dc.description.abstract | This paper summarizes recent efforts on Observing System Evaluation (OS-Eval) by
the Ocean Data Assimilation and Prediction (ODAP) communities such as GODAE
OceanView and CLIVAR-GSOP. It provides some examples of existing OS-Eval
methodologies, and attempts to discuss the potential and limitation of the existing
approaches. Observing System Experiment (OSE) studies illustrate the impacts of the
severe decrease in the number of TAO buoys during 2012–2014 and TRITON buoys
since 2013 on ODAP system performance. Multi-system evaluation of the impacts of
assimilating satellite sea surface salinity data based on OSEs has been performed to
demonstrate the need to continue and enhance satellite salinity missions. Impacts of
underwater gliders have been assessed using Observing SystemSimulation Experiments
(OSSEs) to provide guidance on the effective coordination of the western North Atlantic
observing system elements. OSSEs are also being performed under H2020 AtlantOS project with the goal to enhance and optimize the Atlantic in-situ networks. Potential of
future satellite missions of wide-swath altimetry and surface ocean currents monitoring is
explored through OSSEs and evaluation of Degrees of Freedomfor Signal (DFS). Forecast
Sensitivity Observation Impacts (FSOI) are routinely evaluated for monitoring the ocean
observation impacts in the US Navy’s ODAP system. Perspectives on the extension of
OS-Eval to coastal regions, the deep ocean, polar regions, coupled data assimilation,
and biogeochemical applications are also presented. Based on the examples above,
we identify the limitations of OS-Eval, indicating that the most significant limitation is
reduction of robustness and reliability of the results due to their system-dependency.
The difficulty of performing evaluation in near real time is also critical. A strategy to
mitigate the limitation and to strengthen the impact of evaluations is discussed. In
particular, we emphasize the importance of collaboration within the ODAP community for
multi-system evaluation and of communication with ocean observational communities
on the design of OS-Eval, required resources, and effective distribution of the results.
Finally, we recommend further developing OS-Eval activities at international level with
the support of the international ODAP (e.g., OceanPredict and CLIVAR-GSOP) and
observational communities. | en_US |
