Description

Important The underlying Open-Meteo file format has been upgraded to support future features. This change impacts only users of the open-data distribution on AWS and does not affect those using the API or running downloaders directly.

With this update, the API can now read both legacy and new file formats. Currently, only legacy files are available on AWS, but starting January 14, 2025, files in the new OM format will also be published on AWS. Users of the AWS distribution must upgrade their Docker images to version 1.4.0 or later.

The new Open-Meteo file format is designed to be more flexible and compatible with standards, similar to formats like NetCDF4 or HDF5. We are working on client libraries that will allow users to access curated Open-Meteo weather data directly from AWS S3, enabling data scientists to analyze data at large scales, such as entire countries or continents, without interacting with the API for individual data pieces.

This release marks the first step toward this vision, preparing Docker image users for the new file formats. Development of Python, Rust, and TypeScript libraries is ongoing and will take some time to complete.
