Application of Earth Sciences Products for use in Next Generation Numerical Aerosol Prediction Models

摘要

The long-term goal of this project is to devise a forward modeling system to characterize and predict clear sky radiation fields through the harvest of a number of preexisting basic research programs funded by Navy and other government agencies (NASA, NOAA, DOE, etc.). With an aerosol radiance forward model, we will be able to combine model aerosol background fields from the NRL Aerosol Analysis and Prediction System (NAAPS) and Coupled Ocean Atmosphere Mesoscale Prediction System (COAMPS(registered name) 1) with near real time satellite surface and aerosol products to generate a real-time aerosol analysis field for aerosol model initialization. Through this aerosol data assimilation system, we will be able to advance a number of US Navy Applied Science needs in the areas of improved Electro Optical (EO) propagation prediction and aerosol meteorology interaction. Further development of the Navy's atmospheric constituent data assimilation system depends on our focused efforts, including the utilization of a number of satellite-based products. The evaluation and characterization of relevant satellite products, including passive aerosol retrievals, lidar profiles, and other relevant cloud and precipitation products, does require substantial effort, but will feed into a system for the calculation and improvement of atmospheric radiance fields from Navy meteorological data feeds. Our work will also enable quasi-operational computations of aerosol impacts on atmospheric diabatic heating rates and surface fluxes, as well as provide a significant upgrade to the Navy's aerosol data assimilation system through the inclusion of a number of additional satellite sensors. Lastly our efforts will significantly improve source and sink functions for Navy, as well as outside aerosol models, and prepare for expected data gaps in the early 2010's.
