Solar Influences Animations
Atmosphere (10.7 Mb) -
Only 1% of the TSI is absorbed by the upper atmosphere - mostly UV radiation absorbed by stratospheric ozone. About 20 - 24% heads into the lower atmosphere (troposphere) and is absorbed by waver vapor, trace gases, clouds and darker aerosols. The remaining 46 - 50% of visible light penetrates the atmosphere and is absorbed by the land and the oceans.
Complete Solar Cycle (21.4 Mb) -
The Sun's output fluctuates daily, but science concentrates on the 11-year sunspot cycle. Over the cycle the number of sunspots and associated faculae (bright regions on the Sun's surface which usually form before sunspots appear) observed range from a max 200 spots per month to as few as a dozen per month during minimum.
Global (9.25 Mb) -
What happens when solar irradiance reaches Earth? Only about 70% of the energy that reaches Earth is absorbed, while the other 30% is reflected back into space by atmosphere and aerosols, ocean/land and clouds, as seen in this animation.
Atmosphere Radiation (2.77 Mb) -
This is another animation depicting the way radiation is absorbed and reflected by the Earth.
