Research Triangle Park, North Carolina
Research Triangle Park (RTP) is the largest research park in the United States, occupying in North Carolina and hosting more than 300 companies and 65,000 workers. The facility is named for its location relative to the three surrounding cities of Raleigh, Durham, and Chapel Hill, or more properly, for the three major research universities in them: North Carolina State University, Duke University and University of North Carolina at Chapel Hill respectively. The Research Triangle region of North Carolina received its name as an extension of the name of the park. Aside from the three anchor cities, the park is also bounded by the communities of Morrisville and Cary. Approximately one fourth of the Park's territory lies in Wake County, but the majority of its land is in Durham County. Overview Research Triangle Park is one of the most prominent high-tech research and development parks in the United States. It was created in 1959 by state and local governments, nearby universities ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Pollution Organizations
The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth protects life on Earth by creating pressure allowing for liquid water to exist on the Earth's surface, absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation). By mole fraction (i.e., by number of molecules), dry air contains 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere. Air composition, temperature, and atmospheric pressure vary with altitude. Within the atmosphere, air suitable for use in photosynthesis by terrestrial plants and breathing of terrestrial animals is found only in E ...

UK Atmospheric Dispersion Modelling Liaison Committee
The Atmospheric Dispersion Modelling Liaison Committee (ADMLC) is composed of representatives from government departments, agencies (predominantly but not exclusively from the UK) and private consultancies. The ADMLC's main aim is to review current understanding of atmospheric dispersion and related phenomena for application primarily in the authorization or licensing of pollutant emissions to the atmosphere from industrial, commercial or institutional sites. The ADMLC is primarily concerned with atmospheric pollutant discharges from regulated emission sites and other fixed sources. Their review and study interests include routine discharges as well as accidental releases or releases cause by operational upsets. Their interests also include modelling dispersion at all scales from on-site short range (including dispersion modelling indoors) to long range distances. The ADMLC does not normally get involved with pollutant emissions from roadway traffic or other non-fixed sources. Nor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Met Office
The Meteorological Office, abbreviated as the Met Office, is the United Kingdom's national weather service. It is an executive agency and trading fund of the Department for Business, Energy and Industrial Strategy and is led by CEO Penelope Endersby, who took on the role as Chief Executive in December 2018 and is the first woman to do so. The Met Office makes meteorological predictions across all timescales from weather forecasts to climate change. History The Met Office was established on 1 August 1854 as a small department within the Board of Trade under Vice Admiral (Royal Navy), Vice Admiral Robert FitzRoy as a service to sailor, mariners. The loss of the passenger vessel, the Royal Charter (ship), ''Royal Charter'', and 459 lives off the coast of Anglesey in a violent storm in October 1859 led to the first gale warning service. FitzRoy established a network of 15 coastal stations from which visual gale warnings could be provided for ships at sea. The new electric tele ...

Accidental Release Source Terms
Accidental release source terms are the mathematical equations that quantify the flow rate at which accidental releases of liquid or gaseous pollutants into the ambient environment can occur at industrial facilities such as petroleum refineries, petrochemical plants, natural gas processing plants, oil and gas transportation pipelines, chemical plants, and many other industrial activities. Governmental regulations in many countries require that the probability of such accidental releases be analyzed and their quantitative impact upon the environment and human health be determined so that mitigating steps can be planned and implemented. There are a number of mathematical calculation methods for determining the flow rate at which gaseous and liquid pollutants might be released from various types of accidents. Such calculational methods are referred to as ''source terms'', and this article on accidental release source terms explains some of the calculation methods used for determining ...
