At the beginning, I was so confused about the idea of atmospheric windows. After referring to textbooks and literature, I got a better understanding of it. The Earth’s atmosphere selectively transmits energy of certain wavelengths and those wavelengths that are easily transmitted through the atmosphere can be referred as atmospheric windows (Fig.2) (Campbell, 2011). This means only radiation in these wavelengths can be transmitted through the atmosphere and the others are blocked. Thus, these wavelengths are detected by remote sensing satellites and form the basis of remotely sensed images
