Lake Ecosystem Modelling Working GroupTimeline
• Introduce New Model Framework
GLEON 11Nanjing, ChinaOctober 2010
• Distribute GLEONites Model Profile Questionnaire• Generate Common Model Dataset(s)
GLEON 13Lake Sunapee, NHOctober 2011
GLEON 12Ramot, IsraelApril 2011
Take-Off•Conduct Interactive Workshops for Developers and Users
•Develop Core-Group (and Network) Model
GLEON 10Torres, BrazilMay 2010
• Develop Mission Statement• Provide Model Overview• Determine Data Requirements of Models
• Start Multi-Model Comparisons (Lake Kinneret and Possibly Lake Rotoehu) - Temporal Scale: Hourly vs. Daily input- Spatial Scale: 1D vs. 3D- Conceptual Models (Check Possibility of Using PROTECH, PCLake, DYRESM-CAEDYM, CE-QUAL-W2 for Same lake – e.g., Lake Rotoehu)• Outline Generic Parameter Database in Google Spreadsheet to define model content and vocabulary

Status and Ongoing Work (1)Action Items
from G12Status
Multi-Model Comparisons - Lake Kinneret (Israel)
•Gideon Gal and Sandy Ng are currently working on a 1D vs 3D model comparison for Lake Kinneret .•The work is ongoing.•If necessary (and practical), Gideon or Sandy may contact members of the working group to contribute.
•A study on DYRESM-CAEDYM vs. GLM-FABM for Lake Kinneret will soon be underway (Louise Bruce, Gideon Gal, Matthew Hipsey).
Multi-Model Comparisons - Lake Engelsholm (Denmark)
•Dennis Trolle has DYRESM-CAEDYM and PCLake running for Lake Engelsholm (a relatively shallow, biomanipulated Danish lake).•Alex Elliott will apply PROTECH to this lake.
•Application of GLM-FABM is planned (Dennis Trolle and Matthew Hipsey). •Application of CE-QUAL-W2 is also desirable but not planned.
•A model comparison paper focusing on structural uncertainty and the effects of model complexity on predictive capability is planned for 2012.
Multi-Model Comparisons - Diagenesis Models
•Dan Paraska (Ph.D. student with Matthew Hipsey, UWA) has a review paper in prep.
Online Parameter Database •Google spreadsheet configuration has recently been updated•Available via AEMON site (https://sites.google.com/site/aquaticmodelling/Resources)•Continue Work at GLEON 13

Other Action Items Relevance to GLEON
Status
Development of Open Source Models •Alpha-version is completed.•UWA group (Matthew Hipsey) has DO-Si-NO3-NH4-PO4-POC/DOC-PON/DON-POP/DOP dynamics and multi-phytoplankton implemented with FABM and GLM Model. •Beta-version will be released before December 2011.
•Karsten Bolding (Developer of GETM, a 3D hydrodynamics model) is currently working part-time at Aarhus University (with Dennis Trolle) and helping with open source model development.
Status and Ongoing Work (3)
Other Action Items Relevant to GLEON
Status
Development of Open Source Models(Continued)
•A full 3 year Ph.D. scholarship will soon be offered jointly by Aarhus University and Southern Danish University (starting early 2012). The Ph.D. student is to be based in Denmark and work on Lake Fure (the deepest lake in Denmark), and apply and further develop the FABM.•If interested, please contact Dennis Trolle for further information.
•Community-model concept paper has been submitted (currently under review) with 24 authors including 9 GLEON authors.
•Hands-on workshop for core model developers is planned to run within the next 12 months .•It will be announced on the AEMON site https://sites.google.com/site/aquaticmodelling/

MATLAB / CSV 0D N/A Generic FABM driver -Under development
GLMGeneral Lake Model
1D Lagrangian layered grid
Ice coverCurrently daily time-step onlySimple to use
GOTMGeneral Ocean Turbulence Model
1D Fixed grid
Multiple turbulence models in library
Assumes hypothetical column, so not good for small-medium lakes
GETMGeneral Estuarine Transport Model
2D/3DRegular or curvilinear in horizontal and sigma in vertical
Uses GOTM turbulence library
Open source, but complex to use
TUFLOW-FV Flood and Coastal Simulation

Next StepsGLEON 13
•Continue developing parameter database with definitions and ranges from literature.
•Define new ecological metrics to validate models (and develop scripts/models that can easily calculate/derive these from model outputs and observations).
•Work with the climate and physics group on modelling the effects of climate change on many lakes across several gradients (e.g. latitude, area, depth, color).
•Explore predictive models that recreate high-frequency signals (temp, DO, pigment fluorescence) measured by many GLEON lakes.
•Develop means of sharing open source models with GLEON membership.
NOTE: Hands-on exercises using new open source model(s) should be ready for G14…
News on model releases, developments ,and test cases, etc. will be announced here.
