Susan Solomon from the Massachusetts Institute of Technology provided a brief survey of radiative forcing changes during 2000-2014 that might have contributed to the decadal rates of global ... WebMany current applications use an “adjusted” radiative forcing in which the stratosphere is allowed to relax to thermal steady state, thus focusing on the energy imbalance in the Earth and troposphere system, which is most relevant to surface temperature change.

WebVariation in the energy from the sun is a radiative forcing external to the Earth. In our analyses of planetary energy balance and the mechanism of atmospheric warming, we … WebMay 24, 2002 · [1] The optical properties and hence the radiative forcing of atmospheric aerosols are determined, in part, by the way in which the various constituents are externally or internally mixed. The mixing state must be known to compute the effective refractive index, water activity, and size distribution of the aerosols. In this study we found that the …
Radiative forcing (or climate forcing ) is the change in energy flux in the atmosphere caused by natural or anthropogenic factors of climate change as measured by watts / meter². It is a scientific concept used to quantify and compare the external drivers of change to Earth's energy balance. System … See more Almost all of the energy that affects Earth's climate is received as radiant energy from the Sun. The planet and its atmosphere absorb and reflect some of the energy, while long-wave energy is radiated back into space. The … See more Radiative forcing can be evaluated for its dependence on different factors which are external to the climate system. Except where necessary and noted, the basic estimates which … See more Earth's global radiation balance fluctuates as the planet rotates and orbits the Sun, and as global-scale thermal anomalies arise and dissipate within the terrestrial, oceanic and atmospheric systems (e.g. ENSO). Consequently, the planet's 'instantaneous … See more Other metrics can be constructed for the same purpose as radiative forcing. For example Shine et al. say "... recent experiments indicate that for changes in absorbing aerosols and ozone, the predictive ability of radiative forcing is much worse ... we … See more Radiative forcing is defined as: "Radiative forcing is a measure of the influence a factor has in altering the balance of … See more Radiative forcing can be a useful way to compare the growing warming influence of different anthropogenic greenhouse gases over time. The table and figures below (derived by researchers at NOAA from atmospheric radiative transfer models) show changes … See more Radiative forcing can be used to estimate a subsequent change in steady-state (often denoted "equilibrium") surface temperature (ΔTs) … See more
