We do the planets and moons surface temperatures comparison.
The presence of atmosphere doesn't warm Earth's surface.
It is the other reasons, not the presence of atmosphere, that make Earth warmer than the Moon by +68°C.
A THOUGHT EXPERIMENT
========
*********
Let's perform a thought experiment, let's suggest Moon is a heavy cratered planet, and therefore, Moon has Φ = 1;
It can be shown, Moon's (thought experiment) mean surface temperature would be then very much close to the Moon's effective temperature
Te.moon = 270K
*****
The comparison coefficient is:
[ (1-a) (1/R²) (N*cp)¹∕ ⁴ ]¹∕ ⁴
***
Moon:
R = 1
a = 0,11
N = 0,0339 rotations/day
cp = 0,19 cal /gr.oC
Moon's comparison coefficient calculation:
[ (1-a) (1/R²) (N*cp)¹∕ ⁴ ]¹∕ ⁴
[ (1-0,11) (1²) (0,0339*0,19)¹∕ ⁴ ]¹∕ ⁴ =
[ (0,89) (1) (0,00641)¹∕ ⁴ ]¹∕ ⁴ =
[ (0,89) (1) (0,2833) ]¹∕ ⁴ =
(0,25213)¹∕ ⁴ = 0,70861
*******
Io:
R = 5,20
1/R² = 1/5,2044² = 0,0369
a = 0,63
N = 0,5559 rotations/day
cp = 0,145 cal /gr.oC
Io's satellite measured mean surface temperature is
Tsat.io = 110K
Comparison coefficient calculation:
[ (1-a) (1/R²) (N*cp)¹∕ ⁴ ]¹∕ ⁴
[ (1-0,63) (1/5,2044²) (0,5559*0,145)¹∕ ⁴ ]¹∕ ⁴ =
[ (0,37) (0,0369) (0,08060)¹∕ ⁴ ]¹∕ ⁴ =
[ (0,37) (0,0369) (0,53283) ]¹∕ ⁴ =
(0,0072747)¹∕ ⁴ = 0,29205
******
Let's proceed,
let's compare Te.moon =270K with Tsat.io =110K:
Te.moon /Tsat.io = 270K /110K = 2,4545
*******
Let's compare the Moon's and Io's comparison coefficients:
Coeff.moon /Coeff.io = 0,70861 /0,29205 = 2,4263
*******
2,4545 /2,4263 = 1,0116
or only 1,16% difference !!!
*******
Conclusion:
Everything is all right.
It is a demonstration of the Planet Surface Rotational Warming Phenomenon!
