I would imagine that since CO2 only absorbs a small portion of the spectrum that the OLR would go up if CO2 caused an increase in temperature but the spectrum that CO2 absorbs should go down but not sure if that would happen in reality. Jeff, your link is a nice fun little model but it didn't do much for me. I adjusted the CO2 and nothing changed. I don't think it can really answer the question.

Here is a simple model to help you understand what is going on with various inputs and such you can change. http://climatemodels.uchicago.edu/rrtm/ Edit: The point is that as you increase the temperature at the surface the outgoing longwave radiation also increases. This is what you asked. the temperature does not change in this model as you increase greenhouse gases. This model concerns radiative balance. You can set the temperature to whatever you wish. JimZ: You do not know how to use the model. The question concerns how outbound radiation increases as an object heats up. If you change the temperature profile you will see this. To begin with, the temperature of the Earth is not 251k. If you set the temperature of the Earth to 280k without any other input you get outbound radiation equal to a loss of 120W/m^2. If you set the temperature of the planet equal to 260k you see the outbound radiation has fallen to a loss of 32 W/m^2 You don't have to change CO2 or even include it or any other data points. Here is the models homepage: http://rtweb.aer.com/rrtm_frame.html And here is it's source code: https://github.com/jsbj/rrtm If you want to know what will occur as a result of adding certain types of greenhouse gases you can go here: http://climatemodels.uchicago.edu/modtran/

CERES satellite data shows that energy from the earths surface, mainly ends up in the atmosphere, outgoing OLR is very little effected by day/night winter/summer equator/polar, so obviously our atmosphere is acting like a big sponge soaking up the heat and radiating it out from the top of the atmosphere, so I doubt very much that measurements of OLR can tells us much, especially considering the interactions of solar radiation in the stratosphere and mesosphere.
