    Washington DC: Due to global warming and melting ice caps it is inevitable that rising sea levels within the next years will displace millions of people living along our nation's coast. The NASA-led study is known as DISCOVER-AQ, and is being conducted July 14 to August 12 in Denver. The research began in with air quality measuring conducted in the Baltimore-Washington, DC, area followed by a field campaign in California’s San Joaquin Valley and Houston in

    Using a nationwide network of monitoring sites, EPA has developed ambient air quality trends for particle pollution, also called Particulate Matter (PM). PM describes fine inhalable particles, with diameters that are generally micrometers and smaller. Under the Clean Air Act, EPA sets and reviews national air quality standards for PM.

Neither Baltimore nor Washington Cluster 1 data (cloudy, cool days) showed any statistically significant trends in ozone concentrations. The Baltimore Cluster 2 and Washington Cluster 4 data (3% high ozone days) measured increases in ozone concentrations followed by later DC book, but these trends were confounded by a 60% drop in median precipitation for those clusters during Cited by: 9.

Data mining exercises were used to describe long-term ambient ozone concentrations in Baltimore and Washington based on meteorological conditions as well as upwind and previous day concentrations. Ozone production occurs mainly during the summer months and is influenced by a variety of meteorological parameters.

Fifteen years of daily ozone measurements (May-September) were Cited by: 9. The focus of this study is to provide a long-term (i.e.

years, ) climatology of the seasonal, annual, intra-annual and inter-annual variations of ozone and surface meteorology in the Baltimore-Washington region, which is located at the southern end of the Clean Air Act-mandated Northeast Ozone Transport Region (OTR).

This book discusses how scientific information can be used to develop more effective regulations to control ozone. Rethinking the Ozone Problem in Urban and Regional Air Pollution discusses: The latest data and analysis on how tropospheric ozone is formed. How. Baltimore-Washington Region.

Employment and job projections need to be addressed by both Baltimore and Washington, DC planning agencies because the projected labor pool in the combined regions cannot possibly fill the projected number of new jobs.

Both agencies project new jobs that far outstrip the number of individuals in the labor. The Environmental Protection Agency (EPA) designates surface ozone as DC book harmful pollutant and has recently reduced the ozone daily maximum 8-h average (MDA8) exceedance threshold from 75 to 70 ppbv across the United States, making the job for air quality (AQ) forecasters more challenging (Cooper et al.

; EPA ).To help AQ forecasters with the prediction of ozone MDA8, various tools have. Results. Relationships between the daily 1 hour maximum [O 3] ([O 3] max) and T max from June 1-October 31 (reflecting the “ozone season” in California) are separated by air basin and decade (Fig.

1).The plateau of concentrations below K suggests a background [O 3] of 30–40 K, [O 3] max increases approximately linearly with temperature with a slope (m O3. Ozone production efficiency (OPE) represents the number of ozone (O 3) molecules produced per molecule of NO x (NO 2 +NO), before NO x is converted to a sink or reservoir species.

Observations from NASA's July DISCOVER-AQ (D-AQ) campaign in the Baltimore-Washington region are used to quantify OPE, which is compared to output from the Community Multiscale Air.

Provides real-time air pollution data in an understandable, visual format, information about the public health and environmental effects of air pollution, information about ways in which the public can protect their health, and actions they can take to reduce pollution.

In contrast to the rapidly warming Arctic, sea surface temperature (SST) averaged over the Southern Ocean (SO) has exhibited a multidecadal cooling trend from the beginning of the satellite record in (Fan et al. ; Armour and Bitz ) (although this trend may have reversed since late ; Meehl et al. ).During the same period, there have also been significant changes in the.

Ozone is an important air pollutant that affects lung function. In the U.S., the EPA has reduced the allowable O3 concentrations several times over the last few decades. This puts greater emphasis on understanding the interannual variability and the contributions to surface O3 from all sources.

We have examined O3 data from 11 rural CASTNET sites in the western US for the period. The book begins with an introduction to the basic atmospheric chemistry and the history of discovery of chemicals in the atmosphere, and then moves on to a discussion of the evolution of the earth's atmosphere, and the structure and composition of the present-day atmosphere.

Tropospheric ozone is a secondary air pollutant that has been recognized as a serious public health risk [U.S.

Whether you are an engineer or business professional looking to advance your career, or an educator in search of creative and effective ways to engage students in STEM programs, we have you covered.While HFCs are only weak ozone-depleting substances, they are, like CFCs and HCFCs, strong greenhouse gases.

If production trends continue, projections show that, bythe amount of global warming by all HFCs could be as large as 20 percent that of carbon dioxide. Work is also underway to analyze HFC impacts on surface climate.2 Methods.

We use the Comprehensive Air‐quality Model with Extensions (CAMx) version to simulate trace gas mixing ratios in the eastern United States for July ; the model domain is shown in Figure S1 in the supporting information. Many previous studies have used CAMx to simulate ozone with reasonable fidelity [Emery et al., ; Dolwick et al., ; Koo et al., ].
