      The forests of northern New England were nearing peak autumn color on   
      October 6, 2022. That’s the same date that the Moderate Resolution   
      Imaging Spectroradiometer (MODIS) on board NASA’s Terra satellite   
      acquired a true-color image of a stunning flush of orange painting the   
      high elevations between Montreal, Canada to Massachusetts, United   
      States and from the Adirondacks to the White Mountains.   
      
      Each autumn, the changing colors of deciduous leaves paint North   
      America with glorious shades of yellows, oranges, reds, and browns. The   
      transition starts in the north and in high elevations as early as   
      mid-September then sweeps downslope and southward until it is completed   
      in mid-November. The changing of leaf color in temperate forests   
      involves several causes and reactions, but the dominant factors are   
      sunlight and heat.   
      
      As daylight begins to shorten in late summer and autumn, tree and plant   
      leaves produce less chlorophyll, the green pigment that harvests   
      sunlight for plants to convert water and carbon dioxide into sugars.   
      The subsidence of chlorophyll allows other colorful chemical compounds   
      contained in the leaves, such as carotenoids and flavonoids, to become   
      visible.   
      
      The leaves of different deciduous tree species (the type that drop   
      their leaves in the fall) contain a variable mix of pigments, and this   
      means that they produce different colors in autumn. Oaks generally turn   
      red, brown, or russet; hickories become golden bronze; aspen and   
      yellow-poplar turn golden. Maples differ by species. Red maple turns   
      brilliant scarlet; sugar maple, orange-red; and black maple, yellow.   
      Leaves of some trees, such as elms, simply become brown. New England’s   
      forests contain an abundance of deciduous trees and also are rich in   
      coniferous trees, which do not drop their needles in the fall, but   
      remain green year-round.
