LOTOS-EUROS uses Ensemble Kalman filtering for data assimilation.
LOTOS-EUROS has used Ensemble Kalman filtering for data assimilation. Data assimilation of satellite NO2 and O3 ground concentrations is applied in the operational forecast. Also for PM10 and AOD data assimilation has been used. In addition, Observing System Simulation Experiments have been performed for the design of future satellite missions. Recent developments include the use of 4d-var for passive tracers.
