Quantifying Snow Albedo Radiative Forcing and Its Feedback during 2003-2016
Snow albedo feedback is one of the most crucial feedback processes that control equilibrium climate sensitivity, which is a central parameter for better prediction of future climate change. However, persistent large discrepancies and uncertainties are found in snow albedo feedback estimations. Remotely sensed snow cover products, atmospheric reanalysis data and radiative kernel data are used in...
متن کاملRadiative forcing and albedo feedback from the Northern Hemisphere cryosphere between 1979 and 2008
The extent of snow cover1 and sea ice2 in the Northern Hemisphere has declined since 1979, coincident with hemispheric warming and indicative of a positive feedback of surface reflectivity on climate. This albedo feedback of snow on land has been quantified from observations at seasonal timescales3–6, and century-scale feedback has been assessed using climate models7–10. However, the total impa...

متن کاملWhat Controls the Strength of Snow-Albedo Feedback?
The strength of snow-albedo feedback (SAF) in transient climate change simulations of the Fourth Assessment of the Intergovernmental Panel on Climate Change is generally determined by the surfacealbedo decrease associated with a loss of snow cover rather than the reduction in snow albedo due to snow metamorphosis in a warming climate. The large intermodel spread in SAF strength is likewise attr...
متن کاملAssessing Snow Albedo Feedback in Simulated Climate Change
We isolate and quantify the two factors controlling Northern Hemisphere springtime snow albedo feedback in transient climate change based on scenario runs of 17 climate models used in the IPCC 4th Assessment. The first factor is the dependence of planetary albedo on surface albedo, representing the atmosphere’s attenuation effect on surface albedo anomalies. It is potentially a major source of ...
