Some are capable of generating an observation every minute?

• A. METAR
• B. OMO
• C. LOCAL
• D. Automated Meteorological Observing Systems (AMOS)

Answer: (D)

Observations can be produced at different frequencies depending on the system. The Automated Meteorological Observing System is built for continuous automated data collection and transmission, often delivering observations on a one-minute cadence. That capability makes it the system that can generate an observation every minute. METARs, by contrast, are standard aviation weather reports issued on a regular, typically hourly schedule, with occasional special reports when conditions change, not a guaranteed minute-by-minute stream. The other options aren’t established as minute-by-minute observation platforms in this context. So the system that can provide an observation every minute is the Automated Meteorological Observing System.
