Modeling and data assimilation/visualization Services
ERT provides research through operations support via high-end atmospheric modeling and data assimilation of air quality and emissions forecasting trajectories and deposition for NOAA Air Resources Lab and implementation into the NOAA NCEP operations. ERT integrates atmospheric emissions into analytical models, couple the models to describe physical and chemical evolution of atmospheric plumes, assemble observational data, and test each model against the observational data.ERT performs high performance computing integration, testing, evaluation, and system administration activities for the JCSDA/NOAA/NESDIS in its mission to compare, test, and evaluate a variety of NWP models and satellite data assimilation approaches from the various partners including NASA, DoD, NCAR, and NOAA NCEP. ERT develops and tests data assimilation quality control and data preparation approaches for current operational satellites, as well as upcoming next generation satellite systems.
ERT supports NOAA National Geodetic Survey (NGS) in the geoid modeling of the Earth`s surface. These models are used extensively in charting and are also relevant to efforts to determine sea level changes and long-term climatic changes. ERT staff develop and enhance the accuracy of the geoid models and develops visualization tools of model outputs.
ERT oceanographic modeling activities include NOAA/NOS plume modeling calibration and practical modeling set-up, ArcGIS experimental development for generating new graphical products for the display of oceanographic forecast model output, and development of a high-resolution marine grid to be used for populating the VDatum results.
