Description
Hello @wesselb
I am currently forecasting 2-meter temperature using the Aurora model. The model outputs data on a global grid with the following configuration:
Latitude: ranges from 90° to −90° (descending order).
Longitude: ranges from 0° to 360°.
Data shape: [time, lat, lon] → [t, h, w].
For my application, I need to reformat the output to use the conventional geographic coordinate system:
Latitude: increasing from −90° to 90°.
Longitude: shifted to −180° to 180°.
Data shape remains [t, h, w].
What is the correct approach to transform the model output into this desired coordinate system?

Research direction
No file, test, or entry point is named. Start by locating Aurora’s output-coordinate handling and any existing coordinate documentation; done means providing a validated transformation approach for the requested latitude and longitude conventions while preserving the [time, lat, lon] shape.
