On Aerosol Direct Shortwave Forcing and the Henyey–Greenstein Phase Function
Publisher: American Meteorological Society
Abstract: This technical note extends previous Mie calculations to show that there are complex relationships between the asymmetry parameter g and the upscatter fractions for monodirectional incident radiation ?(?0). Except for ...
GCM Estimate of the Indirect Aerosol Forcing Using Satellite-Retrieved Cloud Droplet Effective Radii
Publisher: American Meteorological Society
Abstract: In a recent paper, Han et al. analyzed satellite data radiances to retrieve cloud droplet effective radii and reported significant interhemispheric differences for both maritime and continental clouds. The mean cloud droplet ...
Comment on “Rethinking the Lower Bound on Aerosol Radiative Forcing”
Publisher: American Meteorological Society
Abstract: AbstractIn an influential and interesting study, Stevens (2015) suggested that the global and also Northern Hemispheric warming during the early industrial period implies that the effective radiative forcing by anthropogenic ...
Sulfate Aerosol Indirect Effect and CO2 Greenhouse Forcing: EquilibriumResponse of the LMD GCM and Associated Cloud Feedbacks
Publisher: American Meteorological Society
Abstract: The climate sensitivity to various forcings, and in particular to changes in CO2 and sulfate aerosol concentrations, imposed separately or in a combined manner, is studied with an atmospheric general circulation model ...
Why Does Aerosol Forcing Control Historical Global-Mean Surface Temperature Change in CMIP5 Models?
Publisher: American Meteorological Society
Abstract: inear regression is used to examine the relationship between simulated changes in historical global-mean surface temperature (GMST) and global-mean aerosol effective radiative forcing (ERF) in 14 climate models from CMIP5. ...
Adjustments in the Forcing-Feedback Framework for Understanding Climate Change
Publisher: American Meteorological Society
Abstract: he traditional forcing?feedback framework has provided an indispensable basis for discussing global climate changes. However, as analysis of model behavior has become more detailed, shortcomings and ambiguities in the ...

Declining Aerosols in CMIP5 Projections: Effects on Atmospheric Temperature Structure and Midlatitude Jets
Publisher: American Meteorological Society
Abstract: he effects of declining anthropogenic aerosols in representative concentration pathway 4.5 (RCP4.5) are assessed in four models from phase 5 the Coupled Model Intercomparison Project (CMIP5), with a focus on annual, ...
An “A-Train” Strategy for Quantifying Direct Climate Forcing by Anthropogenic Aerosols
Publisher: American Meteorological Society
Abstract: This document outlines a practical strategy for achieving an observationally based quantification of direct climate forcing by anthropogenic aerosols. The strategy involves a four-step program for shifting the current ...
