Hi @nbren12 and @phausamann , Thanks for jump-starting this discussion. My approach is an odd combination of your all's; I implemented it for a project [here](https://github.com/darothen/stat_pm25). The basic idea is...

Yes, it's quite easy. [Here's a function to convert longitudes in (180, 360\]](https://github.com/darothen/darpy/blob/db829049aed4d846c7635ee29277a3b4524c7dfa/darpy/utilities.py#L308), then you would just use `xarray.DataArray.roll.()` along the longitude dimension, by length(longitude) - 1 units.

This is fantastic... I tried this out with two of NOAA's operational datasets archived on GCS and it worked without any modifications, but was much slower (for calibration, the MWE...

Tag @blaylockbk - his package [Herbie](http://www.github.com/blaylockbk/Herbie/) has some nascent capability to do partial decoding of HRRR grib files, could be a starting point here. Somehow the [`grib_ls`](https://confluence.ecmwf.int/display/ECC/grib_ls) tool that ships...

Not sure, I'm digging for the source code to read through right now.

I spent the last hour digging through the source code for the [`grib_ls`](https://confluence.ecmwf.int/display/ECC/grib_ls) tool... it's a pretty dense C program which directly scans through the GRIB file(s) that are passed...

This seems pretty useful; I've been playing around with this during the evening, and it looks like fsspec/kerchunk#198 would unblock writing recipes that read from remotely hosted GRIB files. Directly...

A quick update - I was able to hack out a minimal working example of using the existing `HDFReferenceRecipe` class to read GRIB2 files. The demo code is in #390,...

Another quick update - I started re-factoring a generic `ReferenceRecipe` so that the custom code for each file format could be added in. In general things "just work", but debugging...

No worries @rabernat. This project is really just an excuse for me to get much more comfortable with the internals of `fsspec` / `kerchunk`. I don't think this work will...
