Among this array are a few groups of wavelengths that allow scientists to track subtle changes in <a href=\"https:\/\/svs.gsfc.nasa.gov\/5548\/\" rel=\"noopener\">leaf pigments<\/a> key to fall foliage displays, including anthocyanins (reds), carotenoids (yellows and oranges), and chlorophylls (greens).<\/p>\n<p class=\"wp-block-paragraph\">NASA scientists can track fall color by measuring how much red, orange, and yellow forests show compared with green. Tracking the ratio over time reveals where leaves are changing and when color peaks. The maps above show vegetation \u201credness\u201d from September 29 to October 4 (left) and October 5 to 11 (right). Areas shown in green have values near 1, meaning the satellite detects about as much red as green, and most leaves have not yet turned. Areas shown in light yellow and red have higher values, indicating progressively more red pigment relative to green. <\/p>\n<p class=\"wp-block-paragraph\">The satellite detected particularly high levels of redness in parts of northern and eastern Russia, northern Alaska, and northern Canada from September 29  to October 4. In New England and upstate New York, redness began to fade during the week of October 5 to 11, even as it spread across much of the Midwest and the Mid-Atlantic. (Not all the yellows and reds on the maps represent fall colors. Crops in some agricultural areas, for instance, show high anthocyanin levels as they age and after they are harvested. Also, in some regions, clouds produce what appear to be gaps in the vegetation.)<\/p>\n<h2 class=\"wp-block-heading\">Seeing Red in Vermont<\/h2>\n<p class=\"wp-block-paragraph\">Many of the reddest areas\u2014such as the <a href=\"https:\/\/science.nasa.gov\/earth\/earth-observatory\/autumn-in-the-adirondacks-150482\/\" rel=\"noopener\">Adirondacks<\/a> in New York, the Green Mountains in Vermont, and the White Mountains in New Hampshire\u2014have large numbers of sugar maples <em>(Acer saccharum)<\/em> and red maples (<em>Acer rubrum)<\/em>, deciduous trees that turn a brilliant shade of crimson in the fall.
