Western Indian Ocean Energy Sinks (WOES) 0.25: a CROCO numerical ocean model hindcast at 1/4 degree monthly climatologies for the south western Indian Ocean from 1993-2014.

This realistic ocean simulation was run using the Coastal and Regional Ocean COmmunity model (CROCO), based on the Regional Ocean Modelling System (ROMS), which has 60 terrain-following vertical levels. This output (WOES 0.25) is the largest grid of a triply nested configuration: WOES I, WOES II and WOES III, with horizontal resolutions of ~22.5, 7.5 and 2.5 km respectively. Monthly ouputs of the 0.25 degree GLORYS ocean reanalysis is used to force the boundaries of WOES I. The surface forcing for this model is provided by a bulk formulation using daily ERA-Interim atmospheric reanalysis (with a resolution of ~80 km) and using a relative wind approach. The output is saved as daily averages, in monthly netcdf files spanning January 1993 - December 2014. WOES 0.25 spans 55.7degS to 3.18388 degS and 10degW to 102.25degE and covers most of the Southern Subtropical Indian Ocean and a part of the Southern Atlantic Ocean. Model output includes: averaged free-surface (zeta), averaged vertically integrated u-momentum component (ubar), averaged vertically integrated v-momentum component (vbar), averaged u-momentum component (u), averaged v-momentum component (v), averaged potential temperature (temp), averaged salinity (salt), averaged vertical momentum component (w).

本真实海洋模拟采用基于区域海洋模拟系统（Regional Ocean Modelling System，ROMS）的海岸与区域海洋共同体模型（Coastal and Regional Ocean COmmunity model，CROCO）运行，该模型包含60个地形跟随垂直层。本输出（WOES 0.25）是三重嵌套配置（WOES I、WOES II和WOES III）中网格规模最大的一组，三者的水平分辨率分别约为22.5公里、7.5公里和2.5公里。0.25度GLORYS海洋再分析的月度输出被用于驱动WOES I的边界。该模型的表面驱动由体积公式提供，采用每日ERA-Interim大气再分析数据（分辨率约80公里）及相对风方法。输出结果以日平均值形式保存于月度NetCDF文件中，时间跨度为1993年1月至2014年12月。WOES 0.25覆盖范围为南纬55.7度至南纬3.18388度、西经10度至东经102.25度，包含南亚热带印度洋大部分区域及南大西洋部分区域。模型输出包含：平均自由表面（zeta）、平均垂向积分u动量分量（ubar）、平均垂向积分v动量分量（vbar）、平均u动量分量（u）、平均v动量分量（v）、平均位温（temp）、平均盐度（salt）、平均垂向动量分量（w）。数值计算在IDRIS（法国国家科学计算与开发研究所，Institut du Developpement et des Ressources en Informatique Scientifique）的IBM "ADA"计算机设施上完成（资助编号A0020107630）。
