Atmospheric Chemistry Discussion Questions How do atmospheric scientists view the atmosphere? What gases are pollutants in the atmosphere? The Atmosphere The atmospheric chemistry studies the chemical composition of the natural atmosphere, the way gases, liquids, and solids in the atmosphere interact with each other and with the earth's surface and associated biota, and how human activities may be changing the chemical and physical characteristics of the atmosphere . It is interesting to note that the 1995 Nobel Prize in Chemistry 1995 was awarded to the atmospheric scientists P. Crutzen , M. Molina and F. S. Rowland. How do atmospheric scientists view the atmosphere? For convenience of study, atmospheric scientists divide the atmosphere as if it consists of 4 layers. The division is mainly due to temperature variations as the altitude increases. The 4 layers according to the variation of temperature are. Ionosphere (Aurora) or Thermosphere Mesosphere Stratosphere Troposphere Above 100 km is the thermosphere and ionosphere where the temperature increases from 200 K at 100 km to 500 K at 300 km. The temperature goes even higher as the altitude increases. activity as the altitude decrease. In the outer space, most particles consist of single atoms, H, He, and O etc. At lower altitude (200 - 100 km), diatomic molecules N

Skip Navigation Atmospheric Chemistry Ozone is a form of oxygen which has both harmful and beneficial qualities. While each molecule of the normal oxygen we breathe is composed of two oxygen atoms, each ozone molecule has three. At ground level, ozone is considered a pollutant, formed in urban areas by reactions of volatile organic compounds (hydrocarbons) and oxides of nitrogen (NO x ). It is highly reactive and harmful to humans, animals, and plants. Because of its high reactivity and ability to harm microscopic organisms, ozone is used in some parts of the world to purify water. Ozone protects the lower atmosphere and Earth's surface by absorbing ultraviolet radiation in the stratosphere. Understandably, we are concerned with the decreases in stratospheric ozone concentrations. Antarctic Ozone Concentrations Ozone is a very rare gas with very small concentrations . In fact, if all the ozone present in the stratosphere were brought to Earth's surface at standard temperature and pressure (°C and 1 atm), it would comprise a layer less than 3 mm thick. Both human causes and natural events can influence the balance between the production and destruction of ozone. Since uv radiation is responsible for the production of ozone, there is a cycle of ozone amounts related to solar output. Manmade chemicals capable of reacting with ozone and

Atmospheric Chemistry Studies in the Oceanic Environment (ACSOE), which took place between 1995 and 2000, is a UK Natural Environment Research Council (NERC) Thematic Research Programme to investigate the chemistry of the lower atmosphere (0 - 12 km) over the oceans. The studies aimed to bring about a clearer understanding of natural processes in the remote marine atmosphere, and how these processes are affected by atmospheric pollution originating from the continents.

We may ordinarily take the atmosphere for granted and focus much more concern on the weather . This ocean of air, however, has profound consequences for life on Earth. The surface density of air is about 0.074 lb/ft (1.184 g/l) and surface pressure is about 14 lb/ft (1 atm). This mass of air presses downward at all times. At a higher altitude, however, both the pressure and the density of air decrease. This explains why passenger jets, which often fly near 40,000 ft (12,192 m) to take advantage of the thin or low-density air, require pressurized cabins. Without them, passengers would not be able to take in enough oxygen with each breath.

Areas of Research Atmospheric Dynamics Boundary Layer Research Climate Change Cloud and Aerosol Research ... Synoptic Meteorology Atmospheric Chemistry Faculty: Becky Alexander Dean Hegg Joel Thornton The atmosphere is chemically complex and evolving due to natural events, biological and anthropogenic activities; it has fundamental chemical links to the oceans, the solid earth and the biota. Anthropogenic perturbations such as land-use and industrial activities have profoundly modified the chemical composition of the troposphere and stratosphere, with potentially important consequences on future climate and living organisms. Examples of such changes include the formation of an ozone hole over Antarctica since the late 1970s, the observed trends in long-lived greenhouse gases, the change in the concentrations of tropospheric ozone and acidic deposition due to growing emissions of hydrocarbons, nitrogen oxides and sulfur dioxide in industrialized regions. Laboratory studies, field experiments and modeling activities by atmospheric chemists at the University of Washington are directed at determining chemical composition and chemical processes in the atmosphere and in turn their effects on the atmosphere, and on a larger scale the biogeochemistry of the earth. The laboratory and experimental research deals with trace gas measurements and physical, chemical and optical properties of particles. Global models of atmospheric chemistry and climate use these observations to improve their predictions of future changes in atmospheric composition, and also guide the development of analytical techniques and the logistics of large-scale field measurement programs.

Maps and gradesheets grade US counties from A to F on 10 measures of ambient concentration and on emissions of 11 pollutants. Each county then receives a composite grade based on these 21 individual measures. Air quality in neighboring counties also influences a county's map grade.

It shows hourly departures of today's temperatures from the normal diurnal cycle for U.S. and international airports, and 2-week running averages of those departures.
