Earth's Energy Budget - Seasonal Cycles in Net Radiative Flux

The purpose of this lesson is to use CERES radiation data to understand seasonal variations in the pattern of net energy input to the Earth system. The students will begin to understand how Earth's tilt causes seasonal differences in incoming solar energy. They will use the Live Access Server to investigate the Earth's radiation budget and map locations using latitude and longitude coordinates. Studentw will gain an understanding of how features of the Earth system, such as clouds and deserts, modulate the reflection of energy from the Sun. The net amount of energy received by different parts of the Earth at different times of year determines the type of weather and climate these locations will experience. The net radiative flux shows the combined effect of the Sun's location and the conditions in the Earth system. The two primary components of the Earth system that affect the net radiative flux are: 1) the type of surface and 2) clouds. This lesson will allow students to explore these variations.
