PURPOSE ^

N_ICE_WARREN08 Complex refractive index for ice

SYNOPSIS ^

function n = n_ice_warren08( lambda )

DESCRIPTION ^

 N_ICE_WARREN08   Complex refractive index for ice

    This parameterisation is a compilation and merge of data across the EM
    spectrum. The valid wavelength range is 44 nm to 2 m. The data are
    valid for 266 K, no temperature variation is included.
