do you mean 10m from the surface? or what?
why do you think that relevant?
Paste from Hug's paper:
"As the transmission T = 10-3.21 is 0.6 per mille, we conclude that
the relative absorption around the peak is 1-T = 99.94% which takes
place already within a 10 m layer near ground"
Relevance?
This has always been the case. CO2 has always been present in the
atmosphere in sufficient quantity to facilitate this.
i'm not following this adequately.....
surely what matters is not where it's taking place but how
much of 'it' is happening with various gas mixes....
Note that the temperature differential between the ground and the roof
of your house is not that great. This is because the surface of the
earth cools essentially through convection and that any thermal
radiation emitted is absorbed and converted to heat (especially by
water vapour) which is added to the thermal mix.
surely what matters is how much the earth absorbs/maintains....
you've another post i haven't had time to get to yet where
you go on about churning in toffee.....
but the earth isn't seriously churning....
It's only at altitude that uninhibited thermal radiation becomes
signficant (indeed vital).
but surely what matters is not the details of how the heat is
radiated....there is always a balance reached.....
the claim is the balance is slightly higher with more gwgs
Whe people speak of global warming I presume they refer to changes in
conditions at ground level where we happen to live most of the time.
seems very reasonable....
but temperatures taken at that level must reflect the earth
temperature....
while atmospheric temperatures must/do vary considerably at different
levels of the atmosphere....those only a few feet down are very
much more stable (from year to year over present conditions)
it is those conditions i'd expect to vary by the decades as the
co2 (etc) blanket increased....and that would reflect in the
surface temperatures over time
any problems with that lot??
