Assertion

Geospatial data referenced to the WGS84 ellipsoid: Earth-observation imagery, oceanographic and atmospheric fields, biodiversity occurrence records, and any data product whose coordinates are given as geographic latitude/longitude on the WGS84 datum.

Assertion

Integrated multi-source data stacks combining biodiversity occurrence records (GBIF, OBIS, biodiversity atlases) with high-resolution Copernicus EO products and Destination Earth climate-model output.

Assertion

Globally-distributed sea-surface-temperature fields on the sphere with marine-heatwave events occurring at any latitude.

Assertion

Coastal Natura 2000 marine sites (SACs and SPAs with marine area > 0) designated under the EU Habitats and Birds Directives. The population covers three European basins affected by the storms shown: the French Atlantic coast (Bay of Biscay, Pertuis Charentais), the southern North Sea and German Bight (Wadden Sea), and the north-western Mediterranean (Catalan coast and Ebro Delta).

Assertion

Systems managing Earth observation data collections composed of heterogeneous scene-level arrays paired with per-granule metadata, where data and metadata must remain mutually consistent across updates.

Assertion

Optical multispectral satellite imagery of landscapes containing many small open-water bodies — here Landsat surface-reflectance scenes of the Arctic Coastal Plain of northern Alaska, a terrain dense with thermokarst ponds.

Assertion

Gridded fields of integrated water-vapour transport (IVT) from the ERA5 reanalysis (here the North Pacific, early February 2017, 6-hourly, 0.25 degrees), in which atmospheric rivers appear as long narrow filaments of high IVT.

Assertion

Earth-observation optical satellite imagery (multispectral surface-reflectance scenes) at regional scale.
