    ChemMatters: Special Issue on NASA's EOS Aura Mission (Oct. 2003)

    Get PDF
    This is the third in a series of four ChemMatters issues devoted to NASA’s Earth Observing System (EOS) Aura mission and it focuses on the chemistry of the mission. ChemMatters is designed and published for teachers to use as a supplement to their first year high school chemistry course, and as a resource for other high school science teachers. Article titles are: Whose Air Is It Anyway (global circulation of the atmosphere), Alien Atmospheres (atmospheres of other planets), Clouds (how clouds form, and cloud research), Life in a Greenhouse (how the greenhouse effect works and how people study it), Chemistry in the Sunlight (about formation of the ozone we breathe), Beefing Up Atmospheric Models (how modeling helps us understand the atmosphere), and Nobel Prize Winner: Sherwood Rowland (interview). The issue also includes a challenge asking students to determine which activities on a list would be possible on a planet with no atmosphere; and an activity, Cloud in a Bottle. A 62-page teacher's guide accompanies the issue and provides additional information on articles, follow-up hands-on activities, classroom demonstrations, and additional resources.

    Global Climate Change and Illinois

    Get PDF
    The climate of Illinois is greatly affected by the state's position in the middle of the North American continent, the third largest land mass on earth. The mountains in the western part of the continent are a formidable barrier to the prevailing westerly winds that circle the globe. But flat lands in the central United States permit air movement across the Midwest from both the frozen lakes of northern Canada and the warm Gulf of Mexico. The shape, size, and surface topography of North America set the stage for Illinois' climate.published or submitted for publicationis peer reviewe

    Earth's mysterious atmosphere. ATLAS 1: Teachers guide with activities

    Get PDF
    One of our mission's primary goals is to better understand the physics and chemistry of our atmosphere, the thin envelope of air that provides for human life and shields us from the harshness of space. The Space Shuttle Atlantis will carry the ATLAS 1 science instruments 296 km above Earth, so that they can look down into and through the various layers of the atmosphere. Five solar radiometers will precisely measure the amount of energy the Sun injects into Earth's environment. The chemistry at different altitudes will be measured very accurately by five other instruments called spectrometers. Much of our time in the cockpit of Atlantis will be devoted to two very exciting instruments that measure the auroras and the atmosphere's electrical characteristics. Finally, our ultraviolet telescope will probe the secrets of fascinating celestial objects. This Teacher's Guide is designed as a detective story to help you appreciate some of the many questions currently studied by scientists around the world. Many complex factors affect our atmosphere today, possibly even changing the course of global climate. All of us who live on Earth must recognize that we play an ever-growing role in causing some of these changes. We must solve this great atmospheric mystery if we are to understand all these changes and know what to do about them

    Falsification Of The Atmospheric CO2 Greenhouse Effects Within The Frame Of Physics

    Full text link
    The atmospheric greenhouse effect, an idea that many authors trace back to the traditional works of Fourier (1824), Tyndall (1861), and Arrhenius (1896), and which is still supported in global climatology, essentially describes a fictitious mechanism, in which a planetary atmosphere acts as a heat pump driven by an environment that is radiatively interacting with but radiatively equilibrated to the atmospheric system. According to the second law of thermodynamics such a planetary machine can never exist. Nevertheless, in almost all texts of global climatology and in a widespread secondary literature it is taken for granted that such mechanism is real and stands on a firm scientific foundation. In this paper the popular conjecture is analyzed and the underlying physical principles are clarified. By showing that (a) there are no common physical laws between the warming phenomenon in glass houses and the fictitious atmospheric greenhouse effects, (b) there are no calculations to determine an average surface temperature of a planet, (c) the frequently mentioned difference of 33 degrees Celsius is a meaningless number calculated wrongly, (d) the formulas of cavity radiation are used inappropriately, (e) the assumption of a radiative balance is unphysical, (f) thermal conductivity and friction must not be set to zero, the atmospheric greenhouse conjecture is falsified.Comment: 115 pages, 32 figures, 13 tables (some typos corrected
