Select core lake and catchment models
General Discussion
We will select a lake model and a catchment model. Including new models in the framework should be easy.
Catchment Models
PIHM has water quality, but we will write our own carbon cycle model that will include appropriate processes and modeling granularity. PIHM also has GIS facilities.
Need to consider calibration in the coming months: hydrodynamic model calibration with LTER site, also the hydrodynamic and hydrologic model.
Lake Models
GLM is developed by ecological community, as open source software. It has taken some time to develop, and it is being tested by 15-20 different sites. A paper on this is forthcoming.
Other models are IPH-ECO, Delft3d.
The community has 3 different ecological simulation packages. Each has a lot of uncertainty, to address this people do ensemble modeling with all three. In limnology, uncertainty has not been used much so ensemble modeling is new.
If GLM becomes open source (being developed by Australian researchers) then we can use it.
Craig Snortheim, a student at Wisconsin, has implemented carbon cycling in R, could be a code base for our work.
With GLM we can create internal boundary conditions for the lake, so it should be easy to couple with PIHM.
If GLM does not become open source we can still use it, we do have the source code.
Model Overview
The models that we are considering include:
