Title:
Smog Over New York
Explanation:
What is not pretty about the above picture [ http://visibleearth…]? In a word: smog [ http://www.epa.gov/…]. In 2000 October the orbiting Space Shuttle [ http://antwrp.gsfc.…] Discovery [ http://science.ksc.…] photographed upstate New York [ http://www.state.ny…] just at sunset. Visible is golden sunlight reflecting [ http://antwrp.gsfc.…] from two of the Great Lakes [ http://www.great-la…] (Erie and Ontario), and several of the Finger Lakes [ http://www.fingerla…]. Between the clouds at the top and ground at the bottom, however, is a trapped layer [ http://daphne.palom…] of smog. Smog [ http://www.on.ec.gc…] is mostly ozone [ http://earth.rice.e…] but may contain small amounts of volatile organic compounds [ http://www.epa.gov/…]. As opposed to "good smog [ http://www.epa.gov/…]" in the upper atmosphere, "bad smog" near the ground is created mostly [ http://www.epa.gov/…] by humans. In the upper atmosphere, ozone [ http://www.epa.gov/…] reflects back harmful ultraviolet radiation [ http://imagers.gsfc…], but when it occurs near the ground, it can be inhaled. Smog continues to be studied with an eye for how it develops and how it affects human health [ http://www.epa.gov/…].
