The Science Of It All
Network Radar 2 9 27 +
It all starts with photosynthesis. Leaves typically produce their vivid hues of green from spring through summer into early fall through the constant creation of Chlorophyll. As we all learned in 5th grade science, Chlorophyll is the key component in a plant's ability to turn sunlight into glucose, which in turn feeds the trees. Many millions of these Chlorophyll cells saturate the leaves, ultimately making them appear green to the eye.

Without the presence of Chlorophyll in the leaf, the bright golds, reds, yellows, and browns would be the natural colors seen year round.
The Changing Colors
Chlorophyll is not the only player in the fall leaf-color game. Present in other leaves and trees are the compounds known as Carotenoids and Anthocyanins. As the Fall days begin to get shorter and shorter, the production of Chlorophyll slows to a hault, eventually giving way to the ‘true’ color of the leaf.

Beta-CaroteneBeta-Carotene is one of the most common carotenoids present in most leaves. Strongly absorbing blue and green light, it reflects yellow and red light from the sun, giving leaves their orange hue.
Reds
AnthocyaninsUnlike the carotenoids, anthocyanin production increases dramatically with autumn. This protects the leaf, prolonging its life on the tree through the Autumn season, and also provides the beautiful red color to the leaf.
Yellows
FlavonolsFlavonols, a part of the flavonoid protein family, are always present in leaves, and also contribute to the yellow color of egg yolks. While always present in leaves, it’s not seen until the production of Chlorophyll begins to slow.

Why do leaves fall?
The beauty of nature is sometimes found in the profound ‘intelligence’ it exudes. Perennials, which includes trees, must protect themselves in order to get through the harsh, freezing temperatures of winter. If trees did not shed their leaves, their soft vegetation would certainly freeze during winter time, damaging and, no doubt, killing the tree.
In order to cope with the grueling winter temperatures, trees slowly close off the veins that carry water and nutrients to and from the leaves with a layer of new cells that form at the base of the leaf stem, protecting the limbs and body of the tree. Once the process of new cell creation is complete, water and nutrients no longer flow to and fro from the leaf - this enables the leaf to die and weaken at the stem, eventually falling gracefully to the ground.

What happens to the fallen leaves?
Bookends 12 7 9 – reference management and bibliography software. Earth, among other things, is fantastic at recycling. Whether through the water cycle, or the slow process of decomposing plants and trees back in to rich soil, the Earth wastes very little.
When leaves fall to the ground, they begin to break down and eventually create a rich humus on the forest floor that absorbs dew and rainfall. This nutrient rich ‘sponge’ acts as a continual source of nutrients and water for trees and plants, helping to promote life and plant health in the next spring season.
It is not difficult to conclude that while the falling of the leaves protects the trees through winter, it’s likely that trees would not survive as well without the rich layer of dead leaves through the warm spring and summer months. In this way, trees' natural cycle provides health and sustainability for itself year after year.

Range and Coverage of Radar Sites
The typical range of most radar products is 230 km from the radar site. However, mountains can block the lower sweeps of the radar beam in certain parts of the country. The Interactive Radar Map Tool provides map layers, which show the maximum distance (230 km), as well as maps derived from geospatial models, which determine areas where the mountains block the beam. The analysis, conducted by NOAA's Radar Operations Center, shows the availability of beam coverage at specified altitudes from the ground. The map tool includes layers at 4,000 (best coverage), 6,000 (better coverage), and 10,000 (fair coverage) feet.
Please contact NOAA's Radar Operations Center for more information on how the coverage products are calculated.
Station Selection
The map tool includes selection tools, which allow users to select individual or multiple sites and begin the ordering process for historical data in NCEI's Radar Data Archive.
