the solar wind take to reach Earth at this speed? (Note: The average distance to the Sun is 1.496 ✕ 108 km.)
62. Pressure of the Photosphere. The gas pressure of the photosphere
changes substantially from its upper levels to its lower levels.
Near the top of the photosphere, the temperature is about 4500 K
and there are about 1.6 x 1016 gas particles per cubic centimeter.
In the middle, the temperature is about 5800 K and there are
about 1.0 x 10" gas particles per cubic centimeter. At the bottom
of the photosphere, the temperature is about 7000 K and there
are about 1.5 × 10" gas particles per cubic centimeter. Use the
ideal gas law (Mathematical Insight 14.2) to compare the
pressures
of each of these layers; explain the reason for the trend
that you find. How do these gas pressures compare with Earth's
atmospheric pressure at sea level?

- In the graph from the class handout the inflow of energy from the sun is given as a constant 236 watts per meter squared. To get this figure we used L(1 – a) × 236 W/m², where L = 1350 W/m²is the solar constant, and a = 0.3 is the Earth's albedo (meaning that 30% of the Sun's energy is reflected back into space). The 1/4 comes from averaging the arriving solar energy over the whole Earth (the surface area of the Earth is 4 times the area of the "disk of energy" hitting the Earth.) Using these ideas estimate the inflow of energy to a planet if the solar constant is 647 watts per meter squared and the planet's albedo is 0.5. Round your answer to the near 10 watts per square meter.arrow_forwardHow does the Earth's magnetic field work, and what is its role in protecting us from the solar wind?arrow_forwardWhich of the following incidents will cause the solar constant of a planet to decrease?
