What does a "T" preceding the temperature value in a METAR report indicate?

• A. Taken at the surface
• B. Temperature adjustment
• C. Trace of weather observed
• D. Temperature in tenths of degrees

Answer: (D)

A "T" preceding the temperature value in a METAR report signifies that the temperature is reported in tenths of degrees Celsius. This is important for accurate weather reporting, as it provides a more precise measurement of temperature than whole degrees. For instance, if you see "T0234," it means the temperature is 2.34 degrees Celsius. This level of detail can be crucial for various aviation and meteorological applications where small changes in temperature can have significant impacts. The other options relate to different concepts in METAR reporting, such as surface measurement, weather observations, or temperature adjustments, but do not apply to the specific indication of tenths of degrees, which is what the "T" directly signifies.
