Line‐by‐line radiative transfer computations show that the logarithmic dependence of radiative forcing on gas concentration not only applies to broadband irradiation fluxes such as in the well‐known case of the CO2 forcing, but also applies to the spectral radiance change due to both CO2 and other gases, such as H2O. The logarithmic relationship holds for monochromatic radiance requires an explanation beyond the conventional ideas based on the spectroscopic features of the gas absorption lines… 

Inhomogeneous radiative forcing of homogeneous greenhouse gases

Radiative forcing of a homogeneous greenhouse gas (HGG) can be very inhomogeneous because the forcing is dependent on other atmospheric and surface variables. In the case of doubling CO2, the monthly

Why the forcing from carbon dioxide scales as the logarithm of its concentration

The radiative forcing from carbon dioxide is approximately logarithmic in its concentration, producing about four watts per square meter of global-mean forcing for each doubling. Although these are

On the pattern of CO2 radiative forcing and poleward energy transport

A set of general circulation model experiments are conducted to analyze how the poleward energy transport (PET) is related to the spatial pattern of CO2 radiative forcing. The effects of forcing

Differential Radiative Heating Drives Tropical Atmospheric Circulation Weakening

The tropical atmospheric circulation is projected to weaken during global warming, although the mechanisms that cause the weakening remain to be elucidated. We hypothesize that the weakening is

A simple semianalytical model is presented that explains Earth’s linear OLR as an emergent property of an atmosphere whose greenhouse effect is dominated by a condensable gas and suggests that extrasolar planets with other condensable greenhouse gases could have climate dynamics similar to Earth's.

Greenhouse Effect: The Relative Contributions of Emission Height and Total Absorption

Since the 1970s, results from radiative transfer models unambiguously show that an increase in the carbon dioxide (CO2) concentration leads to an increase of the greenhouse effect. However, this

Antarctic Radiative and Temperature Responses to a Doubling of CO2

Greenhouse gases (GHGs), including carbon dioxide ( CO2 ), impact global and local outgoing longwave radiation (OLR). The Antarctic is known for its near‐surface temperature inversion, where the

Accurate integration of directional radiance shows that the conventional diffusivity-factor approximation with a constant diffusivity angle results in an overestimation of the outgoing longwave

Clouds, Circulation, and Climate Sensitivity in a Radiative‐Convective Equilibrium Channel Model

Tropical cloud and circulation changes are large sources of uncertainty in future climate change. This problem owes partly to the scale separation between large‐scale tropical dynamics ( ∼104 km) and

Understanding Rapid Adjustments to Diverse Forcing Agents

It is shown that rapid adjustments reduce the effective radiative forcing (ERF) of black carbon by half of the instantaneous forcing, but for CO2 forcing, rapid adjustments increase ERF.



Logarithmic radiative effect of water vapor and spectral kernels

Radiative kernels have become a useful tool in climate analysis. A set of spectral kernels is calculated using a moderate resolution atmospheric transmission code MODTRAN and implemented in

[1] The rate at which the outgoing longwave radiation (OLR) responds to perturbations in temperature and moisture plays a fundamental role in determining climate sensitivity. This study examines the

Using the Radiative Kernel Technique to Calculate Climate Feedbacks in NCAR's Community Atmospheric Model

Abstract Climate models differ in their responses to imposed forcings, such as increased greenhouse gas concentrations, due to different climate feedback strengths. Feedbacks in NCAR’s Community

Quantifying Climate Feedbacks Using Radiative Kernels

Abstract The extent to which the climate will change due to an external forcing depends largely on radiative feedbacks, which act to amplify or damp the surface temperature response. There are a

AbstractThis paper mainly addresses two issues that concern the longwave climate feedbacks. First, it is recognized that the radiative forcing of greenhouse gases, as measured by their impact on the
