Hemispheric albedo
Did you know?
WebPlain Language Summary The planetary albedo is the portion of solar radiation reflected by the planet back to space, and is a prime factor deciding whether the planet will warm or cool over time. An intriguing property of the albedo is that, on average, Northern or Southern Hemisphere (NH or SH) have the same albedo, called hemispheric symmetry. WebThe hemispheric symmetry of albedo and its contributing factors in satellite observations and global climate models is evaluated. The analysis is performed on the annual mean time scale, on which a bimodality in the joint distribution of albedo and cloud fraction is evident, resulting from tropical and subtropical clouds and midlatitude clouds, respectively.

Introduction 2. Data and methods a. Data b. Model output c. Methods of calculation 1) Decomposition of reflected fluxes WebEarth's albedo is observed to be symmetric about the equator on long time scales despite having an asymmetric distribution of land and aerosol sources between the northern and southern hemispheres. This is made possible by the distribution of clouds, which compensates the clear-sky albedo asymmetry almost exactly.
