    According to the NASA heat balance diagram in link referenced above 163.3 W/m^2 made it to the surface.
    18.4 W/m^2 leave the surface through non-radiative processes, i.e. conduction and convection.
    86.4 W/m^2 leave the surface through latent processes, i.e. evaporation and condensation.
    That leaves 163.3-18.4-86.4-0.6 = 57.9 W/m^2 leaving as LWIR.

    That’s it!

    The energy balance is closed!

    Fini!!

    But what about!?
    LWIR: 398.2 total upwelling – 57.9 from balance – 0.6 absorbed = 340.3??

    An “extra” 340.3 W/m^2 have just appeared out of thin air!!!???

    So where does this 398.2 W/m^2 upwelling “extra” energy come from?

    Well, actually the 398.2 W/m^2 is a theoretical “what if” S-B heat radiation calculation for an ideal, 1.0 emissivity, Black Body with a surface temperature of 289 K or 16 C.

    The SINGLE amount of LWIR energy leaving the surface has just been calculated by TWO different methods!! and then combined to effectively double the amount!!!!

    398.2 is THEORETICAL!!!!!

    340.3 is NOT REAL!!!

    340.3 VIOLATES conservation of energy!!!!!

    And, no, it is NOT measured except by amateurs who don’t understand how IR instruments work or emissivity and assume 1.0 when it is in fact 57.9/398.2=.145.

    There is no 398.2 upwelling “extra” energy, there is no 340.3 “trapping” and “back” radiating “extra” energy, no RGHE, no GHG warming and no CAGW.
