Greptile Overview

Greptile Summary

Adds a new example demonstrating how to create and use a local Zarr data source for inference pipelines. The example shows fetching data from WeatherBench2, storing it locally, and using it with the Pangu model.

• Well-structured example with clear documentation sections
• Demonstrates practical workflow: fetch → store → load → infer → visualize
• Critical issue: Variable name typo on line 101 (coods instead of coords) will cause runtime error

Confidence Score: 3/5

• This PR adds useful functionality but contains a syntax error that will prevent the example from running
• The example is well-written and follows established patterns, but the variable name typo (coods vs coords) on line 101 will cause a NameError when the code executes line 108. Once fixed, this would be a solid addition
• Fix the typo in examples/19_local_datasource.py before merging
