WebJan 14, 2009 · Globally, over the course of the year, the Earth system—land surfaces, oceans, and atmosphere—absorbs an average of about 240 watts of solar power per square meter (one watt is one joule of energy every second). The absorbed sunlight drives photosynthesis, fuels evaporation, melts snow and ice, and warms the Earth system. WebAlbedo is a quantitative measure that varies between 0 (a perfect absorber) and 1 (a perfect reflector). When we average the albedo across all of Earth's surfaces, we get the Earth's planetary albedo, which is 0.3. This means that on average, the Earth's surface reflects 30% of the incoming shortwave radiation it receives. Webentire Earth 3 (i.e., 0.30) can be quite different. Therefore, model predictions based on the average Earth albedo can be quite inaccurate. Nonetheless, the model was tested by comparing TRMM flight data with predictions based on Eq. (12) using the average Earth albedo coefficient. The following sections present more detail. razavi cmos amplifier answer key
