Zephyr

Zephyr is C2SM’s climate data extraction service for datasets stored at IAC (ETH Zurich). Users select a dataset, variables, a date range, and either a grid point or a bounding box in a web interface; the request is processed on an IAC machine and the extracted data is returned as NetCDF.

This site documents the whole ecosystem — not just the zephyr Python package. Start with The Zephyr Ecosystem for the big picture, then jump to whichever page matches what you’re trying to do:

Use the web interface

Browse datasets and build a request in zephyr-frontend, without installing anything.

Run it yourself

Install zephyr locally or on an IAC machine (e.g. co2) and run an extraction from the command line.

Request format

The JSON schema a request file follows, field by field.

Supported datasets

Which datasets and scenarios can be extracted, and how grid types are handled.
