At assimilation station
Discussion points:
- Algal Cyanobacteria and Algal Green: the truth is non zero even in the winter. Is this realistic? This is the result of modelling the error as additive to the input variable. Perhaps modelling the error as multiplicative?
At validation stations
Discussion points:
- For all the four assimilated parameters, accuracy at the downstream locations is improved. The accuracy of Phosphate estimate at the assimilation station is however deteriorated. Perhaps this is due to the interaction between Phosphate and the other assimilated parameters? Suggestion: perform a twin experiment where only Phosphate is assimilated.
- Water temperature is affected by the noise although it is not included in the state vector definition. Assimilating the four water quality parameters doesn't help improve the accuracy of water temperature estimates.
