Transcript and Presenter's Notes

Title: Models-3


1
Models-3
  • Adel Hanna
  • Carolina Environmental Program
  • University of North Carolina at Chapel Hill

2
Regulatory or Policy User
  • Need to identify source of a problem,
    contributing factors, and methods of controlling
    or alleviating pollutant emissions
  • Need to understand the relative effectiveness of
    different controls and potential ramifications of
    proposed strategies

3
Science User
  • Seek to understand the physical-chemical system,
    how pollutants are produced, what processes are
    most important, and pollutant interact
  • Non trivial problem especially with processes
    that are complex and non linear
  • Evaluation (how well the model is representing
    the real world)

4
Models-3 Concepts
  • One Atmosphere
  • Description of the atmospheric System
  • Multi-scale
  • Multi-pollutant
  • One Modeling System
  • Flexible and expandable
  • Modular
  • Analysis tools and Data handling
  • One Community
  • Open Source
  • Multi-user
  • Platform for multiple contributions

5
Models-3 Modeling Components
  • Three Main Components
  • Sparse Matrix Operator Kernel Emissions (SMOKE)
  • Community Multi-scale Air Quality Model (CMAQ)
  • Meteorology Model (MM5, ETA, RAMS,..)

6
Models-3 a Vision to the Community Needs
  • Utilization of HPCC advances towards
    environmental modeling and decision making
  • Modular, extensible science implementation
  • Analysis and visualization Package
  • Flexible to address more comprehensive
    atmospheric pollution (PM, Visibility, Toxics)
  • Multi-scale (Urban, Regional, hemispheric)
  • Air Quality Forecast
  • Link to Human Exposure, Ecosystem

CMAS Technology Transfer
  • A vision of Community cooperation as means to
    improving our science understanding while sharing
    experiences in exercising models for regulatory
    purposes
  • From research to application to outreach, CMAS
    center is to advance the community modeling
    paradigm through the establishment of a
    centralized resource to serve the members of the
    environmental modeling community

11
CMAS
  • Serve as a bridge between various segments of the
    community
  • Foster the growth of the developer and user
    communities
  • Serve as a clearinghouse of information
  • Become a hub for education and training about
    modeling
  • Develop and market the value of CMAS in order to
    become self-sufficient

12
CMAS Functions
  • Outreach
  • Developing the user community
  • Promoting value
  • Establish and foster collaborations
  • Create Self Sufficiency
  • Application Support
  • User Support
  • Training
  • Consultation and model applications

13
CMAS Functions (Cont.)
  • Software Development
  • Plans for External Review, Tracking, and
    Documenting model versions
  • Maintaining model codes and Documentation
  • Model inputs and outputs
  • Research
  • Application Driven
  • Model testing, development and evaluation
  • Computational Research and development

14
Community Contribution
  • EPA role in supporting Models-3 and its Potential
    user Community
  • Help Desk, training facilities (first year)
  • Science development and CMAQ releases
  • Model Evaluation
  • CMAQ review
  • External Advisory Committee
  • Members of the community are developing and
    sharing new modules

15
CMAS 2003/04
  • Outreach
  • News letter Quarterly
  • Annual workshop
  • Participation in Conferences
  • Research
  • Proposal on leading topics
  • CMAQ Review
  • Applications
  • Training sessions CMAQ, SMOKE, MIMS
  • Advanced Training
  • Off site training
  • Software Development
  • Protocol for coding standards

16
Summary
  • More than 600 active users representing different
    sectors of the environmental community
  • More interactions and communications
  • International Correspondence (Atmosphere has no
    boundaries)
  • CMAQ and SMOKE are among the leading models being
    used for various modeling applications
  • Improvements and developments continue
