Regional Acid Deposition Model predic- 

 tions of nitric acid over the eastern U.S. 



curriculum development for environmental education for 

 grades 9-12 as well as university undergraduate and 

 graduate programs. 



BRHR: Broadening the User Community 



EPA will develop and evaluate methods and materials 

 for training Federal, state, and industrial users of 

 advanced environmental assessment tools. 



It has initiated a program to train analysts who support 

 environmental decision making in advanced computing 

 technology. The scope of this program ranges from 

 making it as easy as possible to use the models to 

 developing interactive software for on-line training. 



EPA also sponsors fellowships, graduate student pro- 

 grams, and high school computational science programs 

 to develop interdisciplinary skills required for air and 

 water quality modeling. 



Major FY 1993 Activities and Accomplishments 

 and FY 1994 Plans 



Multipollutant Air Quality IVIanagement 



Working with the North Carolina Supercomputing Center 

 and several universities, EPA has initiated a Grand 

 Challenge air quality management project in which a 

 user friendly, multipollutant, multiscale air quality model- 

 ing system is being developed for modeling research, 

 evaluation, and regulatory assessment. 



The first prototype of the system will address regional 

 and urban-scale ozone and regional acid deposition 

 issues using generic scalable algorithms for key physical 

 and chemical processes, and advanced technology for 

 data management, interprocess communications, analy- 

 ses, and visualization. 



EPA has also begun to evaluate the performance of both 

 low and high end massively parallel computers on ai.' -" - 

 sphehc chemistry and transport algorithms and mo .-ou- 

 lar modeling codes critical in environmental assessrinent. 

 The Regional Oxidant Model has been ported to a 'i.OOO 

 processor MasPar for benchmarking. Molecular 

 mechanics and dynamics algorithms are also being eval-
