GeoSphere Austria Weather

Get air quality for a location: pollutants now and the AQI outlook. Reports current NO₂, O₃, PM10 and PM2.5 surface concentrations plus the European Air Quality Index (1-6 EEA bands) for today, tomorrow and in two days. GeoSphere's WRF-Chem forecast (3 km) serves Austria and the Alpine region only; a point outside that grid returns an out-of-coverage notice. These are model forecasts, not station measurements. An in-coverage point can still come back empty when a WRF-Chem run is stale or incomplete — the response then says so and names the source that drew the blank, which is a different answer from being out of coverage. Args: latitude: Decimal latitude (e.g. 48.2208 for Vienna). Geocode city names to coordinates yourself. longitude: Decimal longitude (e.g. 16.3738 for Vienna).

Get current weather conditions for a location. High-resolution GeoSphere Austria data (AROME/INCA/nowcast). Serves Austria and the Alpine region only; a point outside that grid returns an out-of-coverage notice. The response states which datasets served it. Observations decide whether and what is falling; the rest of the condition comes from GeoSphere's weather symbol for the current hour. Args: latitude: Decimal latitude (e.g. 48.2208 for Vienna). Geocode city names to coordinates yourself. longitude: Decimal longitude (e.g. 16.3738 for Vienna).

Get an hour-by-hour weather forecast for a location. High-resolution GeoSphere AROME data (1 km, up to ~60 h). Each hour's condition is GeoSphere's own weather symbol; the precipitation chance is an estimate derived from C-LAEF ensemble percentiles (0/30/70/95 %), not a probability GeoSphere publishes. Serves Austria and the Alpine region only; a point outside that grid returns an out-of-coverage notice. Args: latitude: Decimal latitude (e.g. 48.2208 for Vienna). Geocode city names to coordinates yourself. longitude: Decimal longitude (e.g. 16.3738 for Vienna). hours: Number of forecast hours (default 24, clamped to 1–60). start: Optional ISO 8601 start time (e.g. "2026-07-22T15:00"); the forecast begins at/after this instant instead of now. Without an offset it is Vienna local time, like the times in the output.

Get the severe-weather outlook for a location: gusts and thunderstorms. Reports the peak wind gust within the next hour and the next 12 hours, whether a thunderstorm is expected within the next hour, when the next thunderstorm is expected across the whole forecast horizon, and the peak CAPE over the next 12 hours as a diagnostic. Deliberately reports no severity verdict — what counts as dangerous is the caller's judgement. An hour counts as a thunderstorm when GeoSphere's weather symbol for it is a thunderstorm, or when the C-LAEF ensemble's 90th percentiles reach 1000 J/kg CAPE and 0.1 mm precipitation (only from an ensemble run less than 12 h old). Each thunderstorm answer names its signal: symbol, ensemble or both. CAPE does not decide anything on its own. High-resolution GeoSphere AROME data (1 km) and the C-LAEF ensemble. Serves Austria and the Alpine region only; a point outside that grid returns an out-of-coverage notice. The thunderstorm scan covers the forecast horizon, nominally ~60 h but shorter after publication lag or when a run is stale or truncated. A "none in the next N h" answer names the horizon it actually covered; it is not an all-clear beyond that. "Thunderstorm expected" is unknown only when no forecast hour falls in its window. Horizons round up to whole hours: the "next hour" window covers the hour already under way plus the next one. A thunderstorm timestamp at or before the current time means one is already in progress. Args: latitude: Decimal latitude (e.g. 48.2208 for Vienna). Geocode city names to coordinates yourself. longitude: Decimal longitude (e.g. 16.3738 for Vienna).
