Develop an hourly model

Thanks for and congratulations on the great work here!

I'm probably not the only person excited to use GraphCast but limited by the 6 hour resolution. I work in the energy sector. Forecasting the shape of electricity prices across the day matters a lot to battery revenue, and is highly dependent on weather. Accuracy at ~hourly resolution probably determines when generic weather apps can switch to new models, too.

So, the feature request is to develop a model with hourly rather than 6-hourly resolution. I'm sure you're already considering this but thought I'd submit a formal issue so those of us interested can follow along.
