Combined DIVA 4D 10-year analysis of Water body dissolved oxygen concentration

Combined product of Water body dissolved oxygen concentration based on DIVA 4D 10-year analysis on five regions : Atlantic Sea, North Sea, Baltic Sea, Black Sea, Mediterranean Sea. The boundaries and overlapping zones between these five regions were filtered to avoid any unrealistic spatial discontinuities. This combined water body dissolved oxygen concentration product is masked using the relative error threshold 0.5. Units: umol/l."" Created by 'University of Liege, GeoHydrodynamics and Environment Research (ULg-GHER)'."" The analysis was performed per season using DIVA software tool (Data-Interpolating Variational Analysis). The analyses products are stored as NetCDF CF files and made available as WMS layers for easy browsing and adding. Every step of the time dimension corresponds to a 10-year average moving from 1985 to 2014. The depth dimension spans from surface to the seafloor with 30 vertical levels.""

本数据集为针对大西洋、北海、波罗的海、黑海、地中海五大海域，基于DIVA 4D（Data-Interpolating Variational Analysis，数据插值变分分析）开展的10年分析结果融合得到的水体溶解氧浓度组合产品。对该五大海域的边界及重叠区域进行了滤波处理，以规避不合理的空间不连续现象。本组合水体溶解氧浓度产品采用相对误差阈值0.5进行数据掩膜处理。单位：umol/l。本数据集由列日大学地球流体动力学与环境研究中心（University of Liege, GeoHydrodynamics and Environment Research, ULg-GHER）制作。分析工作按季节开展，使用DIVA软件工具（Data-Interpolating Variational Analysis，数据插值变分分析）完成。分析产物以NetCDF CF格式存储，并以WMS（Web Map Service，网络地图服务）图层形式对外提供，便于浏览与添加使用。时间维度的每一时间步均对应1985年至2014年间的10年滑动平均值。深度维度覆盖从海水表层至海底的全水深范围，共设置30个垂直分层。用于DIVA分析的输入数据提取自EMODnet Chemistry下载服务：http://emodnet-chemistry.maris2.nl/v_cdi_v3/search.asp。区域中间数据集产品如下：
