Hydrosol optical properties refractive index physical quantities

Description

The hydrosol dataset is a look up table for the single scattering properties of hydrosol. It covers the range of refractive indices and sizes of natural hydrosol.

Methods & Sampling

The invariant-imbedding T-matrix mathod(IITM)[1] is used to compute particles with equivalent volume sphere radius from 0.001~2.0 um. The physical geometric optics method(PGOM)[2] is used to compute particles with equivalent volume sphere radius from 2.1~300.0 um. The particle geometry is generated with the "irregular hexahedral ensemble" method[3]. Single scattering properties of a single particle is obtained by averaging a 20-irregular-hexahedron ensemble.

Data Processing Description

BCO-DMO Processing Notes:
- combined all isca.dat files
- created a column for file name from which the data was gathered
- added conventional header with dataset name, PI name, version date
- modified parameter names to conform with BCO-DMO naming conventions
- sorted data by filename and eq_vol_sphere_rad columns
