Development of the COAMPS (trademark) Adjoint Modeling System and Its Application to Storm Initialization Using SSM/I Observations

Abstract

Our long-term goal is to develop a 4-dimensional variational (4D-Var) data assimilation system using the COAMPS (Coupled Ocean/Atmosphere Mesoscale Prediction System) atmospheric model, which could be used for many applications in mesoscale numerical weather prediction. Once completed, the system can be used to assess the impact of remote-sensing observations (e.g., SSM/I (Special Sensor Microwave/Imager) microwave radiances and QSCAT (QuikSCAT) surface winds) on mesoscale and storm-scale prediction. Adjoint sensitivity studies can also be conducted with this system in analyzing model forecasts. The system can potentially be used operationally at the Naval Research Laboratory (NRL) if there is an appropriate level of computing power available.
