NOAA Climate.gov provides timely and authoritative information about climate. The oceans influence climate by absorbing solar radiation and releasing heat needed to drive the atmospheric circulation, by releasing aerosols that influence cloud cover, by emitting most of the water that falls on land as rain, by absorbing carbon dioxide from the atmosphere and storing it for years to millions of years. Aerosols profoundly affect climate by both warming and cooling the Earth (Figure 2). Do Variations in the Solar Cycle Affect Our Climate System? The sky reflects a portion of this radiation, the rest is absorbed by the Earth and is eventually released again as thermal radiation. To accurately calculate aerosol climate forcing and If the aerosol is composed of material less prone to water uptake, such as certain organic compounds, the impact on visibility and climate forcing as relative humidity increases may not be as large. There have been many arguments as to whether or not the eleven-year sunspot cycle affects our weather and climate. Earth's climate depends on the delicate balance between incoming solar radiation, outgoing thermal radiation and the composition of Earth's atmosphere. Although solar radiation represents more than 99.9% of the energy entering Earth’s system, radiation is not the only means by which solar variability affects climate. Around 30 percent of the solar energy that strikes Earth is reflected back into space. Two different hypotheses have been proposed to test whether solar radiation can explain climate change. How Do Aerosols Influence the Earth System? In the effort to make such data easily accessible, NCEI, the Department of Energy’s National Renewable Energy Laboratory (NREL), the National Aeronautics and Space Administration, the Northeast Regional Climate Center, and several universities and companies collaborated to create the National Solar Radiation Database (NSRDB). What Role does Solar Radiation play in Determining the Earth's Climate? By David Rind — January 2009. Even small changes in these parameters can affect climate. One way in which all aerosols affect climate is through their interaction with solar radiation (sunlight). Large solar installations affect global and regional climate by taking solar radiation and distributing it in a different manner than natural processes. Hypothesis 1: UV rays, ozone, and clouds The first hypothesis relies on the fact that in both the 11 year cycle and, in the longer term, the changes in solar energy are highest at … Role Of Solar Radiation In Climate Change Date: August 11, 2009 Source: ETH Zurich Summary: A growing research field is "global dimming" and "global brightening" of solar radiation. Energy or solar radiation enters the atmosphere as sunshine. increased scattering of incoming solar radiation, a larger climate impact, and reduced visibility.
