Our long-term goal is to develop a 4-dimensional variational 4D-Var data assimilation system using the COAMPS Coupled OceanAtmosphere 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., SSMI Special Sensor MicrowaveImager 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.
