Atmospheric physics is the application of physics to the study of the atmosphere. Atmospheric physicists attempt to model Earth's atmosphere and the atmospheres of the other planets using fluid flow equations, chemical models, radiation balancing, and energy transfer processes in the atmosphere and underlying oceans and land.
The exosphere is the outermost layer of Earth's atmosphere (though it is so tenuous that some scientists consider it to be part of interplanetary space rather than part of the atmosphere). It extends from the thermopause (also known as the "exobase") at the top of the thermosphere to a poorly defined boundary with the solar wind and ...
The ozone layer of the Earth's atmosphere plays an important role in reducing the amount of ultraviolet (UV) radiation that reaches the surface. As DNA is readily damaged by UV light, this serves to protect life at the surface. The atmosphere also retains heat during the night, thereby reducing the daily temperature extremes.
An atmosphere (from Ancient Greek ἀτμός (atmós) ' vapour, steam ' and σφαῖρα (sphaîra) ' sphere ') [1] is a layer of gases that envelop an astronomical object, held in place by the gravity of the object. A planet retains an atmosphere when the gravity is great and the temperature of the atmosphere is low.
The "window" concept is useful to provide qualitative insight into some important features of atmospheric radiation transport. Full characterization of the absorption , emission , and scattering coefficients of the atmospheric medium is needed in order to perform a rigorous quantitative analysis (typically done with atmospheric radiative ...
Environmental sociology is the study of interactions between societies and their natural environment.The field emphasizes the social factors that influence environmental resource management and cause environmental issues, the processes by which these environmental problems are socially constructed and define as social issues, and societal responses to these problems.
Keeping our forests healthy and intact is critical to climate mitigation. Standing, living forests store billions of tons of carbon and pull carbon dioxide out of the atmosphere through ...
Air pollution is an important risk factor for various diseases, such as COPD (a common lung disease), stroke, heart disease, lung cancer and pneumonia. Indoor air pollution is also associated with cataract. [119] Air pollution has further been linked to brain disorders, such as dementia, depression, anxiety and psychosis. [120]
