The screening version of ISC3 is [[List of atmospheric dispersion models#Screening models|SCREEN3]].<br /> <br /> Very recently, the status of ISC3 as a [[List of atmospheric dispersion models#Preferred and recommended models|Preferred/Recommended Model]] of the [[United States Environmental Protection Agency|US Environmental Protection Agency]] has been withdrawn, but it can still be used as an alternative to the Preferred/Recommended models in regulatory applications with case-by-case justification to the reviewing authority.<br /> <br /> == Input data ==<br /> <br /> ISC short term version required two sets of data: source data and hourly averaged [[meteorological]] data:<br /> <br /> === Source data ===<br /> <br /> * Dimensions of the source<br /> * [[Air pollution|Emission]] discharge rate<br /> * Release height of the emission source<br /> <br /> === Meteorological data ===<br /> <br /> * Ambient temperature, K<br /> * Wind direction<br /> * Wind speed, m/s<br /> * Atmospheric [[Air pollution dispersion terminology|stability classes]] (A through F, entered as 1 through 6)<br /> * [[Air pollution dispersion terminology|Urban and rural]] mixing height, m<br /> <br /> == See also ==<br /> <br /> *[[Bibliography of atmospheric dispersion modeling]]<br /> *[[Atmospheric dispersion modeling]]<br /> *[[List of atmospheric dispersion models]]<br /> <br /> ==Further reading==<br /> <br /> For those who are unfamiliar with air pollution dispersion modelling and would like to learn more about the subject, it is suggested that either one of the following books be read:<br /> <br /> *{{cite book | author=Turner, D.B. | title=Workbook of atmospheric dispersion estimates: an introduction to dispersion modeling | edition=2nd | publisher=CRC Press | year=1994 | isbn=1-56670-023-X | url-access=registration | url=https://archive.org/details/workbookofatmosp0000turn }} [https://web.archive.org/web/20071105075907/http://www.crcpress.com/shopping_cart/products/product_detail.asp?sku=L1023&amp;parent_id=&amp;pc= www.crcpress.com]<br /> *{{cite book | author=Beychok, M.R. | title=[[Fundamentals Of Stack Gas Dispersion]]| edition=4th| publisher=self-published | year=2005 | isbn=0-9644588-0-2}} [http://www.air-dispersion.com www.air-dispersion.com]<br /> <br /> ==External links==<br /> *[http://www.epa.gov/scram001/userg/regmod/isc3v1.pdf ISC3 User&#039;s Guide, Volume I]<br /> *[http://www.epa.gov/scram001/userg/regmod/isc3v2.pdf ISC3 User&#039;s Guide, Volume II]<br /> *[http://www.epa.gov/scram001/guidance/met/mmgrma.pdf Meteorological Monitoring Guidance for Regulatory Modeling Applications]<br /> &lt;br&gt;<br /> {{Atmospheric, Oceanographic and Climate Models}}<br /> <br /> [[Category:Atmospheric dispersion modeling]]</div>
