IFS Atmospheric probabilities 0.1°

GribStream Code: ifsenfoprob0p1

IFS probabilities: 00 and 12 UTC; 12h steps; daily atmospheric events use overlapping 24h windows
00 / 12 UTC · +12…360h: 12h · 24h: +24…360h This coverage reference was generated from for the ifsenfoprob0p1 page; available variables may differ.

Event probabilities in percent (0–100): precipitation and gust thresholds over 24 hours, plus instantaneous temperature anomalies at 850 hPa.

00 and 12 UTC cycles. Instantaneous probabilities every 12 hours from +12 to +360h. Daily events use 24-hour windows ending at +24, +36, …, +360h; adjacent windows overlap by 12 hours.

The source record begins on 20 October 2026 at 12 UTC. Each statistic has its own dataset with no member dimension. Query the exact selectors below with runs or timeseries.

Daily events use info="24h" and the timestamp marks the window’s end. Instantaneous events use empty info. Anomaly thresholds are ±1, ±1.5 and ±2 standard deviations, not absolute temperature thresholds.
