GEOG 310 Exercise Four (F2000)
ZERO Climate Model
5 points
FIRST READ THE ZERO MODEL GUIDE, ACQUAINT YOURSELF WITH THE PROGRAM,
AND THEN DO THE PROBLEMS ON THE LAST TWO PAGES.
ZERO COMPUTER CLIMATE MODEL GUIDE
You will be working with a simple zero-dimensional computer model of the atmosphere.
It combines the effects of all atmospheric parameters to produce one result, Global Average
Temperature (GAT).
When the program is first started the following will appear on the screen (possibly after a
few odd network messages that can be ignored):

The temperature is 0.0 degrees Celsius,
and all parameters are at their standard values.

Your respo nse here should be : 0 (be sure t o hit t he ente r/re tur n key) This will initialize the
program to the current reference value of global average temperature (15.38 degrees Celsius).
The printout will be:
