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.

It is a demonstration of the Planet Surface Rotational Warming Phenomenon!
All the data below are satellite measurements. All the data below are observations.
Planet….Earth….Europa
Tsat.mean 288 K….102 K
R…...........1 AU…5,2044 AU
1/R²………1…….0,0369
N………....1……1/3,5512 rot./day
a…………..0,306……0,63
(1-a)………0,694……0,37
coeff...0,9127...0,3158
Comparison coefficient calculation
[ (1-a) (1/R²) (N)¹∕ ⁴ ]¹∕ ⁴
Earth:
Tsat.mean = 288 K
[ (1-a)*(1/R²)*(N)¹∕ ⁴ ]¹∕ ⁴ =
= ( 0,694 * 1 * 1 )¹∕ ⁴ = 0,9127
Europa:
Tsat.mean = 102 K
[ (1-a)*(1/R²)*(N)¹∕ ⁴ ]¹∕ ⁴ =
= [ 0,37*0,0369*(1/3,5512)¹∕ ⁴ ] ¹∕ ⁴ = 0,3158
Let's compare
Earth coeff. /Europa coeff. =
= 0.9127 /0,3158 = 2,8902
And
Tmean.earth /Tmean.europa =
= 288 K /102 K = 2,8235
Conclusion:
Everything is all right.
It is a demonstration of the Planet Surface Rotational Warming Phenomenon!
Notice:
We could successfully compare Earth /Europa ( 288 K /102 K ) satellite measured mean surface temperatures because both Earth and Europa have two identical major features.
Φearth = 0,47 because Earth has a smooth surface and Φeuropa = 0,47 because Europa also has a smooth surface.
cp.earth = 1 cal/gr*°C, it is because Earth has a vast ocean. Generally speaking almost the whole Earth’s surface is wet. We can call Earth a Planet Ocean.
Europa is an ice-crust planet without atmosphere, Europa’s surface consists of water ice crust, cp.europa = 1cal/gr*°C.
Conclusion:
Everything is all right.
It is a demonstration of the Planet Surface Rotational Warming Phenomenon!
And
It is a confirmation that the planet axial spin (rotations per day) "N" should be considered in the (Tmean) planet mean surface temperature equation in the sixteenth root:
Tmean.planet = [ Φ (1-a) So (1/R²) (β*N*cp)¹∕ ⁴ /4σ ]¹∕ ⁴.
