If you've been looking for a quick way to make some GOES composites (e.g. geocolor, airmass), here's a notebook showing how to do it using SatPy and AWS S3 data (optionally a little bit of the next @metpy.bsky.social release). gist.github.com/dopplershift...

After fumbling around with SatPy API and throwing the entire kitchen sink into Spyder, I've managed to get Himawari-9 data from the AWS servers. Here's a look at Typhoon Gaemi as it approached Taiwan in July of this year.

Looks great!
It's just a bummer that GOES data has the atmosphere clipped away. HIMAWARI data doesn't do that, but last I checked, satpy is not able to preserve it anyway...

Yeah, that was my goal too.
At some point you'll have to dig into the composite and enhancements definitions if you want to understand what they do exactly.
I can also recommend joining the satpy slack server, people were very helpful there last time.

SatPy is good if you have an established processing method and need to run it on a bunch of timestamps, but tweaking it's output "until the image looks right", it was very tedious.
Maybe newer tools like GEE are easier in that regard, but I can't speak to that.

I used satpy a few years ago to process GOES data with good color representation.
I remember having to define my own composite "recipe" since the default ones didn't quite look the part. SatPy is certainly capable of what you're trying to do, if you want I can try to find my old code.

New experiment: instead of writing a whole blog post every time I learn something interesting, or just posting it on social media (which doesn't work well for code or nuance), I'm going to try just writing a "TIL"-style quick post.

The long wavelength channels show up oil wells nicely just by visualising the channel alone (I use satpy / pytroll). The short wavelength channels need a lot of aggregation and denoising.
There was another test on 9th, by the way, at around the same time.
