Towards operational data assimilation of satellite-based aerosol observations in a chemical transport model for air quality monitoring

TL;DRAbstract

Aerosol monitoring is of growing interest due to the impact of aerosol particle concentration on human health and the global climate. Additionally, increased attention is spent from the economic viewpoint towards aerosol-induced variations in surface solar irradiance which is the resource for solar electricity generation and a driver for electricity consumption in general. Air quality models as the EURopean Air pollution Dispersion model EURAD offer a continuous and operational monitoring and forecasting of the aerosol load in sufficient temporal and spatial resolution. But they fail in case of episodic emissions which are not covered by the underlying emission data bases used to describe aerosol sources. Also, emission data bases are in general still not sufficient in terms of accuracy, long term trends and temporal-spatial resolution.
