Question

Determine the emission temperature

of the planet Venus. You may assume

the following: the mean radius of

Venus’ orbit is 0.72 times that of

the Earth’s orbit; the solar flux So

decreases as the square of the distance

from the Sun and has a value of

1367Wm?2 at the mean Earth orbit;

Venus’ planetary albedo = 0.77.

Answer #1

Do not solve the following question
numerically unless specifically asked to do so. The flux from the
Sun’s surface is given by L(sun)= 4πR(sun)^2 σT(sun)^4 , where
T(sun) is the temperature on the Sun’s surface.
(a) What Is the incident luminosity
from the Sun seen on Earth’s surface?
(b) Only a part of the luminosity
incident on Earth’s surface is reflected back. The fraction of
radiation reflected from Earth’s surface, or albedo, is given by A.
The other part is...

You are embedded in the Kepler program in which planetary
systems are being detected around other stars. You detect a
possible planet in orbit around a star whose peak wavelength of
radiation is 0.38 microns, which is considerably shorter than that
of our Sun. Calculate the “goldilocks distance” for this system,
the orbital distance from this star at which you would expect a
planet to have a surface temperature of 0°C. (Assume the planet has
an albedo of 0.3, and...

Problem 2
a) What is the radiant power of the sun?
b) What is the radiant power at the surface of the earth?
c) Calculation of the solar constant
d) How much energy does the earth absorb?
e) Using the equilibrium condition to calculate the earth’s
temperature (W/O atmosphere) ? (Give a brief comment regarding your
findings)
f) Using the equilibrium condition to calculate the earth’s real
temperature (W/ atmosphere)? (Give a brief comment regarding your
findings)
Problem 3 (Very...

This is from Principles of Planetary Climate, Problem 1.13
The thick CO2 atmosphere of Venus is nearly opaque in the
infrared, so observations of Venus in the infrared spectrum provide
no direct information about the temperature of the ground. However,
the atmosphere is nearly transparent to microwave radiation, so the
microwave emission of the planet can be used to infer its surface
temperature. Indeed, this is how it was inferred in the 1960s that
the surface of the planet was...

Explore the dependence of sunlight on earth-sun distance. The
solar constant, S_0 is the solar radiation at zero zenith angle at
the mean earth-sun distance, R_m. As we learned in class the
intensity of solar radiation decreases with the square of the
distance. Use matlab to devise a function that calculates the daily
averaged solar radiation as it depends on earth-sun distance
(ignore seasonal changes in the sun's angle) through the course of
one year. Use for the eccentricity the...
