In this colour scheme vegetation appears greenish because of its large reflectance in the VIS0.8 channel (the green beam) compared to the NIR1.6 (red beam) and VIS0.6 (blue beam) channels. Water clouds with small droplets have large reflectance at all three channels and hence appear whitish, while snow and ice clouds appears cyan because ice strongly absorbs in NIR1.6 (no red). Bare ground appears brown because of the larger reflectance in the NIR1.6 than at VIS0.6, and the ocean appears black because of the low reflectance in all three channels.Visible Africa Atlantic ChartsVisible Southern Africa Atlantic ChartsVisible Africa Indian Ocean ChartsVisible Southern Africa Indian Ocean ChartsDAY MICROPHYSICS RGB - only visible in daylightClouds that won't precipitate appear white. Clouds with larger drops that may rain appear pink. Super-cooled clouds appear more yellow. Cold and thick clouds with tops composed of large ice particles appear red. Optically thick clouds with small ice particles near their tops appear orange.Africa Atlantic ChartsClouds that won't precipitate appear white. Clouds with larger drops that may rain appear pink.
