Background
• CONsolidated Community Emissions Processing Tool - CONCEPT.
• PostgreSQL, Perl, PostGIS. Some fortran for M6, Nonroad, CMAQ
• Build with a community in mind: easy to read/modify and customize QA.
• Now operational and will be part of LADCO/MWRPO SIP.

Models in CONCEPTAnd what makes them different
• Industrial Point- advanced temporal
• Area- advanced temporal
• Nonroad- integrated NONROAD, day specific meteorology
• Biogenics – BEIS2/BEIS3/MEGAN
• NH3- Processed based model (NAS recommendation)
• Onroad- Complex temporal, Link Based

If you want a modeling system that needs extensive and flexible QA
and is foundation community model
![Page 5: Recent Developments in the Community Emissions Model CONCEPT 5 th Annual CMAS Model User Conference Tuesday October 17, 2006 Mark Janssen LADCO.](https://reader034.fdocuments.us/reader034/viewer/2022051214/56649e455503460f94b398d3/html5/thumbnails/5.jpg)
Onroad Motor Vehicle• Link based onroad model with embeded version
of mobile6. • T3 – Conversion tool reads many travel demand
models makes them usable by CONCEPT• Handle very complex temporal(month, day,
hour, ) by road and vehicle type for VMT, Speed, Mix.
• Adjust speed based on volume after temporalization
• Flexible speed, temperature bins for accelerated M6 Processing
• Toxics being added by USEPA

EGU Temporal based on CEM• Gold Standard in Emissions, Direct
measurement
• Use the Hourly CEM Data to derive more represenative EGU inventories.
• Automated tool other users can use not a one-off analysis. Create complex NIF3.0
• Need profiles because actual hourly not usable in future years.
![Page 11: Recent Developments in the Community Emissions Model CONCEPT 5 th Annual CMAS Model User Conference Tuesday October 17, 2006 Mark Janssen LADCO.](https://reader034.fdocuments.us/reader034/viewer/2022051214/56649e455503460f94b398d3/html5/thumbnails/11.jpg)
EGU Temporal based on CEMContinued…
• Build hourly weekday, Saturday, Sunday for each month.
• Why Not use: Large Data, What is Typical, Matching CEM to the NEI.
• CEM Analysis tool will ship with CONCEPT v.66
• Use CONCEPT’s temporal processor that can use the complex temporal NIF allows.

• Total emissions (TPD) from: – EMS/BIOME (BEIS3)

models
• Less Isoprene using MEGAN model

Agricultural Ammonia
• Processed based NH3 model based on recommendations from National Academy of Science.
• Model runs every farm and requires complex input data like N content of feed, barn color.

Ammonia Emission Rate from Swine Housing (two days in February)

NH3-Next Steps
• Poultry Housing Model science not complete
• May years of validation work because there are limited field measurements.
• Model too slow to be operational( months to run 7 days nationally.
• Speed up the model. C, perl, fortran• PC single facility version so people doing
validation studies can test tool.
![Page 24: Recent Developments in the Community Emissions Model CONCEPT 5 th Annual CMAS Model User Conference Tuesday October 17, 2006 Mark Janssen LADCO.](https://reader034.fdocuments.us/reader034/viewer/2022051214/56649e455503460f94b398d3/html5/thumbnails/24.jpg)
Performance Problems
• We have a model that works, but is slow• Link based networks, biogenics, nh3 model. • Projects underway to improve them. • Example is CAMX/CMAQ writer that used to
take 12 hours, now runs in 67 seconds. • Opinion: Better to have a transparent model that
is slow than a fast black box. Can fix speed problems where needed.
• If speed was a primary concern we would all be running CAMX not CMAQ.
