Generating an accurate vertical aerosol profile

The development of an active optical system operating from a shipboard platform will require marine-specific models to predict the atmospheric channel characteristics. Given the variable nature of maritime operational areas, a second important component of a successful system is the integration of local and timely environmental measurements. We describe work to develop a model for beam propagation on an uplink in a maritime environment. Both extinction and turbulence can be important factors in beam degradation, and the prediction capability will require reliable models based upon local data, including meteorological data. Our focus is the determination of model fidelity for engagement scenarios of practical interest. We also discuss the need for quality-assured data and the possibilities for more direct channel assessments.
