What is indicated by "SCT000" in a METAR report?

• A. Less than five zero scattered
• B. Clouds scattered at zero feet
• C. No significant weather observed
• D. Visibility clouds scattered

Answer: (A)

In a METAR report, "SCT000" specifically indicates that there are scattered clouds at an altitude of zero feet above ground level. This notation demonstrates that, while there are some clouds present, they do not give any height above the ground, suggesting that they are very low, possibly indicating mist or fog rather than actual cloud cover at a defined altitude. The presence of "SCT" in the report signifies that the clouds are scattered, which typically refers to a significant number of clouds observed within a certain range, but not enough to completely cover the sky. The "000" indicates their height is at ground level, suggesting a potential visibility limitation due to low cloud or mist conditions. In this context, the other options do not accurately fit what "SCT000" represents. The correct interpretation highlights the significance of specific cloud observations in understanding weather conditions relevant for flight operations and safety.
