Why don't you include Venus in the list of planets?

George, please visit my site page

I have explained there why the faster rotating planet is on average warmer

Christos, I am glad you appreciate my posts regarding your research. Third, and last one for awhile, is https://rclutz.com/2021/07/25/beware-energy-balance-cartoons/

Ron, "The table above and graph below shows that Earth’s warming factor is correctly calculated despite ignoring any effect from its thin atmosphere." Thank you!!!

Christos, I did a second post focusing on Moon and Earth

Christos, thank for this work and for linking the address at Climate Etc. I did a synopsis of your findings at my blog is: https://rclutz.com/2021/07/21/how-to-calculate-planetary-temperatures/

Ron, thank you for doing a synopsis of my findings at your blog.
We are capable now to theoretically calculate planet mean surface temperatures.
Thank you again,
Christos

Sir, did you derive this formula, or is it from a book or article on planetary science?
Christos Vournas
07.07.2020 22:05
Thank you, Craig. Yes I derived this formula.

Can anything be said about the effective surface temperature of Venus? What do you think about it?

Φ=1 for Venus' absorption budget. Jabs = (1-a)Sπr². A Planet Effective Temperature Complete Formula is for a planet-without-atmosphere. We apply it only on very thin atmosph Earth's and Titan's cases.

Thank you. I showed your page on Dr. Roy Spencer's blog and WUWT. Greetings.

The calculations of solar radiation reflection are based on the smooth spherical shape for Φ=0,47. For albedo are based on the surface features. Φ=1 is for gaseous - no surface to reflect planets.

"N rotations/day, is planet’s sidereal rotation period"
I ask for an explanation.
I understand that this is the most important point of your equation.
Christos Vournas

Thank you Ireneuzs. N rotations/day is N rotations/24 hours. The faster - the higher is its average temperature. N and pc influence the way a solar irradiated blackbody surface interact with the S .

Ireneusz, feel free to ask me anything. And thank you for asking.

Thank you for your answer. Can you explain what the calculations of solar radiation reflection are based on? Yes for a layman.

"The planet surface solar irradiation accepting factor Φ (the spherical surface’s primer geometrical quality). For Mercury, Moon, Earth and Mars without atmosphere Φ = 0,47."
Can you explain this?
Christos Vournas

The solar irradiation reflection, when integrated over a planet sunlit hemisphere is 0,53 [ ( 1- a) S ].
The fraction left for hemisphere to absorb is Φ = 1 - 0,53 = 0,47, or Jabs = Φ (1 - a ) S
