Data & map sources

Models support planning, not safety-critical decisions. Forecast and live layers show their own update times.

Geometry: Astronomy Engine, calibrated against JPL DE440s
Current Sun: NASA SDO/HMI and NOAA SWPC
Solar layers: NASA SDO/AIA, NSF/NSO GONG, NSF NCAR/MLSO K-Cor, NOAA GOES-19 CCOR-1/SUVI and ESA/NASA SOHO LASCO

Regional terrain: AWS Terrain Tiles and Copernicus GLO-30, selected per event
Site surface: IGN/CNIG PNOA-LiDAR MDS05 + MDT05, CC BY 4.0
Access, viewpoints & crowding: OpenStreetMap contributors via OpenMapTiles, Geofabrik and Overpass; official open-data viewpoint catalogues from Gobierno de Aragón and Gobierno de Navarra (CC BY 4.0); Overture Maps Foundation transportation data, Copernicus/JRC EMC-BUILT 2022, and JRC GHS-POP 2025
Foliage obstruction: Sentinel-2 10 m Land Use/Land Cover 2025 by Impact Observatory, Microsoft and Esri at global overview scale, refined by OpenMapTiles land-cover polygons when zoomed in.
Climatology: ERA5 1991–2020 via the Open-Meteo Historical Weather API, plus NASA POWER CERES cloud climatology for broad landfalls

Conditions now: Open-Meteo best-match model analysis, not an on-site sensor
Forecast: ECMWF IFS ensemble via Open-Meteo and AEMET HARMONIE-AROME
Observations: EUMETSAT MTG cloud/lightning and RainViewer radar
Hazards: NASA VIIRS/MODIS via Copernicus EFFIS V2, AEMET warnings, DGT traffic and CAMS air quality
