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).

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.

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).

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).
