Elements such as pressure, temperature, dew point, and wind; automated and augmented observations use a fixed location and time-averaging technique.

• A. Subjective Elements
• B. Objective Elements
• C. AMOS Observations
• D. Local Observations

Answer: (B)

These are objective elements. They’re values measured directly by instruments (pressure, temperature, dew point, wind) and reported as numeric data. Automated and augmented observations use fixed sensor locations and time-averaging to produce consistent, repeatable measurements, which is a hallmark of objective data. Subjective elements rely on human interpretation, such as describing cloud cover or weather phenomena, rather than instrument readings. AMOS Observations describe the automated system itself, not the category of the elements, and Local Observations refer to data from a local site, not to how the data are classified.
