Scattering, Absorption, and Emission of Light by Small Particles
TL;DR: In this paper, the basic theory of Electromagnetic Scattering, Absorption, and Emission was presented, and the T-matrix method and Lorenz-Mie theory were used to calculate and measure the scattering and absorption properties of small particles.
Journal ArticleDOI
A parameterization for the absorption of solar radiation in the earth's atmosphere
Andrew A. Lacis,James Hansen +1 more
TL;DR: In this article, a method is described for rapidly computing the amount of solar energy absorbed at the earth's surface and in the atmosphere as a function of altitude, which is a parametric treatment, but the form of the solution and coefficients involved are based on accurate multiple-scattering computations.
Journal ArticleDOI
Efficacy of climate forcings

Zhang +55 more
TL;DR: The authors used a global climate model to compare the effectiveness of many climate forcing agents for producing climate change and found that replacing traditional instantaneous and adjusted forcings with an easily computed alternative, Fs, yields a better predictor of climate change, i.e., its efficacies are closer to unity.
Journal ArticleDOI
Calculation of radiative fluxes from the surface to top of atmosphere based on ISCCP and other global data sets: Refinements of the radiative transfer model and the input data
TL;DR: Zhang et al. as discussed by the authors used a more advanced NASA Goddard Institute for Space Studies (GISS) radiative transfer model and improved ISCCP cloud climatology and ancillary data sets.
Journal ArticleDOI
Efficient Three-Dimensional Global Models for Climate Studies: Models I and II
James Hansen,Gary L. Russell,David Rind,Peter Stone,Andrew A. Lacis,S. Lebedeff,Reto Ruedy,L. Travis +7 more
TL;DR: In this article, a grid-point model based on numerical solution of the fundamental equations for atmospheric structure and motion is presented, which permits the explicit modeling of physical processes in the climate system and the natural treatment of interactions and feedbacks among parts of the system.
