Sensitivity tests for an ensemble Kalman filter for aerosol assimilation
an ensemble Kalman filter aerosol assimilation
2010/8/16
We present sensitivity tests for a global aerosol assimilation system utilizing AERONET observations of AOT (aerosol optical thickness) and AAE (aerosol Ångström exponent). The assimilation...
Applying an ensemble Kalman filter to the assimilation of AERONET observations in a global aerosol transport model
Kalman filter assimilation AERONET observations global aerosol transport model
2010/3/16
We present a global aerosol assimilation system based on an Ensemble Kalman filter, which we believe leads to a significant improvement in aerosol fields. The ensemble allows realistic, spatially and ...
Parameter estimation in an atmospheric GCM using the Ensemble Kalman Filter
Parameter estimation atmospheric GCM Ensemble Kalman Filter
2009/11/9
We demonstrate the application of an efficient multivariate probabilistic parameter estimation method to a spectral primitive equation atmospheric GCM. The method, which is based on the Ensemble Kalma...
Estimating surface CO2 fluxes from space-borne CO2 dry air mole fraction observations using an ensemble Kalman Filter
surface CO2 fluxes space-borne CO2 ensemble Kalman Filter
2009/5/6
We have developed an ensemble Kalman Filter (EnKF) to estimate 8-day regional surface fluxes of CO2 from space-borne CO2 dry-air mole fraction observations (XCO2) and evaluate the approach using a ser...
A method for evaluating spatially-resolved NOx emissions using Kalman filter inversion, direct sensitivities, and space-based NO2 observations
NOx Kalman filter space-based NO2
2008/11/20
An inverse modeling method was developed and tested for identifying possible biases in emission inventories using satellite observations. The relationships between emission inputs and modeled ambient...
An Ensemble Kalman Filter for severe dust storm data assimilation over China
Ensemble Kalman Filter dust storm China
2008/11/10
An Ensemble Kalman Filter (EnKF) data assimilation system was developed for a regional dust transport model. This paper applied the EnKF method to investigate modeling of severe dust storm episodes oc...
