  2. Artificial sunlight - Wikipedia

    en.wikipedia.org/wiki/Artificial_sunlight

    Artificial sunlight is useful in treating and preventing seasonal affective disorder (also known as winter depression, which causes depression symptoms specifically in winter), [3] and delayed sleep phase syndrome, in which the circadian rhythm (the rhythmic alternation between daylight and nighttime behavior and bodily states) is disturbed and the person falls asleep much later than he or she ...

  3. Solar simulator - Wikipedia

    en.wikipedia.org/wiki/Solar_simulator

    This category is most often used for low intensity testing, from less than 1 sun up to several suns. The total integrated irradiance for the AM1.5G spectrum is 1000.4 (280 nm to 4000 nm bandwidth) [23] which is often referred to as ‘1 sun’. Continuous light (or Continuous-Wave, CW) solar simulators may have several different lamp types ...

  4. Solar radiation modification - Wikipedia

    en.wikipedia.org/wiki/Solar_radiation_modification

    Solar radiation modification (SRM) (or solar radiation management or sunlight reflection methods [1] or solar geoengineering), is a group of large-scale approaches to limit global warming by increasing the amount of sunlight (solar radiation) that is reflected away from Earth and back to space.

  5. Stratospheric aerosol injection - Wikipedia

    en.wikipedia.org/wiki/Stratospheric_aerosol...

    Stratospheric aerosol injection (SAI) is a proposed method of solar geoengineering (or solar radiation modification) to reduce global warming. This would introduce aerosols into the stratosphere to create a cooling effect via global dimming and increased albedo, which occurs naturally from volcanic winter. [1]

  6. Should we dim the sun to help curb climate change? - AOL

    Some scientists say blocking a portion of the sun's rays could help buy humanity the time it needs to go green, but skeptics say the risks are too extreme to even consider the idea.

  7. Reflective surfaces (climate engineering) - Wikipedia

    en.wikipedia.org/wiki/Reflective_surfaces...

    By reflecting sunlight, light-colored roofs minimize the temperature rise and reduce cooling energy use and smog formation. A study by LBNL showed that, if strategies to mitigate this effect, including cool roofs, were widely adopted, the Greater Toronto metropolitan area could save more than $11 million annually on energy costs.
