Refractive indices (500-3500 cm-) and emissivity (600-3350 cm-1) of pure water and seawater

Abstract

Tables of infrared refractive indices have been compiled and calculations made of emissivity for pure water and seawater (35 PSU), suitable for radiative transfer simulation of observations of thermal imagers, such as the series of Along Track Scanning Radiometers. The refractive indices are tabulated as a function of wave number (500–3500 cm-1) and temperature (274, 287, and 300 K). The emissivities are tabulated as a function of wave number (600–3350 cm-1), view angle (0–85°), temperature (270–310 K), and wind speed (0–25 m s-1 at 12.5 m).
