Accurate representation of precipitation input into hydrology models is therefore critical. The purpose of this research is to determine if NEXRAD data can be used as input into hydrological models as part of a MIMS prototype study taking place in the NEUSE River Basin of eastern North Carolina.

Report to Congress Pagan, J.; McKelvey, L.; Jul. 2000; 398p Report No.(s): PB2001-102245; EPA/453/R-99/007; No Copyright; Avail: CASI; A17, Hardcopy; A04, Microfiche On July 19, 1999, the authors published a notice in the Federal Register entitled ’National Air Toxic Program: The Integrated Urban Air Strategy’ (Strategy) that outlined the U.S. Environmental Protection Agency’s (EPA’s) plans for addressing cumulative health risks in urban areas. The Strategy presented the authors’ plan for future actions to reduce emissions of air toxics and improve our understanding of the health risks posed by toxics in urban areas. Section 112(k) of the Clean Air Act (CAA) requires the EPA Administrator to submit two Reports to Congress on actions taken under the CAA that reduce the risk to public health posed by the release of hazardous air pollutants (HAP) from area sources. This Report to Congress (Report), originally due in 1998, was prepared to meet the first part of that requirement. In addition, it expands on much of the information provided in the Strategy, such as the methodology for developing the emissions inventory, identifying the 33 urban HAP and identifying the area source categories that will be subject to regulation. Furthermore, this Report summarizes existing information on risk assessments that have been conducted in various urban areas. These studies were performed by EPA and various States over the last several years. Taking into consideration the uncertainties and limitations of each study, these assessments provide useful information on the potential nature and magnitude of exposures and health risks in urban areas. Finally, this Report also provides a very detailed discussion of 13 research needs to address in achieving the goals of the Strategy. These needs were identified in the following areas: exposure assessment, health effects, dose-response assessment, risk assessment, risk characterization and risk management. In addition, Chapter 6 of this Report provides a summary of ongoing EPA activities to address those needs.

Overall, national air quality levels measured at thousands of monitoring stations across the country have shown improvement over the past 20 years for all six principal pollutants. Despite this progress, over 150 million tons of air pollution were released into the air in 1999 in the USA, and approximately 62 million people lived in counties where monitored data showed unhealthy air for one or more of the six principal pollutants.

C.; 2000; 20p; In English Report No.(s): PB2001-101545; EPA/600/A-00/107; No Copyright; Avail: National Technical Information Service (NTIS) National and international concern about the health effects and continued use of mercury (Hg) as well as other metals has defined the need for estimates of the long term risks to ecosystem and human health from Hg released from human activities. The atmosphere is one of the mechanisms by which Hg is transported throughout the environment. This report will provide an overview of what efforts are being undertaken within the U.S. and Canada to improve our understanding of the processes governing 200
the atmospheric concentrations of mercury, the temporal and spatial variability of atmospheric mercury, and the sources and sinks of atmospheric mercury.

This algorithm is based on a least-squares minimization, and uses Micro shield calculations of dose rates as a function of altitude over a patch of contaminated ground. The algorithm is successful in that it correctly identifies regions of high and low contamination, which would permit a commander to identify areas to avoid, or paths to follow through a non-uniformly contaminated region. However, the contamination pattern predicted by this algorithm is not a high-fidelity facsimile of the actual distribution. The reason for this deficiency is likely that the problem of calculating ground-level contamination patterns from airborne measurements is inherently underdetermined, and evidence is presented to this effect. These results demonstrate clearly the utility of airborne survey for military purposes, and a method of analyzing the data from such a platform.

In this paper, we use satellite data to investigate the long-term variability of airborne Asian dust as well as the daily variation of the dust aerosol distribution. by combining the Total Ozone Mapping Spectrometer (TOMS) aerosol index with National Centers for Environmental Prediction (NCEP) wind data, our analysis shows a strong correlation between the generation of dust storms in the region and the passage of springtime weather fronts. This is consistent with earlier studies performed by other researchers. According to both the Nimbus-7 and Earth-Probe TOMS data the Takla Makan desert, the Gobi desert, and the and region of Inner Mongolia are major sources of the eastward-flowing airborne Asian dust. Heavily populated areas in eastern China (e.g., Beijing) are often on the primary path of the dust storms originating in these desert regions. The increasing desertification north of the Beijing region has served to exacerbate problems stemming from these storms. The time series derived from 20 years of TOMS aerosol index data shows the first significant satellite evidence of the atmospheric effect of increasing desertification, indicating that the amount of dust blown eastward has increased strongly during the past few years including the year 2000.
