Anyone played with weather satellite Himawari 8?

Grayscale Wutip was taken at the highest resolution which is red at 644nm - 0.5km per pixel. The problem the infrared bands is that they are lower resolution. For fine detail, you need to keep the red band. Old RGB astronomy trick, you can keep the high resolution image for RGB colour, even though lower resolution bands are used, if the highest resolution channel is stacked onto the low res colour composite as a luminance layer. Choose whatever channels for chrominance.

For Himawaricast, they don't include blue or green so a false colour image has to be made from 2 infrared and one visible. This causes the cyan clouds. Sometimes I desaturate then to make them look more natural.
