• Added wavenumber (cm⁻¹) field to all satellite schemas
• Changed channel_index to sensor_index in E2STUDIO_SCHEMA
• Disabled Atlas example from documentation build due to slow performance

:hammer: Fixed

• Fixed potential uint16 underflow in UFS channel index expansion
• Fixed S3 upload bug in server utilities
• Fixed pres obs from UFS to be Pascal units
• Fixed chunk downloading race condition in file system cache for Zarr data sources
• Fixed 180° longitude misalignment in ECMWF open-data sources for some GRIB files with non-standard lon origin

📦 Dependencies
