Kalman filtering

---

SNOW-43 is a state-space version of the Snow Accumulation and Ablation model (Hydro-17) with the option of performing Kalman filtering updating.
The state-space formulation and Kalman filtering implementation are described in Hydro-43.
The Kalman filter accounts for the relative uncertainties of observed and simulated water equivalent values in a procedure that optimally updates the model simulated states using areal estimates of snow water equivalent based on observations.
