Motivation
The overall goal of this exercise is to make predictions about the global
temperature of the Earth. We will achieve this by investigating the balance
between how radiative energy is absorbed, reflected, transported, and stored
by the Earth.

Experiment 3 - Greenhouse Effect
Calculate TC (in Centigrade) with the addition of the greenhouse effect. Note
that you have to put the 'Blackbody' control in the off position in order to have
the 'A' and 'B' parameters have impact on the model. How much
Transient-State Temperature
Modify the given value for the Earth's heat capacity by making it a factor of 10
larger and then 10 smaller. Run the model and estimate the time in years for
an equlibrium temperature to be reached. Reset the heat capacity to i
The equation of state for sea water
As previously mentioned, the thermal state of sea water is determined by the
specification of three independent thermal properties. We will select as the
fundamental thermal variables the temperature T, the salinity S a
One-Dimensional Energy Balance Model
Mathematical Model
So far, we have developed a model of the earth. If desired, we could continue
to refine this model by including more complicated functions for some of the
parameters such as time and temperature depe
Numerical Model
To run this script in Matlab, type ebm_O_dim_gui and a GUI will appear (provided
you have properly set your Matlab path). Enter an initial guess for the
temperature in the upper left. Make sure that the 'Blackbody' button in the

Hot-Cold Cans
Overview
The following experiment illustrates the flow of energy into and out of a
system. We will develop a MATLAB model of this experiment and explore the
strengths and limitations of the model.

Exercises
If you have performed the experiment yourself, use an editor to make a file
called, say, cans.dat which has three columns separated by spaces: Time,
Temperature of Silver Can and Temperature of Black Can. If you do not have
such a data set, you
Theory - Greenhouse Effect
The steady-state situation given by Eqn. 1 is not fully correct because it leads
to a temperature of about -16 oC for the Earth which is well below the mean
global temperature of about 15oC. The major reason for this difference
Coriolis Force
Background
The Coriolis "force" acts to deflect horizontal motions to the right in the
Northern Hemisphere, and to the left in the Southern Hemisphere. In fact, as
we we well know, the force is in fact merely a device used to apply inertial
