Geostationary Ring Natural Colour RGB - Multimission

This visualization is composed of a 3-hourly imagery of RGB Natural Colour products from different geostationary satellites: Meteosat 0 Degree and Meteosat IODC, GOES-16 and GOES-17, Himawari-8. Every single imagery composing the final product, is generated by assigning red, green and blue to imageries from solar and visible and near-IR channels from the following instruments: - SEVIRI (Meteosat): NIR1.6, VIS0.8 and VIS0.6 channels. - ABI (GOES-16 and GOES-17): NIR1.6, VIS0.86 and VIS0.64 channels. - AHI (Himawari-8): NIR1.6, VIS0.86 and VIS0.64 channels. 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.
