![]() ![]() ![]() The DoP combined with AOP is often used to calculate the celestial compass information in the absence of GNSS (Global Navigation Satellite System). This also indicated that the symmetric line suffered a change. ![]() It should be noted that there are two unpolarized areas in Figure 1h-j. The lowest DoP area was located at the position left of the lunar-anti-lunar meridian and right of the lunar-anti-lunar meridian, as can be observed from Figure 1d-g, respectively. Additionally, the lowest DoP area (usually the region around the neutral point) was not located in the lunar-anti-lunar meridian. The dots and solid lines represent the values of DoP and their fitted curve, respectively. (a-j) corresponding to the recording time on 31 January in Table 2. As a conclusion, it is suggested that the variation of the polarized skylight during the SBBM should be considered in atmospheric model calculation for nocturnal biological activity and navigation information computation.ĭegree of Polarization (DoP) corresponding to the direction parallel to the lunar-anti-lunar meridian. The AoP is no longer symmetrical about the celestial meridian. The value of DoP gradually decreases as the obscuration ratio of the Moon increases. As a result, SBBM polarization patterns change at the beginning of the partial eclipse, and the neutral points vary from traditional neutral points. From the analysis of the relative variation of the celestial polarization characteristics including the Degree of Polarization (DoP) and Angle of Polarization (AoP), the changes of the extremum, frequency, symmetric line, and neutral points are discussed. The polarization patterns under the SBBM are collected, analyzed, and compared with both those generated by the ideal single-scattering Rayleigh model and those in the normal sky. ![]() This study analyzes celestial polarization patterns generated by the Super Blue Blood Moon (SBBM) through several comparative studies. Although intensive studies on clear sky, foggy sky, and even total solar eclipse sky have been conducted, the polarization distribution generated by the moonlight has not been well investigated. Investigating celestial polarization patterns in the case of different environments is important for exploring the atmospheric radiative transfer mechanism. ![]()
