There is a link to another site on the InterNet for the entry itself: Photochemical Smog - Natural and artificially emitted hydrocarbons in the presence of oxides of nitrogen undergo photochemical reactions which produce a cloud of toxic chemicals including ozone and a variety of caustic agents. This process is powered by sunlight and some of the products, such as ozone, reach a peak soon after photon flux from the sun reaches a maximum around midday. The thermal inversions often associated with some cities can lead to a dangerous buildup of smog in urban areas.

Security and Privacy Notice The Atmospheric Chemistry Program (ACP) is a Global Change Research program sponsored by the Environmental Sciences Division of the U.S. Department of Energy (DOE) The overall objective of the ACP is to provide DOE with advanced information on the atmospheric environment that is required for long-range energy planning. The research is carried out primarily at four DOE laboratories and approximately twelve universities and non-DOE labs. The thrusts of this research are on regional and continental chemistry and fate of tropospheric air pollutants, extracontinental and global chemistry and fate of tropospheric air pollutants, and aerosol genesis. Laboratory studies emphasize rate and equilibrium processes. Field studies are conducted with aircraft and surface measurements on reaction chemistry, advective influences on the chemical composition of chemistry, and air-surface exchange processes. Modeling efforts address both chemistry and dynamics on regional and global scales.

15. F.Sherwood Rowland - Autobiography Rowland shared the 1995 Nobel Prize in Chemistry for work in atmospheric chemistry. http://www.nobel.se/chemistry/laureates/1995/rowland-autobio.html

Our home was filled with books, and all of us were avid readers. My reading at that time ran toward naval history, which was complemented with realistic scale-models and simulated naval battles using an elaborate mathematical system for rating each warship and the effects of combat on them. During my sophomore year in high school, my math teacher, who also coached tennis and basketball, encouraged me to take up tennis - which led me onto the varsity tennis team for my junior and senior years, and into a full decade of intense athletic competition. As a senior, I played on the varsity basketball team. After graduation from high school in 1943, almost all of my male classmates immediately entered the military services. However, because I was still well under the compulsory draft age of 18, I enrolled at Ohio Wesleyan and attended the university year-round for the next two years. During these war years, only 30 or 40 civilian males were on campus, plus about 200 naval officer trainees and 1,000 women. With so few men available, I played on the University basketball and baseball teams, and wrote much of the sports page for the University newspaper. My accelerated academic schedule made me eligible for my final year of university in June, 1945, as I approached my 18th birthday. However, with the fighting in the Pacific and the continuing military draft, I enlisted in a Navy program to train radar operators. The Pacific war ended while I was still in basic training near Chicago, and I served the next year in several midwestern Naval Separation Centers, as the 10,000,000 Americans who had preceded me into the military were returned to civilian life. A major amount of this Navy time was devoted to competitive athletics for the Navy base teams, and I emerged after 14 months as a non commissioned officer with a rating of Specialist (Athletics) 3rd class. My first real opportunity to see the rest of the United States came when I was transferred to San Pedro, California for discharge from the Navy.
