EPA's Multimedia Integrated Modeling System Software Suite: A Comprehensive Modeling Framework

This text introduces EPA's Multimedia Integrated Modeling System Software Suite, a powerful framework for composing, configuring, applying, and evaluating complex systems of models. It provides user interfaces to connect and interchange models seamlessly and supports repetitive tasks like modeling multiple locations and sensitivity studies. The suite aids in managing computations on multiple computers and offers data manipulation capabilities. Potential benefits for users include a GUI for running models, archiving configurations, automating work, and executing models on remote computers. The guiding principles focus on simplicity, future planning, customer needs, and generalization. Features include a graphical user interface, automation of repetitive tasks, and compatibility with various platforms. The suite also offers open-source development with responsive processes. Special features cater to Models-3 users and include tools like a grid editor and chemical mechanism editor. The text discusses the current status, future applications, and directions for development of the software suite.

  1. Introduction to EPA’s Multimedia Integrated Modeling System Software Suite:A New Framework for Models-3 Steve Fine (EPA/NOAA), Steve Howard (EPA/NOAA), Alison Eyth (MCNC), Dean Herington (UNC), Karl Castleton (PNNL) National Exposure Research Laboratory U.S. EPA Office of Research and Development

  2. What is the MIMS Software Suite? • Software to support composing, configuring, applying, and evaluating complex systems of models

  3. Current and Planned Features • User interface to support connecting and interchanging compatible models • Aid repetitive work, such as modeling multiple locations and sensitivity and uncertainty studies • Provide user interfaces for programs when desired, in most cases with no programming required • Manage computations on one or more computers • Data management and manipulation

  4. Potential Benefits for Models-3 Users • GUI for running CMAQ and SMOKE • Archive and share configurations for simulations • Automate repetitive work • Manage model executions on remote computers Might not benefit all Models-3 users

  5. SMOKE in MIMS Framework

  6. Guiding Principles • Make the common things easy; make the hard things possible. • Balance planning for the future with delivering value ASAP • Concentrate on what the customers need • Assume simplicity • Generalize as appropriate

  7. No data set catalog (yet) No GUI for compiling models Implemented for stand-alone users More general No cost to users Easier to install and use More reliable Compatible with more platforms Executes models on remote computers Looping Easier to extend Open source Development process is more responsive Differences from Original Models-3 Framework

  8. Current and Potential Future Applications • Models-3 • OAQPS’s Total Risk Integrated Methodology • Prototype urban drainage decision support system • Clean Air Markets Division’s deposition model • Coupled deposition-plant-soil model for deposition studies • Prototype optimization tool for air quality strategies

  9. Special Features for Models-3 • Simple I/O API file viewer • Grid editor • Chemical mechanism editor • Spatial allocator • Computes surrogates and intersections of coverages

  10. Status • Spatial allocator • On web • Memory consumption should be reduced • Will be discussing options with developer • Framework • Software is “beta” quality and is on web • Development continuing • Documentation is a year out-of-date • Documentation development should restart soon

  11. Future Directions • More robust long-duration simulations • Additional methods for accessing remote computers • Sensitivity and uncertainty tools • Model performance evaluation tools • CMAS support for application of MIMS to Models-3 • Continue to try to meet users’ needs

  12. Summary • EPA is developing MIMS to address a broad range of modeling needs • MIMS will support composition, configuration, application and evaluation of systems of models • The development approach and end result is very different from the old Models-3 framework http://www.epa.gov/asmdnerl/mims
