What is the MIMS Software Suite?
• Software to support composing, configuring, applying, and evaluating complex systems of models
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
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
SMOKE in MIMS Framework
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
Differences from Original Models-3 Framework
• 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
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
Special Features for Models-3
• Simple I/O API file viewer• Grid editor• Chemical mechanism editor• Spatial allocator
– Computes surrogates and intersections of coverages
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– Documentation is a year out-of-date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
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
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
