PyPSA-Eur weather cutouts
pypsa
Pre-cut ERA5 weather slices covering Europe, packaged for direct use by atlite in PyPSA-Eur workflows.
Before you use this
- Derived from ERA5. Pairing these cutouts with any other ERA5-derived product produces correlated inputs, and the apparent agreement between them is partly ERA5 agreeing with itself.

- Currency & maintenanceAging
Regional extracts of ERA5 prepared as atlite cutouts, so a PyPSA-Eur run does not have to download and subset the reanalysis itself. The cutouts carry wind speed, irradiance, temperature and runoff on the ERA5 grid, restricted to the European domain and to the years the workflow needs. Because they are extracts rather than a re-simulation, every value traces directly to ERA5 — which is what makes this dataset and any other ERA5-derived product correlated rather than independent.

The exclusions are the half you cannot get anywhere else. A dataset that is wrong for your question is worth knowing about before you build on it.

The catalog says why, rather than leaving the cell blank.
Three independent facets
Graded separately and never combined. A dataset can be perfectly current and completely unprovenanced, and one number would hide exactly that.
Provenance
BDerived & Traced
Values are modeled with full lineage to a recorded origin.
Documentation
AFully documented
All 2 attribute field(s) carry a definition and a unit where one applies. Allowed ranges are not assessed: the fields that carry them are deferred (PRD §4.3), so no record in this catalog states one and grading against them would mark every record down for the same absent field.

OpenGrid redirects you to the source and never proxies the bytes. For a partial read of a large dataset, use the SDK — it fetches an access plan and reads only the slice you asked for.
