Description. Energy leaves the . It is based on the work of many scientists over more than 100 years, with the most recent measurements from the Clouds and the Earth's Radiant Energy System . The energy a planet receives (per second) is the incident flux (energy per unit area per second) times the projected area of the planet Incident flux = (solar luminosity)/(area of sphere radius 1 AU) = L/4πD2 D=1AU the total amount of incoming solar radiation being absorbed or reflected by the surface, atmosphere, or clouds. This book provides a comprehensive presentation of Earthâs energy flows and their consequences for the climate. Very light colors have an albedo close to one (or close to 100%). The determination of the Earth's radiation budget is essential to atmospheric modeling and climate studies. For planet Earth, with a planetary solar irradiance of 1 361.0 W/m 2 (Williams, 2019), the maximum. The Earth Radiation Budget Experiment (ERBE) was designed to collect information about sunlight reaching the Earth, sunlight reflected by the Earth, and heat released by the Earth into space. Thus, the transfer of surplus energy from the lower latitudes to the deficit energy zone of the higher latitudes, maintains an overall balance over the earth's surface. Summary: In this lesson, students will explore (through labs, videos, and a simulation) how energy from the sun is absorbed, reflected and radiated back out into space as part of the Earth's energy budget. The energy radiated by the Earth toward space does not compensate the incoming radiation from the Sun leading to a small positive energy imbalance at the top of the atmosphere (0.4-1 Wm-2). This energy balance determines the climate of the Earth. EARTH'S GLOBAL ENERGY BUDGET by Ke vin e. Tr e n b e r T h, Jo h n T.
