  1. aWe eliminated the value at 35.6°N due to its large error bar
  2. bWe excluded an outlier at 44.5°N
  3. cValues with large error bars at 13.5° and 14.5°N as well as subject to topographic effect at 10.7°N were not included
  4. dA value at 11.3°N was not adopted due to its large estimated error
