WebIonosphere Scintillation Service (ISM) ISM provides global nowcast S4 and σ Φ maps based on numerous GNSS receivers (1 Hz) and a few high rate GNSS receivers (50 Hz). Furthermore, it provides forecast of S4 and σ Φ maps up to 6 hours ahead. The forecasts are most reliant near the equator and less reliant in polar regions.
