| Summary: | <p>A 10-year reanalysis of the PacIOOS Hawaiian Island Ocean Forecast System was
produced using an incremental strong-constraint 4-D variational data
assimilation with the Regional Ocean Modeling System (ROMS v3.6).
Observations were assimilated from a range of sources: satellite-derived sea
surface temperature (SST), salinity (SSS), and height anomalies (SSHAs); depth
profiles of temperature and salinity from Argo floats, autonomous Seagliders,
and
shipboard conductivity–temperature–depth (CTD); and surface velocity
measurements from high-frequency radar (HFR). The performance of the
state estimate is examined against a forecast showing an improved
representation of the observations, especially the realization of HFR surface
currents. EOFs of the increments made during the assimilation to the initial
conditions and atmospheric forcing components are computed, revealing the
variables that are influential in producing the state-estimate solution and
the spatial structure the increments form.</p> |
