Sentences with phrase «radiative effect»
The phrase "radiative effect" refers to the influence or impact of radiation. It describes the way radiation, such as heat or light, affects a system or its environment. It could imply changes in temperature, energy absorption, or other reactions caused by the presence or transfer of radiation. Full definition

The direct and indirect radiative effects of aerosols suspended in the atmosphere above clouds (ACA) are a highly uncertain component of both regional and global climate.
On the other hand, in addition to its direct radiative impact, methane has a large, indirect radiative effect because it contributes to ozone formation.
But in the last 20 years, models have suggested that radiative effects play a key role.
Some studies have found that the dominant radiative effect of clouds is cooling.
The global warming potential is an attempt to provide a simple measure of the relative radiative effects of the emissions of various greenhouse gases.
Effectively, methane increases its own atmospheric lifetime and therefore its overall radiative effect.
In any case, the calculation of the total radiative effect needs to include both the direct and indirect forcing.
The direct radiative effects of aerosols can be divided in reflection and absorption.
Some gases have indirect radiative effects (whether or not they are greenhouse gases themselves).
Fig. 3: Short - wave cloud radiative effect.
The third figure shows the model - simulated change in solar cloud radiative effect with climate warming, with positive changes implying that clouds have an amplifying effect.
In our simulations, the global - mean aerosol direct radiative effect changes by 0.06 W / m2 during 1996 to 2010, while the effective radiative forcing (ERF) is 0.42 W / m2.
However, the models also suggest that, as we go forward in time, the relative importance of increasing radiative effects, compared with atmosphere and ocean dynamic effects, is likely to increase.
Raypierre, according to Wang and Key in Science (unfortunately under subscription): «Are these changes due to large - scale advective processes rather than to local radiative effects?
A 1 % decrease in cloud cover has a slightly higher radiative effect as all the observed loss of Arctic sea ice to date has had.
(Ramanathan and Inamdar 1989) So a 1 % decrease in cloud cover has a slightly higher radiative effect as all the observed loss of Arctic sea ice to date has had.
When partnered with cloud remote sensing observations the radiation measurements and retrievals allow the characterization of cloud and aerosol radiative effects at the surface, which is essential in order to quantify the amount of radiative energy available at the surface to interact with heating the air, evaporating water, and interacting with clouds and greenhouse gasses in the atmosphere.
absorbing aerosols, which lead to a positive radiative forcing of the troposphere with little net radiative effect at the top of the atmosphere;
None of that compromises the kind of stuff that's needed to accurately calculate the GHG radiative effect in Earthlike conditions.]
