Resource Title:The Earth's Radiation Budget, Part I
Description:In this exercise, students explore geographical variations in Earth's albedo, reflected solar radiation (short wave radiation), and Earth radiation (long wave radiation). Using datasets and the data viewer from the Earth Radiation Budget Experiment (ERBE), they will study data from four months of the year (winter, spring, summer, and fall) to discover variations in albedo due to geographic location (longitude and/or latutude), and due to seasonal variation. They will also examine data for incoming solar radiation to see seasonal variations from winter to summer, and examine the clear-sky longwave radiation dataset to see seasonal variations in Earth radiation. In three hands-on experiments, they will use a globe and a photocell to demonstrate the effect of Earth's spherical shape on change in solar radiation with latitude, study albedo by testing the reflectivity of paper of various colors and textures, and examine radiative energy flux by measuring the amount of light received from a lamp placed at increasing distances from a photometer.
