Can pyart grid using a fixed-earth (e.g. lat/lon = 1°/1°) rather than fixed-distance (e.g. x/y = 1km/1km)? I am hoping to be able to map to a user-specified grid that could then be easily compared to other datasets, such as MRMS or satellite data.

As of now, this is not possible, but something we should consider adding functionality for. I would encourage you to open an issue on the Py-ART repository [Issues · ARM-DOE/pyart · GitHub](https://github.com/ARM-DOE/pyart/issues)
