GeoColour RGB - MTG - 0 degree

Description

GeoColour is a visualisation that combines several satellite images with a static map. For the daytime part of the full disk, The True Colour RGB provides natural colours from the Earth and atmosphere during the daytime. The channels sensitive to the red, green and blue visible lights are visualised in the respective (human eye) colour beams. This results in realistic colours that imitate how the human eye might see the scene. Before creating the RGB, the effect of the Rayleigh scattering is removed from each band to prevent the RGB from being blurry. Aerosols are better seen in this RGB than in the other shortwave standard RGBs, as the scattering effect is stronger at shorter wavelengths. A special method is also applied to the FCI's green band to more precisely match the vegetated and forest areas. For the nighttime, FCI IR channel (10.5µm) and the fog difference (10.5µm - 3.8µm) are used to identify ice and liquid water clouds, shown in whitish and bluish colours, respectively. They are partially transparent and placed on the NASA Black Marble static background. Note that the Black Marble is a static layer, and it doesn't reflect the actual conditions of the city lights.
