pyrcel.activation.binned_activation

pyrcel.activation.binned_activation(Smax, T, rs, aerosol, approx=False)

Compute the activation statistics of a given aerosol, its transient size distribution, and updraft characteristics. Following Nenes et al, 2001 also compute the kinetic limitation statistics for the aerosol.

Parameters:

Smax : float

Environmental maximum supersaturation.

T : float

Environmental temperature.

rs : array of floats

Wet radii of aerosol/droplet population.

aerosol : AerosolSpecies

The characterization of the dry aerosol.

approx : boolean

Approximate Kohler theory rather than include detailed calculation (default False)

Returns:

eq, kn: floats

Activated fractions

alpha : float

N_kn / N_eq

phi : float

N_unact / N_kn
