As a global center for petrochemical manufacturing, Houston, Texas, experiences some of the worst air quality in the country, according to the U.S. Environmental Protection Agency. Evidence suggests that air pollution disproportionately affects low-income, non-white and Hispanic.

The use of the Space Shuttle to measure tropospheric trace species is examined. Factors which affect the measurement of tropospheric trace species are discussed. The Academy of Sciences report categorized the trace species into levels: first-level gases include water vapor, O3, CO, and CH4, and the second-level gases are N2O, NO2, NH3, SO2, chlorofluoromethanes, and : Joel S.

The authors describe how to develop and validate methods for determining tropospheric trace constituents from satellite data, to encourage the use. Sounding the Troposphere from Space: A New Era for Atmospheric Chemistry [Borrell, Peter, Borrell, Patricia May, Burrows, John P.

The future of tropospheric chemistry measurements Central to future research achievements is the synthesis of atmospheric chemistry processes that transcend traditional atmospheric spatial and temporal scales.

Through the use of a geostationary platform, the tropospheric chemistry community can learn much from a spaceborne scientific mission. A model for the photochemistry of the global troposphere constrained by observed concentrations of H 2 O, O 3, CO, CH 4, NO, NO 2, and HNO 3 is presented.

Data for NO and NO 2 are insufficient to define the global distribution of these gases but are nonetheless useful in limiting several of the more uncertain parameters of the model. Concentrations of OH, HO 2, H 2 O 2, NO, NO 2, NO 3, N 2 O 5 Cited by: Exclusive offer for individuals only.

Research in atmospheric chemistry helps to build a predictive capability for future environmental conditions that can indicate likely impacts to society of various.

Introduction [2] Changes in trace gas emissions caused by human activity have a profound impact on ozone (O 3) in both the stratosphere and the past few years, a number of chemistry-climate models (CCMs) have been developed to understand and quantify the influence of the key chemical and physical processes that determine ozone concentrations.

For these reasons we recommend that major research efforts in the Global Tropospheric Chemistry Program be undertaken with the following specific scientific objectives: 1.

To evaluate biological sources of chemical sub- stances in the troposphere. Tropospheric ozone, one of the most important green-house gases and one of the most essential components of photochemical smog, has been monitored from space by different retrieval techniques.

Global Atmospheric-Biospheric Chemistry (Prinn, b) greatly improved the understanding of the chemical and biological processes that determine the composition of Earths atmosphere.

Atmospheric Chemistry in a Changing World (Brasseur et al.) is considered the first international assessment of global tropospheric chemistry.

In Chapters 1 through 4 (Part A, we propose and justify a coordinated program of tropospheric chemistry re- search whose scope extends to global scales.

Atmospheric chemistry has been the focus of much research activity in recent years, and there is now heightened public awareness of the environmental issues in which it plays a part.

In a clear, readable style, this important book looks at the insights and interpretations afforded by the research, and places in context the exciting, dramatic Reviews: 6. Prompted by an increasing awareness of the influence of human activity on the chemistry of the global troposphere, a panel was formed to (1) assess the requirement for a global study of the chemistry of the troposphere; (2) develop a scientific strategy for a comprehensive plan taking into account the existing and projected programs of the government; (3) assess the requirements of a global.

Blake, D. Blake, in Encyclopedia of Atmospheric Sciences, Introduction. The troposphere, the region of the Earth's atmosphere in which we live and breath, is composed of many different kinds of components range from the abundant two-atom molecules O 2 and N 2, to larger and more reactive chemicals, which include vast numbers of different volatile organic compounds (VOCs).

To answer basic science questions about man's influence on the Earth's troposphere and how to protect it, a National Research Council (NRC) panel has proposed a longterm international research program to study global tropospheric chemistry.

The panel estimates that initial funding of 20 million per year will be required, increasing yearly for the program's minimum year ing. P GLOBAL TROPOSPHERIC EXPERIMENT: TROPOSPHERIC CHEMISTRY DATA SPANNING 18 YEARS AVAILABLE FROM THE NASA LANGLEY ATMOSPHERIC SCIENCES DATA CENTER. James M.

Hoell, Jr. SAIC, Hampton, VA. The NASA Global Tropospheric Experiment (GTE) was initiated in the early s and consists of an ongoing series of global airborne measurement. Remote Sensing of Tropospheric Pollution from Space We review the progress of tropospheric trace gas observations and address the need for additional measurement capabilities as recommended by the National Academy of Science (NAS, ).

Tropospheric measurements from current and earlier instruments show pollution in the Northern Hemisphere as a result of fossil fuel burning and a strong. Simulated tropospheric ozone concentrations at remote locations, which agreed well with observations in the previous model version, are not affected much by the chemistry of higher hydrocarbons.

However, ozone formation in the polluted boundary layer is significantly enhanced, resulting in a more realistic simulation of surface ozone in regions.
