Assimilation of HF Radar Observations in the Chesapeake-Delaware Bay Region Using the Navy Coastal Ocean Model (NCOM) and the Four-Dimensional Variational (4DVAR) Method

Abstract

Consistent and accurate coastal ocean monitoring necessitates the availability of three key components: ( I) an observing network that adequately samples the monitored domain, (2) a coastal ocean circulation model with a sufficiently high resolution that takes into account the often complex geometry and dynamics that occur near the coastline, and (3) an analysis system that is able to accurately assimilate the sampled observations to initialize the coastal model for forecasting. Modern analysis systems can also provide an observation impact assessment for the design, evaluation, and possibly reassignment of observing resources.
