Aerosol Microphysics and Radiation Integration
Abstract
This long-term goals of this project is the development of systems that support real time global prognostic aerosol and visibility models for the benefit of the Department of Defense and civilian research communities. Aerosol particle light extinction and absorption properties vary considerably by region, and aerosol models struggle with complex and harsh environments. Visibility degradation is a chronic issue in many sensitive parts of the globe, including the Arabian Gulf/Arabian Sea, East Asia, and some parts of the Mediterranean Sea. Along coastal and even some deep ocean regions, dust, pollution and smoke are often present and can dominate Electro-Optical (EO) effects over simple sea salt. In order to account for these varied aerosol species, models such as the Coupled Ocean/Atmosphere Mesoscale Prediction System (COAMPS 1) and the NRL Aerosol Analysis and Prediction System (NAAPS) require precise source and sink functions, as well as parameterizations for particle size, chemistry, and optical properties. Similar microphysical data are required for remote sensing systems. A consistent aerosol microphysics and radiation model is necessary if aerosol forecasting systems are to make the leap to satellite data utilization. As the models are so heavily dependent on derived microphysical parameterizations and remote sensing data, this program is deeply involved in the model data assimilation and validation effort. Ultimately, the aerosol parameterizations generated by this research will be transitioned into Navy transport, EO propagation, and visibility models. We provide support to the operational systems when implemented, and assesses model efficacy.
