One of the strategies to improve the Navy Aerosol Analysis and Prediction System NAAPS electrooptical propagation forecast capability is through operational aerosol data assimilation. This process of combining the strength of both near real time aerosol observations and aerosol model predictions has only becomes feasible in the past few years. The assimilation of satellite observations into numerical models is now commonplace. However, only a few attempts have been made to assimilate satellite aerosol products into numerical models. Methods include using an Optimal Interpolation OI technique, mainly through retrospective studies or limited regional studies and most recently through radiance assimilation. Based on a previous NRL award, a first of its kind aerosol optical depth data assimilation system was developed. Our long term goals are to improve the long term stability of the system, and to allow for the easy application of data from multiple satellite sensors.
