SMOKE (the
Sparse Matrix Operator Kernel Emissions) was used by IMAQS to provide primary emissions inputs for the AQMs,
mainly CMAQ. The
SMOKE has been improved with
the support of the U.S. EPA
for use with the Models-3 Air Quality
Modeling System to
allow fast and efficient emissions
processing utilizing
high-performance-computing (HPC) sparse-matrix algorithms (MCNC). It supports
various data input formats such as Inventory Data
Analyzer (IDA), Emissions Modeling System (EMS)
and AMS/AFS formats used in EPS2. The current version of SMOKE needs additional pretreatement steps to
process hourly point emissions in AFS format and hourly link-based mobile emissions
from MOBILE6.
EPS2 is our alternative emissionsapprocessing model for CAMx simulations. EPS2 consists of a series of FORTRAN modules
for data importing, chemical speciation, temporal and spatial allocation of
emissions inventory used for photochemical modeling (U.S. EPA, 1992). One of the most significant differences
between EPS2 and SMOKE is emissions inventory input formats and the importing modules.
Area
and nonroad mobile source emissions were
prepared in AMS (AIRS Area and Mobile Source) data format for PREAM
(PREprocessor for Area and Mobil sources),
one of EI importing modules in EPS2. For the
emission inventory including link-based
MOBILE6 outputs for the HGA 8 Counties,
a
FORTRAN code is used to convert the file format from
MOBILE6 to LBASE (Link-BASEd emissions
processor). PREPNT
(PREprocessor for PoiNT source emissions) is used to import hourly and daily average point source data in AIRS
Facility Subsystem (AFS) data
format.
