Satellite nadir observations in the UV, visible, and short-wave infrared wavelength range are currently being used in aerosol monitoring for air quality and climate applications employing data assimilation techniques. The classic approach of assimilating Level-2 Aerosol Optical Depth (AOD) is error prone due to unavoidable inconsistencies in assumed aerosol microphysical parameters. The proposed activity is dedicated to an implementation and testing of an alternative approach based on the assimilation of radiances. This scheme is applied on a dataset from one well-calibrated satellite instrument with good aerosol capabilities. The study concludes withthe assessment of the aerosol monitoring skill of the radiance-based assimilation scheme and comparison with the AOD-based assimilation scheme, using independent aerosol reference data.
