ECMWF Open Data Client

ecmwf-opendata is a Python package designed to simplify the download of ECMWF open data. It provides a request-based interface similar to ECMWF's MARS language for selecting meteorological fields. The library is actively maintained (current version 0.3.26) and receives frequent updates, with new releases typically addressing data source changes, bug fixes, and supporting new data streams. It allows users to retrieve data from ECMWF's direct servers as well as cloud replicas on AWS, Azure, and Google Cloud Platform.
