Data sources & credits

Last updated: August 2026

• Current, hourly and daily weather data (temperature, wind, cloud cover, precipitation probability, visibility, sunrise/sunset) is provided by Open-Meteo, licensed under CC BY 4.0. Open-Meteo aggregates data from national weather services including NOAA, DWD, ECMWF and others.
• Alternate weather models/sources selectable via the weather-model picker (where enabled) are provided by Open-Meteo's model selection (ECMWF IFS, NOAA GFS, DWD ICON) and MET Norway, the Norwegian Meteorological Institute's open Locationforecast API.
• City search tries Google Geocoding first when configured (best accuracy for fuzzy/partial place names, capped by our own monthly budget — see our About page), falling back to the Open-Meteo Geocoding API, then LocationIQ for small villages/hamlets neither of those has.
• Reverse geocoding (converting your coordinates into a place name) tries Google Geocoding first when configured, falling back to LocationIQ (its OpenStreetMap-based data resolves small villages/hamlets that a municipality-level lookup can miss), then the free BigDataCloud reverse-geocode API once both are unavailable or their quotas are used up.
• Air quality (US AQI) data is provided by the Open-Meteo Air Quality API, also licensed under CC BY 4.0.
• The seasonal statistics on our location pages come from the ERA5 reanalysis of the Copernicus Climate Change Service (ECMWF), retrieved through the Open-Meteo Historical Weather API. Contains modified Copernicus Climate Change Service information, 2026.
• Planetary Kp index (geomagnetic activity) data — the official 3-hour planetary Kp shown as the primary figure, plus NOAA's faster-updating 1-minute estimated nowcast shown as a secondary reference — is provided by NOAA's Space Weather Prediction Center, a public service of the U.S. government. An alternate Kp source, where enabled, is provided by GFZ Potsdam, licensed under CC BY 4.0.
• Visible-satellite counts are computed from GPS/GLONASS/Galileo orbital element sets (TLEs) published by CelesTrak, propagated using the open-source satellite.js library (SGP4/SDP4). Daylight/twilight timing is computed with the open-source SunCalc library.
• The map page is rendered with the open-source Leaflet library. Its "Road" base layer is OpenStreetMap tiles (ODbL license); "Satellite" and "Hybrid" use Esri World Imagery and Reference/Boundaries-and-Places tiles (Esri, Maxar, Earthstar Geographics, and the GIS User Community).
• Where configured, the map's airspace overlay is provided by OpenAIP, a free, community-maintained worldwide aeronautical database, licensed CC BY-NC 4.0. This is aviation-chart data built for manned-aircraft pilots, not simplified for drone flying — see our airspace page for how to read it.
• Where enabled, the map's precipitation radar overlay is provided by RainViewer, real composite radar data updated roughly every 10 minutes.
