FluxNet Land surface modelling meeting
University of Edinburgh, School of GeoSciences, Crew Bldg, Room 304
4-6 June 2008
Objective
To resolve the details of a coordinated approach to calibrating Land surface models from FluxNet data using data assimilation (DA).
Outputs
- A workplan for coordinating international resources for an LSM calibration exercise using FluxNet data
- A publication demonstrating the utility of FluxNet data for model calibration
Key questions
- How many models should be calibrated? One or many?
- What calibration approach should be used? Do different approaches have different strengths and weaknesses?
- How should observation and model error be determined and accounted for?
- How do we deal with observational or model bias?
- Is the objective to retrieve a full quantification of land surface exchange for the observed period (state estimation), or to generate a forecast model (parameter estimation)?
- How do we address the initial condition problem?
- How do we detect and address model flaws?
- How many and which towers should be used?
- How should the flux data be processed?
- What ancillary data (including EO) can and should be used?
