“…For a 75Њ angle the error increases to about 0.5-0.7 K in the longwave infrared region (ϳ600-1500 cm Ϫ1 ) and Ϯ0.3 K in the shortwave (ϳ2400-3400 cm Ϫ1 ) infrared spectral region. Such a large polarization sensitivity does, in fact, exist in the infrared channels of the AIRS grating spectroradiometer (Pagano et al 2000;Gigioli and Pagano 1999).…”

“…FTIR instruments use beam splitters and mirrors that usually favor one polarization state over another, creating an instrument polarization sensitivity that can cause errors in radiometric measurements of partially polarized radiance when the instrument is calibrated with unpolarized sources. The potential for polarization errors contributing significantly to the error budget of modern infrared satellite sensors also has been recognized, particularly because of polarization-dependent scan mirrors and gratings (Pagano et al 2000;Gigioli and Pagano 1999;Knight et al 1999). This issue is complicated by the variability of the scene polarization S H A W FIG.…”

“…In (3), δ = δ y − δ x is the phase difference between the two components and the timespace propagator has been explicitly eliminated. Regardless, the electric field components E x and E y continue to be space and time dependent, and space and time define an instant on the curve described by (3). Equation ( 3) describes an ellipse with the major axis at an angle ψ to the x-axis, and is referred to as the polarization ellipse.…”

“…The potential for polarization errors contributing significantly to the radiometric uncertainty budget of infrared remote sounding sensors has been well recognized, particularly due to polarization-dependent scene select mirrors and for grating-and filter-based instruments [2][3][4][5][6]. The issue is equally applicable to FTS-based sensors.…”

“…For example, the use of infrared (IR) polarization is becoming increasingly common in remote sensing, especially for water, which is perhaps the most strongly polarized thermal IR source in nature [6]. Even non-polarimetric remote sensing applications for water require consideration of polarization when the sensor response varies with polarization [7,8]. Most passive remote sensors observe the brightness temperature or radiance, which contains the information about polarized reflectivities of a surface at a given view angle without having knowledge of the dielectric property of the material.…”
