Lab 5: Infrared Radiation and the Greenhouse Effect

Section 2
Objectives:
In this lab, we sought to understand the role of radiation emission and radiation absorption in
regards to the earth’s atmosphere. Through experimenting, we generalized our data and
procedure to real world applications, such as satellite measurements of atmospheric and
surface temperatures. Generalizing our data to real world applications also gave us insight on
the role that temperature in the earth’s lower atmosphere depends on greenhouse gases. The
most important objective in this lab was to define and learn about the distinct roles that
radiation plays in the earth’s atmosphere. Radiation can head the earth as it is absorbed by it,
and can cool the earth as it is released (emitted) by it.
