AlphaEarth embedding-window archive for: The limits of ecological decodability of a geospatial foundation-model embedding: a registered evaluation of AlphaEarth over shallow Great Barrier Reef habitats.

The exact AlphaEarth Foundations satellite-embedding windows used in: Cropp, A. (2026). The limits of ecological decodability of a geospatial foundation-model embedding: a registered evaluation of AlphaEarth over shallow Great Barrier Reef habitats. EarthArXiv preprint. Archived so every result remains reproducible against its exact inputs even if the upstream Earth Engine collection is revised. Contents: 8,670 window files (8,669 single-year .npz windows + one Heron multi-year stack; 10.37 GB), zipped by site family into nine zips (windows_site, windows_manta, windows_dash, windows_nrmn, windows_pan, windows_pan19, windows_dose, windows_aca, windows_heron), plus windows_manifests.zip holding the per-file manifest (embedding_windows_MANIFEST.csv: site, year, shape, CRS, bounds, affine transform, per-file source URL, retrieval timestamp, SHA-256), the per-year distribution identifiers (per_year_sources.csv), the zip-level SHA-256 manifest (archive_zips_MANIFEST.csv) and the build script. Each .npz holds q (int8, 64 × H × W), the distributed 8-bit quantised embedding, with georeferencing keys; the dequantisation formula is in the manifest README inside the reproduction pack. All windows are from the v1 annual collection (model version 2.1), retrieved from a public cloud-optimised CC-BY 4.0 redistribution; the canonical asset is Earth Engine GOOGLE/SATELLITE_EMBEDDING/V1/ANNUAL. To verify any file, re-hash it and compare against the manifest. The AlphaEarth Foundations Satellite Embedding dataset is produced by Google and Google DeepMind and is redistributed here under CC BY 4.0 with that attribution (Brown et al. 2025, arXiv:2507.22291).
