Which elements are pressure, temperature, dew point, and wind?

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

Answer: (D)

In weather observations, data are classified by whether they come from instruments (objective) or require human judgment (subjective). Pressure, temperature, dew point, and wind are objective elements because they are determined by instruments and expressed as precise numerical values. They reflect actual atmospheric conditions at the observation moment and are not based on a observer’s interpretation or opinion. While these measurements can be captured by automated systems, the defining trait is their instrument-based, numerical nature. The other categories don’t fit as well because subjective elements rely on human judgment for things like cloud cover or weather phenomena, and automated observations or AMOS elements refer to how the data are collected or what system is used, rather than the inherent nature of the measurements themselves.
