What would you find in the METAR report for Jackson Hole that indicates visibility conditions?

• A. 10SM
• B. CLR
• C. M20/M32
• D. A3007

Answer: (A)

The visibility conditions in a METAR report are indicated using a specific format that expresses the distance in statute miles. In the case of Jackson Hole, the notation "10SM" clearly indicates that the visibility is 10 statute miles. This is a standard representation in METAR reports, where "SM" stands for statute miles and the number preceding it denotes the percentage of visibility. In contrast, other choices do not provide visibility information. "CLR" refers to clear skies, which relates to cloud cover rather than visibility distance. "M20/M32" indicates a temperature and dew point in Celsius, while "A3007" gives the altimeter setting in inches of mercury. These elements are essential for understanding weather conditions but do not pertain to measuring visibility. Thus, "10SM" is the correct choice as it directly communicates the visibility level reported in the METAR.
