This proposal outlines a partnership between NOAA and NASA to promote the use of NASA Earth science research results within NOAA decision support systems in order to improve the Nation¿s environmental forecasts that protect public health, life and property. This NOAA-NASA collaborative project will enable the capabilities of global aerosol forecasting and assimilation in NOAA operational global forecasting and assimilation system (GFS/GDAS), resulting from the adoption of a NASA aerosol modeling component (GOCART) and the utilization of NASA satellite-based aerosol measurements (CALIPSO, OMI, and MODIS). This project will be executed in close collaboration with the NASA-NOAA-DOD Joint Center for Satellite Data Assimilation, whose resources will be leveraged to improve the Sea Surface Temperature analyses. Time continuous, global aerosol concentrations from the GFS-GOCART system will provide more accurate particulate matter lateral boundary conditions for NOAA¿s National air quality forecast mission, improve the accuracy of medium-range weather prediction, and enable more accurate global SST analysis. Primary outputs of this project include (1) a prototype system that incorporates the NASA aerosol model and satellite measurements within the NOAA weather and air quality decision support tools and (2) benchmark reports that document the anticipated improvements in NOAA weather and air quality forecasts relative to the current baseline. An end-to-end work plan will be employed to ensure a timely and robust transition from NASA Earth science research results into NOAA operational applications.
