scaling_lsd

Implements the Lifton-Sato-Dunai scaling scheme from Lifton et al. (2014)

scaling_lsd(h, Rc, SPhi, w)

Arguments

h

atmospheric pressure (hPa)

Rc

cutoff rigidity (GV)

SPhi

solar modulation potential (Phi, see source paper)

w

fractional water content of ground (nondimensional)

Details

Compute the scaling paramters for both the Sf (flux based) and Sa (flux ad cross-section based, nuclide dependent) schemes.
