According to the World Meteorological Organization, Air Temperature should be measured

Question

BlackTom AI · Accepted Answer

The question asks about where the World Meteorological Organization recommends measuring air temperature.
Option 1: 'Near the Ground' – Measuring too close to the soil or obstacles often leads to distortion from heat absorption by surfaces or radiation; this location is not standard for official air temperature measurements.
Option 2: 'In the Sun' – Direct solar radiation heats the instrument and the surrounding air, causing readings that are higher than true air temperature; this setup is unsuitable for accurate measurements.
Option 3: 'In a closed, unventilated room' – A closed room can have stagnant air, poor ventilation, and heat sources that skew readings; it does not represent ambient atmospheric conditions.
Option 4: '1.5-2 meters above the ground' – This height is the conventional reference height for air temperature measurements because it minimizes ground heat effects, radiative warming from surfaces, and localized buoyant flows, providing a more representative air temperature of the environment.
Overall, the reasoning for selecting the preferred measurement height centers on minimizing biases from ground influence, sun exposure, and ventilation, aligning with standard meteorological practice for temperature observations.
