This function takes the temperature gradient at a set number of spline points and interpolates a temperature profile as a function of pressure. Based on the method described in Zhang et al. (2023).

Args:

pressures: The pressure array in bar. num_layer: The number of layers. Default for covering 10^3 to 10^-3 bar as in Zhang 2023 is 6.

To cover 10^3 to 10^-6 bar 10 is recommended.

layer_pt_slopes: The temperature gradient (d(ln T) / d(ln P)) at the spline points. t_bottom: The temperature at the bottom of the atmosphere. top_of_atmosphere_pressure: Minimum atmospheric pressure in log bar. If the pressure array extends

beyond this value, the temperature structure at lower pressures will be isothermal.

bottom_of_atmosphere_pressure: Maximum atmospheric pressure in log bar.

Returns:

The temperature profile in K.
