Four-dimensional Variational Ocean ReAnalysis for the Western North Pacific (FORA-WNP30) is the first-ever dataset covering the western North Pacific over the last three decades (1982-2014) at eddy-resolving resolution. This is the cooperative work of Japan Agency for Marine-Earth Science and Technology (JAMSTEC) and Meteorological Research Institude, Japan Meteorological Agency (JMA/MRI) using the Earth Simulator.
Details of the dataset are described in Dataset page.
FORA-WNP30 was produced by using MRI Multivariate Ocean Variational Estimation system, version of 4-dimensional variational method (MOVE-4DVAR; Usui et al. 2015), the data assimilation system developed by the JMA/MRI. MOVE-4DVAR uses MRI.COM-WNP (Tsujino et al. 2006), eddy-resolving ocean model for Western North Pacific developed by JMA/MRI, as the forward model of ocean and sea ice.
The settings of the assimilation system are as follows:
|Variable name||Dimension||Standard name*1||Units*2|
Japan Agency for Marine-Earth Science and Technology (JAMSTEC) and Meteorological Research Institude, Japan Meteorological Agency (JMA/MRI) provide Four-dimensional variational Ocean ReAnalysis for the Western North Pacific (FORA-WNP30) as a basic ocean reanalysis dataset for research activities in ocean, climate and other related fields. The computational resources for the dataset is provided by the Earth Simulator in the Strategic Project with Special Support of JAMSTEC. The dataset is available under the terms and conditions and the constraints listed below.
The dataset is available for free for scientific and educational purposes. If you use the dataset, please contact JAMSTEC/CEIST by the email with
