Calculate the surface temperature $(T_s),$ the temperature of the first layer $(T_{a1}),$

and the temperature of the second layer$(T_{a2})$ if the planet has two multiple

isothermal atmospheric layers, as shown in the figure below. Assume that

the atmosphere has an albedo of $0\mathrm{.}3$ for solar radiation and $0$ for terrestrial

radiation$($i$.$e$.,{}_{\text{s}\text{o}\text{l}\text{a}\text{r}\text{r}\text{a}\text{d}}=0\mathrm{.}3$ and ${}_{\text{t}\text{e}\text{r}\text{r}\text{e}\text{s}\text{t}\text{i}\text{r}\text{a}\text{l}\text{r}\text{a}\text{d}}=0).$
