Data offered docs-verified: 10 m U wind component (u10, m s⁻¹) · 10 m V wind component (v10, m s⁻¹) · 2 m temperature (t2m, K) · Mean sea level pressure (msl, Pa)
Coverage llm-inferred: Global · 2010-01-01 00:00 UTC to 2020-12-31 18:00 UTC
Resolution docs-verified: Spatial: 0.25° (~28 km) HR target; 1.0° (~111 km) LR input. Temporal: 6-hourly
Formats docs-verified: zarr (ZipStore) · JSON
Access docs-verified: Open: CC BY 4.0 licence; no authentication (ENTRY auth null)

Use cases llm-inferred: Benchmarking ML super-resolution downscaling of 1° reanalysis to 0.25° for regional wind and temperature baselines · 2010–2020 historical wind and mean sea level pressure context for storm or coastal exposure screening · 2 m temperature series for heat-risk or thermal-comfort baseline screening
Audience llm-inferred: climate and meteorological data scientists · hydrologists · drainage engineers · GIS analysts

Constraints llm-inferred: 0.25° (~28 km) grid is too coarse for site-scale UK analysis without local data · Only 2010–2020 and only four variables (u10, v10, t2m, msl) · Built for ML training; LR fields are bicubic-downsampled from HR, not independent observations · train_stats.json must be present for normalize=True · Dataset card reports conflicting sizes ("< 1K" in header vs 258 GB total)
