Data of long-term model simulation on the Gulf of Finland, the Baltic Sea

The dataset have been used to prepare the article "Long-term mean and monthly circulation in the Gulf of Finland, the Baltic Sea". Citing that article would be appropriate way to credit this dataset. The dataset is derived from simulation results from the 40-year model run for the Gulf of Finland. Model applied: 3D hydrodynamical model General Estuarine Transport Model (GETM). Horizontal resolution 1 nautical mile. Vertical resolution 40 adaptive layers. Simulation period 1966-2006. Model description and validation is described in Maljutenko and Raudsepp (2014). Climate Data Operators (CDO) toolbox have been used for statistical post-processing (history stored in files). Dataset contains 3 different NetCDF sub-datasets: 1. Average over simulation period 3D fields, 2. Monthly mean 3D fields, 3. Daily mean profiles from selected stations (folder "Stations"). 3D variables are salinity (saltmean), temperature (tempmean), meridional velocity (vvmean), zonal velocity (uumean), vertical velocity (wmean), mean velocity (velmean) , layer thickness (hmean). 2D variables umean and vmean correspond to the barotropic velocity components. The vertical coordinates are given in variable layer heights, such that z-levels must be calculated from water depths (bathymetry) and vertical layer thicknesses (hmean). The location of selected stations can be obtained from the included coordinates in variables of lonc and latc.

本数据集用于支撑论文《波罗的海芬兰湾长期平均环流与逐月环流》的撰写，引用该论文是对本数据集进行致谢的恰当方式。本数据集源自针对芬兰湾开展的40年数值模拟结果。所用数值模型为三维水动力模型通用河口输运模型（General Estuarine Transport Model, GETM），水平分辨率为1海里，垂直方向设置40个自适应分层，模拟时段为1966年至2006年。该模型的描述与验证细节详见Maljutenko与Raudsepp（2014）的研究成果。统计后处理环节采用了气候数据运算工具包（Climate Data Operators, CDO），相关处理历史存储于对应文件中。本数据集包含3个不同的NetCDF子数据集：1. 模拟时段平均三维场；2. 逐月平均三维场；3. 选定观测站点的逐日平均剖面（存储于名为"Stations"的文件夹中）。三维变量包括盐度（saltmean）、温度（tempmean）、经向流速（vvmean）、纬向流速（uumean）、垂向流速（wmean）、平均流速（velmean）以及垂直分层厚度（hmean）。二维变量umean与vmean对应正压流速分量。垂直坐标由分层高度变量提供，需结合实测水深（bathymetry）与垂直分层厚度（hmean）计算z层坐标。选定观测站点的空间位置可通过文件中包含的lonc与latc坐标变量获取。
