A THOUGHT EXPERIMENT: let's compare Te.moon =270K with Tsat.io =110K

A THOUGHT EXPERIMENT

========

PAGE IS IN PROGRESS

*********

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!
