Strong reflection of sunlight can also give rise to yellowish shades and these are not related to haze.

O sinal modulante é To help identify and highlight different features such as hotspots, smoke plumes/haze and clouds, the data from a combination of spectral channels are used to form a multi-spectral image.Three primary colours of red, green, blue (RGB) are assigned to selected spectral channels of NOAA, AQUA and TERRA satellites.
