NAVDAS is tested and compared to the existing operational system, a multivariate optimal interpolation scheme using the Navy Operational Global Atmospheric Prediction System. Initial comparisons are made with both systems configured as close to one another as possible. Additional comparisons are used to compare individual cases as well as a statistical validation over different seasons. Incremental addition of NAVDAS features are then tested and compared to the baseline run established using the earlier comparison runs.
In this presentation, NAVDAS performance will be described to include computer efficiency, forecast improvement, and details in the resulting analyses.
