PUBLIC EDUCATION In 1996, the Department of Meteorology moved into the newly contructed 4th wing of the Computer and Space Sciences Building. On Dedication Day of this new wing, the two group occupants - Department of Meteorology and Office of Information Technology, organized a public open house to show off earth system science and information technology. Overall design and organization was led by Owen Thompson [Meteorology], Jennifer Fajman [OIT], Daniel (Chip) Denman [OIT], and Ellen Borkowski [OIT]. The open house event was so well received by the visiting public that the team decided to sponsor public open house events each year. The event was dubbed Explore planet UM , and became one of the key centerpieces of the MARYLAND DAY - explore our world campus open house event, commencing in year 2000. The year 2000 event brought some 8000 visitors into the 4-floor activity area of planet UM through its six hour duration. This web site presents an extensive summary of the various activities conducted by the Department of Meteorology during the annual open house events from 1996-2002. Each activity appearing below has active weblinks to further details. DIRECTIONS TO THE LAUNCH CENTER

    There is more material about this subject under heading middle and upper atmosphere.
    The ozone research was started at the Finnish Meteorological Institute (FMI) in 1989. At present, the research group consists of 11 employees.
    The ozone research is based on observations, data on stratospheric dynamics and models of stratospheric chemistry and dynamics. Special emphasis is put on Arctic and Antarctic latitudes. At Antarctica, Finnish-Argentine ozone sounding and total ozone observations have been performed since 1988.
    The research group has been responsible for establishing UV monitoring network in Finland. In this work, special attention has been paid on the calibration and maintenance of the instruments. The UV research is based on measurements of UV radiation, radiative transfer models and several ancillary measurements of importance for radiative transfer.

    Meteorological Research
    The basic goal of the meteorological research is to understand why the atmosphere behaves as observed. Another purpose of the research is to create necessary qualifications and tools for the institute's service activities, which benefit both the society and economy of the country. Internationality is one of the characteristics of our research. Here, as in other projects, we cooperate with other Nordic and European partners. The academic meteorological education in Finland is given by the Meteorological Department of the Helsinki University, which is the other center of the meteorological research in Finland.
    The research unit has its premises in the centre of Helsinki. There are about 40 persons out of which 80% have acquired an academic education. 14 researchers have PhD degree. Roughly one quarter of the funding comes from external sources where the EU based source is a substantial one.
    The research is concentrated on current topics described below. In respect of ozone and climate change research see also headings Middle and upper atmosphere and Climate change

    Meteorology Data and Activity
    Background:
    Ground-level ozone pollution is mainly a daytime problem during summer months because sunlight plays a primary role in its formation. Nitrogen oxides and hydrocarbons are known as the chief "precursors" of ozone. These compounds react in the presence of sunlight to produce ozone. The sources of these precursor pollutants include cars, trucks, power plants and factories, or wherever natural gas, gasoline, diesel fuel, kerosene, and oil are combusted. These gaseous compounds mix like a thin soup in the atmosphere, and when they interact with sunlight, ozone is formed. Large industrial areas and cities with heavy summer traffic are the main contributors to ozone formation. When temperatures are high and the mixing of air currents is limited, ozone can accumulate to unhealthful levels. The United States Environmental Protection Agency has set the National Ambient Air Quality Standard for ozone at 0.12 parts per million (ppm). Ozone concentrations of 0.125 ppm (125 in parts per billion) or above are considered an exceedance of this standard because of mathematical rounding. The Monitoring Operations Division has more ozone information.

    Chapman's meteorological studies and his impact on meteorology are more than enough to secure him a position of lasting influence in this field, even though his major interests are concentrated on other branches of terrestrial and space physics. Along with many others he felt that the word "meteorology" is an inappropriate name for this field, and in a letter published in 1946 entitled "A Plea for the Abolition of Meteorology" he suggested that it be renamed "aeronomy." As this suggestion was not accepted by meteorologists, he proposed later that the term "aeronomy" be adopted for the science of that part of the upper atmosphere "where dissociation and ionization become important." It is impossible to separate Chapman's contributions to the fields of meteorology and aeronomy, since they overlap, but three of his accomplishments of particular interest to modern meteorologists may be singled out for special mention. These are his work on diffusion in the earth's atmosphere, his studies of the photochemistry of atmospheric oxygen as it applies to ozone, and his work on atmospheric tides and oscillations. Among Chapman's many papers applying diffusion theory to stellar and planetary atmospheres, special mention must be made of his and Kendall's theory of the origin of noctilucent clouds, published in 1965. This theory, based on a systematic investigation of the upward diffusion of water vapor and the downward diffusion of meteoric dust, attributes the appearance of these clouds to the simultaneous occurrence of a descent of the turbopause to the mesopause, a low mesopause temperature, and the presence of moist air below the mesopause. While acceptance of their theory will depend on the observation of the three required conditions when noctilucent clouds are present and absent, the theoretical discussion of the diffusion and convection and of their effect on the formation of noctilucent clouds will remain a guide for future studies.

    ABSTRACT
    , and NO x ) and meteorological variables (wind direction and speed, temperature, humidity, pressure, and solar radiation) were examined. Several identifiable weather patterns were found to produce ozone events (high monitored maximum ozone levels lasting one or two days), and ozone episodes (high monitored maximum ozone levels lasting three days or more). However, no other clearly limiting condition to ozone formation was identified although NOx, temperature, humidity and solar radiation vary predictably with ozone variations. Locally, ozone dissociation by NO emitted from mobile sources is an important factor mitigating high ozone levels.
    INTRODUCTION The City of Evansville, located on the Ohio River in Vanderburgh County Indiana, is the urban hub of southwestern Indiana. The Evansville Metropolitan Statistical Area (MSA), which also includes the City and County of Henderson Kentucky, and the Indiana counties of Posey and Warrick, is home to approximately 300,000 people. Around the main cities of Evansville and Henderson, one finds manufacturing industries and suburban developments dispersed among agricultural lands.
    Vanderburgh County was designated as a marginal ozone nonattainment area in 1992 In recent years, area ozone monitors have recorded several exceedances but no violations of the one-hour ozone standard, however, as of 1999, seven out of the area eight area monitors have recorded violations of the new eight-hour standard.

    Summary of the Chapter
    This chapter introduces the student to the study of climatology and meteorology. The chapter begins with an examination of the composition and structure of the atmosphere. According to temperature change with altitude, seven different layers can be identified in the atmosphere. The lowest layer, the troposphere, extends from the surface to a height of 11 kilometers. This layer contains the majority of the atmosphere's mass and is the location for most of the Earth's weather. Characteristics of the other six layers are described in detail. The gases nitrogen and oxygen together make up about 99 % of the volume of the dry atmosphere. The remaining 1 % is comprised of a number different gases of which ozone, carbon dioxide, nitrous oxide, and methane are the most important to life on the Earth. Ozone is concentrated in a layer that extends from 15 to 55 kilometers above the Earth's surface. Ozone is important to life because it absorbs harmful ultraviolet radiation from the sun. Recent investigations of the ozone layer have discovered areas of severe thinning located primarily at the South Pole. Researchers have determined that this thinning is caused by the emission of the artificially produced chemical chlorofluorocarbon into our atmosphere.
