dc.description.abstract | Ocean reanalyses combine ocean models, atmospheric forcing fluxes, and observations
using data assimilation to give a four-dimensional description of the ocean. Metrics
assessing their reliability have improved over time, allowing reanalyses to become an
important tool in climate services that provide a more complete picture of the changing
ocean to end users. Besides climate monitoring and research, ocean reanalyses are
used to initialize sub-seasonal to multi-annual predictions, to support observational
network monitoring, and to evaluate climate model simulations. These applications
demand robust uncertainty estimates and fit-for-purpose assessments, achievable
through sustained advances in data assimilation and coordinated inter-comparison
activities. Ocean reanalyses face specific challenges: (i) dealing with intermittent or
discontinued observing networks, (ii) reproducing inter-annual variability and trends of
integrated diagnostics for climate monitoring, (iii) accounting for drift and bias due, e.g.,
to air-sea flux or ocean mixing errors, and (iv) optimizing initialization and improving
performances during periods and in regions with sparse data. Other challenges such as
multi-scale data assimilation to reconcile mesoscale and large-scale variability and flowdependent
error characterization for rapidly evolving processes, are amplified in longterm
reanalyses. The demand to extend reanalyses backward in time requires tackling
all these challenges, especially in the emerging context of earth system reanalyses and
coupled data assimilation. This mini-review aims at documenting recent advances from
the ocean reanalysis community, discussing unsolved challenges that require sustained
activities for maximizing the utility of ocean observations, supporting data rescue and
advancing specific research and development requirements for reanalyses. | en_US |
