Detailed Description
Not much detail in the blog, only architectural thing they include is switching to a HEALPix grid from lat/lon grid for inputs and processing. Would be worth adding HEALPix for the models that take in grids, Nvidia's cBottle also uses HEALPix, and I think so did the Excarta paper.
Context
Really good forecasting results if it holds up, they eventually released the WeatherMesh-3 code, but seems like they might be even more secretive with this one? The WM-3 blog had some interesting details and went into enough detail to try to reproduce it, this doesn't, unless the only change is the HEALPix grid.
