A -- ENHANCEMENT OF THE SPARSE MATRIX OPERATOR KERNEL EMISSION (SMOKE) MODELING SYSTEM FOR GENERALIZED CHEMICAL SPECIFICATION (MORPHECULE MECHANISM) AND INTEGRATION INTO THE MODELS-3 FRAMEWORK TO SUPPORT VOC REACTIVITY ASSESSMENTS SOL UPA813 DUE 052898 POC Contact Pamela Ricks, 919/541-2312/Contracting Officer, Julio Lopez 919/541-4474 E-MAIL: Click here to contact the Contract Specialist via e-mail., ricks.pamela@epamail.epa.gov.. The U.S. Environmental Protection Agency intends to award a Simplified Acquisition to Microelectronics Center of North Carolina for the enhancement of the Sparse Matrix Operator Kernel Emission (SMOKE) Modeling System for generalized chemical specification (Morphecule Mechanism) and integration into the Models-3 Framework to support Volatile Organic Compound (VOC) reactivity assessments. Basic functionality shall include the following: (1) SMOKE within Models-3 shall have the ability to access and use data objects defined by the user in the Models-3 Science Manager (such as grid definition, chemical mechanism specification, etc.); (2) SMOKE within Models-3 shall have the ability to successfully pass and receive the emission files in I/O API netCDF expected by the CMAQ and its preprocessors to and from the Models-3 framework, sharing data with key modules including CMAQ, the Emission Chemistry Input Processor (ECIP), Meteorology Chemistry Input Processor (MCIP), as well as the Models-3 visualization tools; (3) SMOKE shall have the ability to output the same basic files in I/O API netCDF format currently produced by the Models-3 emission processor (point, area, biogenic, and mobile source files), with the same basic options (e.g., user-defined point source categorization, use of imported CEM data, use of imported Canadian or Mexican emission inventory data); (4) SMOKE within Models-3 shall have the ability to rapidly manipulate temporally, spatially, or by emission category, a large number of chemical species from each of many emission sources; (5) the number of species shall be limited only by species information available from system default specification profile files, from the user via emission inventory data, or available source-category or source-specific chemical specification profiles; (6) the processor must be able to group species according to user-defined specifications of the needs of a chemical mechanism; and (7) the species groupings of commonly-used chemical mechanisms now used in Models-3 (Carbon Bond 4 and RADM 2.0) must be retained. The Environmental Protection Agency believes that Microelectronics Center of North Carolina of Research Triangle Park, NC is the only source capable of satisfying the requirements stated above. Microelectronics Center of North Carolina developed the SMOKE Modeling System and is the sole owner of the computer code. The period of performance is expected to be from date of award through February 15, 1999. Interested parties who can meet the above specifications may submit qualification statements no later that 15 days after the date of this publication to the U.S. EPA, Attn: Pamela G. Ricks (MD-33) Contracts Management Division, Research Triangle Park, NC 27711. No telephonic requests will be honored. (0132)
