Mediterranean Sea, Po River, DIVAnd 4D seasonal analysis of Water body dissolved oxygen concentration 1960/2020 v2023 [time][lat][lon], 0.009°, 1990

Mediterranean Sea - Po River - DIVAnd 4D seasonal analysis of Water body dissolved oxygen concentration 1960/2020 v2023. Water body chlorophyll-a - Seasonal Climatology for Po River for the period 1960-2020 on the domain: Lon E12.0-14.0deg., Lat N44.0-46.0deg.
Data Sources: observational data from SeaDataNet/EMODNet Chemistry Data Network.
Description of DIVA analysis: The computation was done with the DIVAnd (Data-Interpolating Variational Analysis in n dimensions), version 2.7.9, using GEBCO 30sec topography for the spatial connectivity of water masses.
The horizontal resolution of the produced DIVAnd maps grids is dx=dy=0.009 degrees (around 975m and 708m accordingly).
The vertical resolution is 14 depth levels: [0., 2., 4., 6., 8., 10., 15., 20., 25., 30., 40., 50., 60., 70.].
A relative correlation length used based on topography gradients and the horizontal correlation length varies from 25 km to 12.5 km. The vertical correlation length (in meters) is: [4.,4.,4.,4.,4.,10.,10.,10.,10.,20.,20.,20.,20.,20.].
Duplicates check was performed using the following criteria for space and time: dlon=0.01deg., dlat=0.01deg., ddepth=0.01m, dtime=1min, dvalue=0.01.
The error variance (epsilon2) was set equal to 1. Data weight was reduced at shallow waters. Data weighting was applied with the following threshold values: lon=0.03, lat=0.03, depth=2.
An anamorphosis transformation was applied to the data (function DIVAnd.Anam.loglin) to avoid unrealistic negative values: threshold value=200.
The mean value was used as background analysis field.
Quality control of the observations was applied using the interpolated field (QCMETHOD=3). Residuals (differences between the observations and the analysis (interpolated linearly to the location of the observations) were calculated. Observations with residuals outside the minimum and maximum values of the 99% quantile were discarded from the analysis.
Seasons definition: Winter=Jan-Mar, Spring=Apr-Jun, Summer=Jul-Sep, Autumn=Oct-Dec.

地中海海域 - 波河 - 使用DIVAnd方法对1960年至2020年期间水体溶解氧浓度的四维季节性分析。水体叶绿素a - 波河1960-2020年期间季节性气候学，研究区域：经度E12.0-14.0度，纬度N44.0-46.0度。
数据来源：来自SeaDataNet/EMODNet化学数据网络的观测数据。
DIVA分析描述：计算采用DIVAnd（n维数据插值变分分析），版本2.7.9，利用GEBCO 30秒地形数据来构建水团的空间连通性。
生成的DIVAnd地图网格的水平分辨率为dx=dy=0.009度（大约为975米和708米）。
垂直分辨率为14个深度层级：[0., 2., 4., 6., 8., 10., 15., 20., 25., 30., 40., 50., 60., 70.]。
基于地形梯度，相对相关长度和水平相关长度变化范围为25公里至12.5公里。垂直相关长度（以米为单位）为：[4.,4.,4.,4.,4.,10.,10.,10.,10.,20.,20.,20.,20.,20.]。
使用以下空间和时间标准进行重复检查：dlon=0.01度，dlat=0.01度，ddepth=0.01米，dtime=1分钟，dvalue=0.01。
误差方差（epsilon2）设置为1。在浅水区域降低数据权重。应用以下阈值的数据加权：lon=0.03，lat=0.03，深度=2。
对数据进行非畸变变换（函数DIVAnd.Anam.loglin）以避免不现实的负值：阈值值=200。
以平均值作为背景分析场。
使用插值场（QCMETHOD=3）对观测进行质量控制。计算观测值与分析（线性插值至观测位置）之间的残差。丢弃残差超出99%分位数最小和最大值的观测值。
季节定义：冬季=1月-3月，春季=4月-6月，夏季=7月-9月，秋季=10月-12月。
