gradient_search comb effect

I’m guessing this is an issue with precision in the grid position with the gradient resampling with such a jump in resolution. Could you try to reproduce this error with...

gradient_search comb effect

@twak thanks for the minimal example and the data. I will try to have a look at this next week.

Can the true_color composite method used by satpy for Himawari HSD data be applied to Himawari L1 data to generate output consistent with the HSD true_color composite?

As long as the data is the same but just a different format, and provided there is a reader for it, then it should be exactly the same.

Issues about fog composites

@ZitaTan I think the fog composite in satpy is the 24h microphysics, which you can read more about here https://resources.eumetrain.org/rgb_quick_guides/quick_guides/24MicroRGB.pdf

Is it possible to have acquisition time variable for geostationary images like goes and himawari?

@akasom89 it would be great to have times in satpy too…

Definition and accuracy of reflectance

With the merging of https://github.com/pytroll/satpy/pull/3292 we will be closing this, since we now accurately make a distinction between reflectance, and the non-sunz-normalised reflectance. Regarding the sun-earth distance correction, it should...
