abstract = "The first version of the Brazilian Oceanographic Modeling and
Observation Network (REMO) ocean data assimilation system into the
Hybrid Coordinate Ocean Model (HYCOM) (RODAS_H) has recently been
constructed for research and operational purposes. The system is
based on a multivariate Ensemble Optimal Interpolation (EnOI)
scheme and considers the high frequency variability of the model
error co-variance matrix. The EnOI can assimilate sea surface
temperature (SST), satellite along-track and gridded sea level
anomalies (SLA), and vertical profiles of temperature (T) and
salinity (S) from Argo. The first observing system experiment was
carried out over the Atlantic Ocean (78°S50°N, 100°W20°E) with
HYCOM forced with atmospheric reanalysis from 1 January to 30 June
2010. Five integrations were performed, including the control run
without assimilation. In the other four, different observations
were assimilated: SST only (A_SST); Argo T-S profiles only
(A_Argo); along-track SLA only (A_SLA); and all data employed in
the previous runs (A_All). The A_SST, A_Argo, and A_SLA runs were
very effective in improving the representation of the assimilated
variables, but they had relatively little impact on the variables
that were not assimilated. In particular, only the assimilation of
S was able to reduce the deviation of S with respect to
observations. Overall, the A_All run produced a good analysis by
reducing the deviation of SST, T, and S with respect to the
control run by 39%, 18%, and 30%, respectively, and by increasing
the correlation of SLA by 81%.",
