Handling Model and Calibration Errors In Inversions Method 1 Define H = H t + H e Determine H e from multiple runs of different models Increase measurement error by H e x t Method 2 As in Method 1, but simply run the filter for an ensemble of different H matrices from different models and observation vectors ( y 0 ) with different calibrations chosen to have equal probability (Monte Carlo) Method 3 Use the state-space evolution equation ( x(t)=M(t)x(t-1) + n(t)) and compute Q=E(nn T ) from multiple model H values.
