Students collect and analyze temperature data to explore what governs how much energy is reflected. 

 Air, Water, Land, & Life: A Global Perspective

Students will analyze a graph showing the amounts of peak energy received at local noon each day over the year changes with different latitudes. 

Dr. Norman Loeb, an atmospheric scientist at NASA’s Langley Research Center in Hampton, Virginia, is the principal investigator for an experiment called the Clouds and the Earth’s Radiant Energy System (CERES). CERES instruments measure how much of the sun’s energy is reflected back to space and how much thermal energy is emitted by Earth to space.
