MAST Data Catalog

MAST Data Catalog#

This is the documentation for using the MAST data catalog. MAST stands for the Mega Ampere Spherical Tokamak. This site provides documentation for accessing historical data and meta data from MAST. Here you can find descriptions and examples of how to load the data and metadata, which are stored as Zarr and Parquet files in a public S3 bucket (s3://mast, endpoint https://s3.echo.stfc.ac.uk). Start with the Quickstart, or see Metadata for the metadata files.

Tutorials#

Below are tutorial notebooks showing examples of how to query metadata and load data from the catalog.
