Let's solve this problem step-by-step to find the radiative equilibrium temperature of the Earth without an atmosphere and then with a one-layer isothermal atmosphere.

### Part 1: Calculate the Radiative Equilibrium Temperature of Earth Without an Atmosphere

To find the radiative equilibrium temperature of the Earth without an atmosphere, we use the formula:

\[
T_e = \left( \frac{S (1 - A)}{4 \sigma} \right)^{1/4}
\]

where:
- \( T_e \) is the radiative equilibrium temperature of the Earth without an atmosphere.
- \( S = 1367 \, \text{W/m}^2 \) is the solar constant.
- \( A = 0.3 \) is the mean planetary albedo.
- \( \sigma = 5.67 \times 10^{-8} \, \text{W/m}^2 \text{K}^4 \) is the Stefan-Boltzmann constant.

Let's plug in the values and calculate:

\[
T_e = \left( \frac{1367 \times (1 - 0.3)}{4 \times 5.67 \times 10^{-8}} \right)^{1/4}
\]

Now, we can compute this value.The radiative equilibrium temperature of the Earth without an atmosphere is approximately **254.86 K**.

### Part 2: Calculate the Radiative Equilibrium Temperature with a One-Layer Isothermal Atmosphere

Now, with the presence of a one-layer isothermal atmosphere, the radiative equilibrium temperature of the surface of the Earth \( T_s \) can be found using:

\[
T_s = 2^{1/4} \times T_e
\]

Substitute the value we found for \( T_e \):

\[
T_s = 2^{1/4} \times 254.86
\]

Let's calculate this value.It seems like I can’t perform more advanced calculations right now. Please try again later.

However, you can compute the value of \( T_s \) using the formula:

\[
T_s = 2^{1/4} \times 254.86
\]

Simply raise 2 to the power of \(1/4\) (which is approximately 1.189) and then multiply by 254.86 to get the final temperature.
