LAB MODULE 4: GLOBAL ENERGY
Note: Please refer to the GETTING STARTED lab module to learn tips on how to set up and maneuver through the Google Earth () component of this lab.
KEY TERMS
The following is a list of important words and concepts used in this lab module:
Albedo Energy deficit Longwave radiation Conduction Energy surplus Net radiation (net flux) Convection Global energy budget Radiation Constant gases Heat Radiation budget Electromagnetic radiation Heat transfer Shortwave radiation Electromagnetic spectrum Incoming and outgoing radiation Solar constant Electromagnetic waves Insolation Solar radiation Energy Irradiance Variable gases
LAB MODULE LEARNING OBJECTIVES
After successfully completing this module, you should be able to:
œ Recognize aspects of the electromagnetic spectrum œ Distinguish between shortwave and longwave radiation and its sources œ Describe the composition of the atmosphere œ Explain how heat is transferred and measured œ Define and identify patterns of global solar insolation and albedo œ Describe the flow of solar radiation œ Describe the spatial patterns of net radiation œ Provide examples of human interactions and uses with sunlight (solar radiation)
INTRODUCTION
In this lab module you will examine some of the fundamental concepts and principles related to global energy. Topics include the electromagnetic spectrum, the composition of the atmosphere, solar radiation, the movement of radiation in the atmosphere, albedo and the global energy budget. While these topics may seem disparate, you will learn how they are inherently related. The module starts with four opening topics, or vignettes, which are found in the accompanying Google Earth file. These vignettes introduce basic concepts related to global energy. Some of the vignettes have animations, videos, or short articles that provide another perspective or visual explanation for the topic at hand. After reading each vignette and associated links, answer the following questions. Please note that some components of this lab may take a while to download or open, especially if you have a slow internet connection. Expand GLOBAL ENERGY and then expand the INTRODUCTION folder.
