The referenced URL mentions this data is a resampled version of the L1B data. It sounds like it is resampled to the 89GHz A channel, not a uniform grid. Does that sound right? So you still have a "swath" of pixels, right?

Yes, it is a swath, very similar to l1b, but with some brightness and alignment corrections.

Sorry for closing, accidentally touched the wrong part of the screen..

I also have code for another modis l2 product - mod29 - let me know if you want a pr!

Looks like you'll also need to fix the issues that pre-commit is talking about. You could also have it do that locally when you make a commit:

pip install pre-commit
pre-commit install

then every commit after that will run our pre-commit checks before letting you successfully making a commit.

For the MODIS changes, feel free to make a PR to update the modis_l2 reader with the new file type.
