Corrigendum to “Background Radiance Estimation for Gas Plume Quantification for Airborne Hyperspectral Thermal Imaging”

Abstract

In the article titled "Background Radiance Estimation for Gas Plume Quantification for Airborne Hyperspectral Thermal Imaging" [1], there are some errors in Figures 2(b), 10, 15, and 16. In Figure 2(b), the emissivity of "slate stone shingle" is absent. Moreover, the emissivities of some materials have been misnamed. In Figure 10, there is a confusion between the curves of the methods CB and SB. In Figures 15 and 16 the curves' order in the legend has been modified. The corrected figures are shown as follows. (Figure Presented).
