Surface Process Modeling: Applying the CSDMS Modeling Tool
GEOG5700: Course Scope
Irina OvereemCSDMS-Community Surface Dynamics Modeling System
University of Colorado, Boulder, CO
Outline
• Scope Discussion• Survey of Your Expectations
• Introduction to CSDMS• Concept Survey
• Example of Climate-Stratigraphy Model Interactions
• Introduction to Coupled Modeling
CSDMS =Community Surface Dynamics Modeling System
Promotes development and use of numerical modeling in earth surface dynamics research.
~ 450 members, (int.)nationally, academic, industry, government
• Model, Data and Educational Repositories• Access to supercomputer system, called Beach• Development of an easy-to-use Coupling Tool (CMT)
What is CSDMS?
Model Repository
• Models have meta-data
• Models are open-source
• Models are freely downloadable from CSDMS HPCC
Model Repository
We developed a database for the Model Repository, now users:1.Provide Metadata in new user-friendly questionnaire.2.Submit Model and Associated Test & Validation files to CSDMS
Three classes of Models
Model Repository
CHILD
GC2D
TOPOFLOW
Sept 2010,
93 terrestrial models,57 Coastal models,27 Marine models,50 Hydrology models,4 Carbonate models.
Objective: distribute model simulations, educational presentations, reports, publications, short course material.
EKT Repository in 2010:
- 3 modeling textbooks + all codes available through repository.
- 4 modeling courses; more general to detailed processes.
- 20 modeling labs; coastal-geological, terrestrial and sediment transport.
- > 40 educational movies (real-world and model animations)
Educational Repository
Educational Animations
o Model animations to explain surface-dynamics processes. Every animation has a short description, and explanation of theory, and references.o Fit into the data-base structure in Wiki.
CEM: Coastal Evolution of Wave-dominated Coast (Ashton & Murray).
Educational Animations
Basic model experiments, stepping up in complexity.Associated theory and algorithms are key for learning processes as well as model sensitivity.
SEDFLUX: Basic Plume SEDFLUX: High Switch Frequency
CMT Tool
The CSDMS Modeling Tool allows you to couple and run CSDMS components on the CSDMS supercomputer in a user-friendly environment.
A component can be any unit that encapsulates some useful functionality, most often a model or function.
CMT Tool• Input data needs to be prepared;
standardizing formats (NetCDF)
• Output data can be processed with VisIT,
• Lab 2 dedicated to NetCDFand VisIT
Temperature, depth volume
Coupled Models
Ability to drag in components; run them together
4 course labs will be dedicated to running models
