Data Assimilation Unit

Collaboration with the National Center for Atmospheric Research (NCAR) helped develop the Data Assimilation Research Testbed (DART) interface to the GCCOM. The DART-GCCOM assimilation system is enabled for multivariate assimilation of several ocean data sets. This includes satellite surface temperature and altimetry data, in-situ temperature, and salinity and velocity data, including high-frequency radar surface current measurements. Data assimilation has the ability to improve the speed and quality of coastal ocean model development and is becoming an integral part of that process. With the GCCOM, this research group demonstrates how data assimilation can be used with a non-hydrostatic coastal ocean model to study sub-mesoscale processes and accurately estimate the state variables.
