Combining these new images and photometry with ancilliary data from the literature, we undertook simultaneous multi-wavelength modelling of the discs» radial profiles and spectral energy distributions using three different methodologies: single annulus, modified black body, and a radiative transfer code.

With funding from the U.S. Department of Energy, AER has developed the highly accurate and efficient radiative transfer code RRTMG for application to global models.

3) Under the assumption of radiative equilibrium, it can be shown that the surface temperature of a planet would slightly and non linearily increase with the concentration of IR active gases (primarily H2O) if and only if radiation was the only mean for energy transfer.

Studies have shown that these radiative transfer models match up with the observed increase in energy reaching the Earth's surface with very good accuracy (Puckrin 2004).

As you say, convection uses up a lot of energy too and also counters the idea of radiative heat transfer as a big ticket item because «hot» CO2 molecules only remain so for a brief fraction of a second before they collide with N2 or O2 to warm that localised parcel of air; which then rises to attain equilibrium T somewhere higher and at a COLDER temp so no rad Transf!!!

A: A number of issues associated with climate change are fundamental physics topics, including the connection between greenhouse gas increases and warming, radiative transfer, spectroscopy, thermodynamics, and energy balance.

The problem with this particular fantasy kim is that the physics of radiative transfer mean that increasing the fraction of atmospheric CO2 will cause energy to accumulate in the climate system (mainly the global ocean)-- exactly as observed.

Therefore, any absorption band within spitting distance of 57 microns should be taken into account with respect to radiative - transfer effects on the energy - transport question; anything very far away need not be.

I thought that in the adiabatic case (in order to mirror the atmosphere) there is nil radiative or conductive heat flow.That is the standard atmosphere model where conduction is very small compared with other energy transfers.

Web said,» There only way that the earth can exchange energy with the external system is through radiative energy transfer.»

La Nina certainly cools the atmosphere with energy transferred between ocean and atmosphere — but different lines of evidence suggest that cloud radiative effects dominate with both oceans and atmosphere cooling.

Well, as you can see from this thread, you might be OK with radiative transfer code, but plenty of others are confused about radiation and the conservation of energy, in general.

The reason this warms the surface is most easily understood by starting with a simplified model of a purely radiative greenhouse effect that ignores energy transfer in the atmosphere by convection (sensible heat transport) and by the evaporation and condensation of water vapor (latent heat transport).
