The first author gratefully acknowledges the work of Roger Daley and Ed
Barker in developing the NAVDAS solution algorithm which forms the basis of the NCODA
3DVAR. This work was funded in part by NRL base projects “Variational Data Assimilation for
Ocean Prediction” and “Observation Impact using a Variational Adjoint System”. Funding was also
received from the National Ocean Partnership Program (NOPP) through the project “US GODAE:
Global-Ocean Prediction with the HYbrid Coordinate Ocean Model (HYCOM)” and the Office
of Naval Research (ONR) under program element number 61153 N. The Department of Defense
High Performance Computing Modernization Program provided grants of computer time at Major
Shared Resource Centers operated by the Naval Oceanographic Office, Stennis Space Center, MS,
USA. This is NRL contribution NRL/BC/7320-12-1125 and has been approved for public release.
Distribution is unlimited.
