Portable Fourier transform infrared spectroradiometer for field measurements of radiance & emissivity

February 24, 2009

By Andrew R. Korb, Peter Dybwad, Winthrop Wadsworth, and John W. Salisbury ABSTRACT A hand-held, battery-powered Fourier transform infrared spectroradiometer weighing 12.5 kg has been developed for the field measurement of spectral radiance from the Earth’s surface and atmosphere in the 3–5-µm and 8–14-µm atmospheric windows, with a 6-cm21 spectral resolution.

Effects of atmosphere, temperature and emittance on reflected and emitted energy

September 4, 2007

A NASA report by R. Kumar, dated Sep 1, 1977, available online and downloadable as a PDF document. ABSTRACT: The effects of temperature and emittance on the relative magnitude of reflected energy and emitter energy from a target including atmospheric effects was studied. From the calculations of energy reflected and emitted from a target including [...]
