Observing System Evaluation - TT (OSEval-TT)

OSEImpact of Argo, SST and altimeter data on an eddy-resolving reanalysis (Oke, P. R., and A. Schiller, 2007, Geophys. Res. Lett., 34, L19601, doi:10.1029/2007GL031549)


Task Team Mission

One of the aims of the GODAE OceanView Observing System Evaluation Task Team (OSEval-TT) is to formulate more specific requirements for ocean observations on the basis of improved understanding of data utility.

The OSEval-TT is jointly formed by GODAE OceanView and the Ocean Observation Panel for Climate (OOPC). Through the task team, GODAE OceanView and OOPC partners will get organized at the international level to provide evidence-based responses to agencies and organizations in charge of sustaining the global and regional ocean observing systems used for ocean monitoring and forecasting at short-range, seasonal and decadal time-scales.

This activity requires consistent protocols for observation impact assessment, tools for routine production of appropriate diagnostics, common sets of metrics for inter-comparison of results, and objective methodologies for observing system design and assessment activities.
