Trenberth-diagramm
WebNov 25, 2015 · The problem with the Trenberth diagram is that it leads to the absurd conclusion that earth is warmed twice as much by downwelling infrared radiation than by solar radiation. The reason for this absurdity is that fluxes as calculated are simply wrong. They assume thermal energy is equal at all frequencies. This is clearly not the case. WebOct 2, 2015 · The Stefan-Boltzmann law cannot be literally applied to Earth because there is no single physical radiating surface to which to apply it. Also that law, like the underlying Planck’s law, relates radiation to the temperature of the layer that emits it, so it cannot be applied to a layer that does not physically emit.

WebNov 12, 2014 · The amount of energy leaving the planet is nearly identical to the amount of solar energy being received. (Radioactive decay in the interior of the Earth makes the outgoing number slightly larger.) Without greenhouse gases, the surface heat would immediately radiate back into space, and the atmosphere would be very cold.

WebOct 3, 2024 · The global energy budget of the Earth has been calculated, based on both numerical simulations and direct observations, and its partitioning is often depicted graphically in what is known as a "Trenberth diagram" (Kiehl & Trenberth 1997; Fasullo & Trenberth 2008; Trenberth et al. 2009; Stephens et al. 2012).

If we use a more realistic emissivity of say 0.95, then the KT 97 surface radiation drops to 370.6 W/m² and his 2009 surface radiation drops to 375.8 W/m². That’s almost a 20 W/m² difference. books on the aquarian ageWeb$\begingroup$ Just making it clear (yet again unfortunately0 that the Trenberth diagram above of radiative flux in w/m^2 are NOT a HEAT or ENERGY transfer diagram but a Radiative Flux diagram. There is a big difference. People are often confused by this. books on the ave wayne mi
