Which elements may be missing in a weather report?

• A. Sky Condition (Ceiling) / Temperature and Altimeter only if RTMA is used.
• B. Visibility and Winds
• C. Sky Condition (Ceiling) only
• D. Temperature and Altimeter always included

Answer: (A)

Weather reports don’t always include every field; some elements depend on the data product being used. The sky condition, which tells you about the ceiling, can be omitted in certain reports if cloud data isn’t available or isn’t provided by that product. Temperature and altimeter settings are not universally included unless you’re using RTMA (Real-Time Mesoscale Analysis); in RTMA-enabled outputs those fields appear, but in other products they may be absent. So the elements that may be missing are the sky condition (ceiling) and the temperature/altimeter, with the latter present only when RTMA is used. The other options are less accurate because winds and visibility are typically included, and temperature and altimeter are not guaranteed to be present in all reports.
