How often does SAROPS weather data update?

How often does SAROPS weather data update?

• A. Hourly
• B. From one to four times daily
• C. Once a week
• D. Once daily at 00 UTC

Answer: (B)

Weather data in SAROPS is refreshed as new forecast model runs are issued, not on a fixed hourly timetable. Because meteorological models deploy updates at different times and some data streams aren’t available for every cycle, the system can ingest new data anywhere from once to four times per day. A typical cadence is about every six hours, which yields up to four updates daily, but on some days there may be only one update if data availability limits it. This variability is why the best answer describes updates occurring from one to four times daily. The other options imply a strict or overly sparse schedule that doesn’t reflect how SAROPS ingests METOC data.
