Data Assimilation, Reanalysis, and Observing System Simulation Experiments: Theory and Applications

Session ID#: 75210

Session Description:
Data assimilation is a sequential process that incorporates satellite and in-situ observations into a background state (forecast) provided by the NWP models. The model state is then updated and a new forecast is initiated which will be used to provide the background state for the next assimilation cycle. This session is devoted to assimilation of spaceborne and conventional observations into NWP models; development, validation, and inter-comparison of reanalysis products; new advanced statistical and mathematical methods for data assimilation; as well as Observing System Simulation Experiments (OSSE) including simulation of realistic observations, validation of Nature Runs, and data assimilation experiments using simulated observations.
