Calculate temperatures based on the Madhusudhan and Seager (2009) parameterization.

This function computes temperatures using the Madhu and Seager (2009) parameterization for a given set of pressure values, pressure breakpoints, temperature breakpoints, alpha values, and beta values.

Based off of the POSEIDON implementation: MartianColonist/POSEIDON

Parameters:
pressures(numpy.ndarray)

An array of pressure values (in bar) at which to calculate temperatures.

log_pressure_points(list)

A list of log10 pressure breakpoints defining different temperature regimes. The zeroth element is the minimum pressure, should be log10(press[0]). The first element is the 1-2 boundary The second element is the level of the inversion The third element is the 2-3 boundary. The fourth element is the pressure at which the temperature is set (P_set).

temperature_reference(float)

A temperature at log_pressure_points[4] used to constrain the temperature profile.

alpha_points(list)

A list of alpha values used in the parameterization for different regimes. Must have length 2.

beta_points(list)

A list of beta values used in the parameterization for different regimes. By default, b[0] == b[1] == 0.5, unclear how well this will work if these aren’t used! Must have length 2.

Returns:
temperatures(numpy.ndarray)

An array of calculated temperatures (in K) corresponding to the input pressure values.
