In this study, we demonstrate the improvements in aerosol analysis and forecasts through assimilation of satellite aerosol observations, exploring both direct and indirect impacts of aerosol particles on weather forecasts, and highlight the potential of using Ozone Monitoring Instrument (OMI) data for improving aerosol analysis over the Arctic region.

The first part of the study shows the improvements of Navy Aerosol Analysis and Prediction System(NAAPS) aerosol analysis and forecasts with the assimilation of Terra and Aqua satellite aerosol data. We further explore the impact of a non-analyzed smoke plume on forecast near surface atmospheric properties, as well as evaluate the influence of assimilating dust-laden infrared hyperspectral radiances on model analysis of temperature and dew point.

In the second part of the study, we highlight the lack of assimilation-quality satellite data over the ice-covered Arctic region in the Earth Observing System(EOS) data records. Finally, we explore the potential for improving aerosol analysis over the previously data-sparse Arctic region using OMI data.
