Brightband ECMWF IFS 0.25 degree initial-condition data source on Earthmover Arraylake.

Parameters:

  • repo (str, default: None ) –

    Arraylake repository name as org/repo. When omitted, derives the repo from EARTHMOVER_ORGANIZATION as <org>/ecmwf-ifs-initial-conditions-open-subscription, by default None.

  • branch (str, default: DEFAULT_BRANCH ) –

    Repository branch to read, by default "main".

  • client (AsyncClient, default: None ) –

    Pre-authenticated Arraylake async client. When omitted, this data source uses the API key stored in EARTHMOVER_API_KEY, by default None.

  • cache (bool, default: True ) –

    Retained for API compatibility; Arraylake reads lazily via Icechunk, by default True.

  • verbose (bool, default: True ) –

    Print progress, by default True.

Warning

This is a remote data source and can download a large amount of data for large requests.

Note

Configure Earthmover access before using this data source:

  • Set the EARTHMOVER_API_KEY environment variable to an Earthmover / Arraylake API key, unless passing a pre-authenticated client.
  • Pass repo="org/repo" to open a specific Arraylake repository.
  • If repo is omitted, set the EARTHMOVER_ORGANIZATION environment variable. The default repository is <EARTHMOVER_ORGANIZATION>/ecmwf-ifs-initial-conditions-open-subscription.

Arraylake-backed Earthmover sources require Python 3.12 or newer.
