seasons the average proportion of pixels picked up was highest in the range −11 to −7 dB; rainy season recorded lower percentage than the winter season. Moreover, for both the seasons, in the range−11 to −7 dB, maximum pixels registered values greater than −8 to −7 dB (Fig. 6a). Distribution of >−7 to −2 dB pixels was more in the Bangladesh Sundarbans than in the Indian counterpart (Fig. 5n) and their proportion was relatively more in the rainy season (Fig. 6a).
