§ The online (adaptive) estimation of
inflation parameter alone does
not work without estimating the observational errors.
§ Estimating both of the observational errors and the inflation
parameter simultaneously our approach
works well on both the Lorenz-96 and the SPEEDY
global model. It can also be applied to
other ensemble based Kalman filters.
§
§ SPEEDY experiments show our approach can simultaneously estimate observational errors for
different instruments.
§ Current work shows our method also works
in the presence of random model errors.
