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.
Tmean.europa
So = 1.361 W/m² (So is the Solar constant)
Europa’s albedo: aeuropa = 0,63
Europa is an ice-crust planet (rocky) without atmosphere, Europa’s surface irradiation accepting factor Φeuropa = 0,47
Europa’s surface consists of water ice crust
Cp.europa = 1cal/gr*oC
1/R² = 1/5,2044² = 0,0369 times lesser is the solar irradiation on Jupiter than that on Earth, the same on its satellite Europa.
Europa’s orbital period is 3,5512 d
Europa’s sidereal rotation period is synchronous
N = 1/3,5512 rotation /day
β = 150 days*gr*oC/rotation*cal – it is the Planet Surface Solar Irradiation INTERACTING-Emitting Universal Law constant
σ = 5,67*10⁻⁸ W/m²K⁴, a Stefan-Boltzmann constant
Europa’s mean surface temperature equation Tmean.europa is:
Tmean.europa = [ Φ (1-a) So (1/R²) (β*N*cp)¹∕ ⁴ /4σ ]¹∕ ⁴
Τmean.europa = { 0,47(1-0,63)1.362 W/m² *0.0369*[150* (1/3,5512)*1]¹∕ ⁴ /4*5,67*10⁻⁸ W/m²K⁴}¹∕ ⁴ =
Tmean.europa = 99,557 K
Tsat.mean.europa = 102 K (- 171 oC)

The faster a planet rotates (n2>n1) the higher is the planet’s average (mean) temperature T↑mean:
Tmin↑→ T↑mean ← T↓max

Io and Europa
Io and Europa is an example of the planet or moon surface temperatures comparison:
Io and Europa are at the same distance from the sun. Both have the same satellite measured Albedo.
Io (Jupiter's satellite), Albedo a =0,63
Flux _ 50,37 ( W/m² ) Te = 95,16 K
Te.correct = 95,16 K, Φ = 1
Warming Factor (β*N*cp)¹∕ ⁴ = 1,8647
Tsat = 110 K
Europa (Jupiter's satellite), Albedo a =0,63
Flux _ 50,37 ( W/m² ) Te = 95,16 K
Te.correct = 78,83 K, Φ = 0,47
Warming Factor (β*N*cp)¹∕ ⁴ = 2,5494
Tsat = 102 K
110K /102K = 1,0784
[ (1*1,8647 ) /(0,47*2,5494) ]¹∕ ⁴ = 1,1169
1,1169 /1,0784 = 1,0357 or 3,57 %
