A temperature-dependent hexagonal ice column far-infrared optical property dataset

The dataset contains single-scattering properties of severely surface-roughened hexagonal column ice particles in the far infrared (far-IR) wavelength region between 15 and 100 \mum. This particle shape is included in the database of Yang et al. (2013). The Invariant Imbedding T‐matrix Method (IITM) and the Improved Geometric Optics Method (IGOM) are used to perform the computation. Let x = 2 * pi * D / lambda, where D is the maximum dimension and lambda is the wavelength. IITM is used when x < 50; IGOM is used when x >= 50. Ice refractive index data are taken from the compilation of Wang et al. (2024).
