, finally some substance . Couldn't justify spending time on this
yesterday . I assume you don't have an income stream from this
conflict either .
I don't have anything to edit PDFs which makes
contextual commenting clumsy . Your spreadsheet motivates me to try to
"read" one ( using OpenOffice ) for about the first time , and I
haven't yet figured out how to find the formulas for the graphs .
that your your derivation ? If so , I take back my
questioning of your pedigre . In any case , it's one of the cleanest I
have seen . You ought to go get the Wikipedia pages on Steran-Boltzmann
and Black-Body fixed . I like the implicit recognition that the Kirchhoff parameter is a single parameter , ε .
see no difference between us on the physics . You are wrong that
I assume a temperature of 6000k . Take another look at the table K modeling of basic black body planetary temps
. You will see I also come to a temperature of 278.7 for a solar
temperature of 5778 . An important point to note is that you see that
the essential parameter is the ratio between the values of ε for radiation to and from earth . That ratio is what I label AE
. You recognize that a default ratio is 1 which is the ratio for a
uniform flat-spectrum ( gray ) body . The overall albedo does not
matter . So you don't start with the absurd assumption , which
Martin Herzberg calls the cold earth hypothesis , that the
earth absorbs acording to its measured albedo , but radiates like a
black body . Pierrehumbert starts from this absurdity which is
where the notion that the earth would be , by my implementation :
AE : .7 1 1 ; Tcs : 5778 3 3 ; ?[ Tdif
; 0.0 ; 6000 ] / />/ 257.06
leaving 9 degrees to be explained instead of 31 .
main differences in approach is that your formula is one dimensional
implementation of the earh-sun geometry ; mine models a point
surrounded by a sphere partitioned into areas at various temperatures ,
each with its particular AE .
