Marine cloud brightening proposes to generate a similar effect using benign material (e.g. sea salt) delivered to clouds that are most susceptible to these effects (marine stratocumulus). Most clouds are quite reflective, redirecting incoming solar radiation back into space. Increasing clouds' albedo would increase the portion of incoming solar ...
Post-eruptive loops in the wake of a solar flare, image taken by the TRACE satellite (photo by NASA). In solar physics, a solar particle event (SPE), also known as a solar energetic particle event or solar radiation storm, [a] [1] is a solar phenomenon which occurs when particles emitted by the Sun, mostly protons, become accelerated either in the Sun's atmosphere during a solar flare or in ...
Sea salt aerosols can alter the Earth radiation budget through directly scattering solar radiation (direct effect), and indirectly changing the cloud albedo by serving as CCN (indirect effect). Different models give different predictions of annual mean radiative forcing induced by sea salt direct effect, but most of the previous studies give a ...
The ocean's surface has unique chemical and physical properties that may concentrate species specifically adapted to these conditions. For example, bacterioneuston living in the sea surface microlayer are often brightly coloured, [30] possibly as protection against solar radiation.
Managing solar radiation using aerosols or cloud cover would involve changing the ratio between direct and indirect solar radiation. This would affect plant life [ 65 ] and solar energy . [ 66 ] Visible light, useful for photosynthesis, is reduced proportionally more than is the infrared portion of the solar spectrum due to the mechanism of Mie ...
An unusually strong solar storm hitting Earth produced stunning displays of color in the skies across the Northern Hemisphere early Saturday, with no immediate reports of disruptions to power and ...
Variations in the ultraviolet component. The UV component varies by more than the total, so if UV were for some (as yet unknown) reason to have a disproportionate effect, this might explain a larger solar signal. Effects mediated by changes in galactic cosmic rays (which are affected by the solar wind) such as changes in cloud cover.
A severe geomagnetic storm could disrupt communications and bring northern lights to parts of California, according to a warning from the National Oceanic and Atmospheric Administration.
