Sentences with phrase «atmospheric radiative absorption»

This would require the radiative effect of clouds to change from one that increases atmospheric radiative absorption by about \ (0.5 \, \ hbox -LCB- Wm -RCB- ^ -LCB--2 -RCB- \, \ hbox -LCB- K -RCB- ^ -LCB--1 -RCB- \) to one that decreases it by \ -LRB--3.5 \, \ hbox -LCB- Wm -RCB- ^ -LCB--2 -RCB- \, \ hbox -LCB- K -RCB- ^ -LCB--1 -RCB- \).

This study seeks to explain the effects of cloud on changes in atmospheric radiative absorption that largely balance changes in global mean precipitation under climate change.

Not exact matches

The ones that are most relevant today though are those that affect atmospheric absorption and reflection of radiation, and surface impacts on either radiative or hydrologic fluxes.

The radiative absorption capability of CO2 allows atmospheric molecules to reach a higher temperature than that imparted to them by energy at the surface so they rise to a higher location than would be predicted from their weight and their individual gas constants.

Add CO2 — > increased atmospheric LW absorption — > direct radiative constraint from the E (SRF, clear) = 2OLR (clear) geometric requirement — > immediate (instantaneous) negative radiative water vapor feedback.

Instead atmospheric physics uses the fundamental equations (the radiative transfer equations) which determine absorption and emission of radiation by water vapor, CO2, methane, and other trace gases.

Would it have been so difficult to terminate the smaller atmospheric absorption arrow in the atmosphere itself and then have a separate set of arrows (both toward the surface and into space) showing the radiative energy from the atmosphere?

The reason logarithmically decreasing temperatures is atmospheric radiative gases» absorption and emission capacities, i.e., saturation levels.

CO; 2 Observations of the Infrared Radiative Properties of the Ocean «[I] t is necessary to understand the physical variables contributing to sea surface emitted and reflected radiation to space.The emissivity of the ocean surface varies with view angle and sea state, the reflection of sky radiation also depends on view angle and sea state, and the absorption of atmospheric constituents such as water vapor, aerosols, and subdivisible clouds affect transmittance.»

And, there is plenty of empirical data at every level: There is empirical data on the basic absorption lines of the various atmospheric constituents, there is a wealth of empirical data backing up the basic equations of radiative transfer that are applied in calculating the greenhouse effect in just the same way that engineers and scientists use these equations everyday in other calculations, there is empirical spectra looking both up from the surface of the earth and down from satellites.

If I were choosing a model to describe with as much quantitative fidelity as possible the greenhouse effect in the earth's atmosphere, then the model I would choose would be a state - of - the - art convective - radiative transfer code using the actual composition and empirical absorption / emission lines for the atmospheric constituents.

Relative integrated IR absorption in the atmospheric window is not the same as relative radiative efficiency
