is the measure of how much light hits a surface and is reflected back without being absorbed.
Albedo is a universal planetary diagnostic. Astronomers use it to understand the surfaces of distant worlds. Albedo
This difference has profound consequences. If you wear a black shirt on a sunny day, you feel hot; if you wear a white shirt, you feel cooler. The planet operates the same way. The bright ice caps of the Arctic and Antarctic act as the Earth's "air conditioners," reflecting solar energy away and keeping the poles frigid. Meanwhile, the dark, absorptive surfaces of the tropics help drive evaporation and atmospheric convection, fueling the weather systems that circulate air around the globe. is the measure of how much light hits
Scientists measure albedo using instruments called pyranometers on the ground, or via satellites such as NASA’s CERES (Clouds and the Earth’s Radiant Energy System), which scans the entire planet to create global reflectivity maps. This difference has profound consequences
Definition and Significance
loop. As global temperatures rise, Arctic ice melts, replacing bright, reflective white surfaces with dark, heat-absorptive ocean water. This causes the water to warm further, melting more ice and accelerating global warming
