What do SLP and the T group represent on a METAR?

• A. SLP stands for Sea Level Pressure; T group represents the current temperature and dew point, expressed to the nearest tenth of a degree Celsius
• B. SLP stands for Standard Level Pressure; T group represents the altitude
• C. SLP stands for Sea Level Pressure; T group represents wind speed
• D. SLP stands for Sea Level Pressure; T group indicates cloud cover

Answer: (A)

In METARs, the SLP value is Sea Level Pressure—it's the atmospheric pressure adjusted to sea level, reported to give a consistent reference across stations. The T group, on the other hand, encodes the actual air temperature and the dew point, both in Celsius and with precision to the nearest tenth of a degree. This pairing lets you quickly gauge moisture in the air: a small difference between temperature and dew point means higher humidity, while a larger gap indicates drier air. The SLP and T group aren’t about wind speed or cloud cover, which are conveyed by other parts of the report, nor is SLP about standard level pressure or altitude.
