Which option best describes the T group in METAR?

• A. Temperature and dew point to the nearest tenth of a degree Celsius
• B. Temperature and dew point to the nearest whole degree
• C. Wind direction and speed
• D. Visibility and cloud cover

Answer: (B)

The T group is the part of a METAR that conveys temperature and dew point with extra precision. It provides both values to the tenths place of a degree Celsius, which means you get a decimal part rather than just whole numbers. This added precision helps give a more accurate sense of atmospheric conditions for forecasting and data assimilation. The other weather elements like wind, visibility, or cloud cover are reported in different parts of the METAR, not in this group, so describing temperature and dew point with tenth-degree precision is the correct interpretation.
