TranslationError: Grid definition template [32769] is not supported

ECCODES ERROR : Unable to find template gridDefinitionSection from grib2/template.3.32769.def

Hey @kuchaale, these lines indicate that the grib file is not correctly formatted. 32769 is not a valid template number, and suggests a bug in the file. As such nothing will be able to load in this file.

Hi @ESadek-MO, thanks for your prompt response. Nevertheless, is there any way how to generate the RAP full North American domain (also known as an “Arakawa staggered E-grid on rotated latitude/longitude grid”) in iris?

Would you be able to clarify what you mean by "generate"? Is that during loading, or just within Iris in general?
Please accept our apologies if there's a delay in replying!

I mean whether, in general, you can define such a grid using corner points etc. (see here).

Iris can read in rotated pole data fine - it's a common feature in meteorological models so its important for iris to handle and plot it. If the data you are trying to load is on a rotated pole and CF-compliant then iris should be able to try it. But iris isn't in the business of generating grid definitions from scratch - you may be able to do it but there's probably better tools for that need.
