Figure 12 shows: METAR KLAX 121852Z 25004KT 6SM BR SCT007 SCT250 16/15 A2991. What do "SCT007 SCT250" and "BR" mean together?

Why: Sky condition is reported as amount-then-height, with cloud-base heights given as a three-digit number in hundreds of feet AGL — so SCT007 is a scattered layer at 700 feet and SCT250 is a scattered layer at 25,000 feet. BR is the weather contraction for mist, consistent with the report's 6SM visibility.

• Swaps the sky-coverage contractions — SCT (scattered, 3-4 oktas) is not a ceiling-forming amount like BKN (broken) or OVC (overcast), and it ignores BR, which is exactly what is restricting visibility to 6SM.
• Multiplies the three-digit height codes by 10,000 instead of 100, inflating 700 ft and 25,000 ft by two orders of magnitude; the codes are always read in hundreds of feet.
