WHAT IS ALBEDO?
Albedo is the reflected solar radiation emitted by the any surface or body. As we know sun is the main source of electromagnetic radiation, and every object on earth reflects these radiations back to the environment. It is another name for reflectivity. High albedo surface reflects more radiation and absorbs the remaining radiation and Low albedo means, it absorbs max radiation and reflects a very small amount thus increasing the temperature of the surrounding.
How are Public Health and climate related to Albedo?
In urban areas the albedo of the surface is very low, the concrete buildings and roads absorb most of the radiation, and reflect a very less amount, thus increasing the temperature of the local area. Increase in Temperature affects health of people in adverse manner. Flora and Fauna of the area start reacting to the extreme change in the climate.
