NPBY1 - Point Wells: L3 Depth Gridded Data - 0.25 meter

The Northwest Environmental Moorings program maintains
a number of buoys thoughout the Puget Sound region, taking regular profiling
casts with a winched CTD attached to a fixed mooring. These profiles measure
water pressure, water temperature, and conductivity. Depending on the mooring
configuration, additional instruments are added to take further measurements,
which can include dissolved oxygen, nitrate concentrations, fluoroescence
(a proxy measurement for chlorophyll concentrations), and turbidity.

This data has converted raw profiles into a gridded data product. Data from the downcast (i.e., from surface to maximum depth) is extracted, and used to grid each variable to pre-defined pressure levels. Quality control flags are used to improve gridded data quality. Bad data is removed during gridding, while suspect data is flagged. Using the pressure-gridded data, corresponding hydrostatic depths are calculated. From these hydrostatic depths, the data is then interpolated onto fixed depth levels.

This dataset has historical data, and adds new data shortly after any additional casts
have been performed. Data quality delay is usually less than 6 hrs.

西北环境锚泊项目于普吉特湾地区维护了一系列浮标，通过固定锚泊，定期使用绞车连接的CTD进行剖面测量。这些剖面测量数据包括水压、水温、电导率。根据锚泊配置的不同，还会增加额外的仪器进行进一步测量，可能包括溶解氧、硝酸盐浓度、荧光（作为叶绿素浓度代理的测量）和浑浊度。该数据集将原始剖面数据转换为网格化数据产品。下潜数据（即从水面至最大深度）被提取出来，并用于将每个变量网格化至预定义的压力水平。质量控制标志被用于提升网格化数据的质量。在网格化过程中，不良数据被移除，而可疑数据则被标记。利用压力网格化数据，计算相应的静力深度。从这些静力深度出发，数据随后被插值至固定深度水平。该数据集包含历史数据，并在进行任何附加测量后不久添加新数据。数据质量延迟通常不超过6小时。数据版本为2，使用的网络共同数据格式（NetCDF）版本为4.9.0，使用的HDF5版本为1.12.2。作者为Seth Travis，浮标标识为NPBY1，浮标纬度为北纬47.76116666度，浮标经度为东经-122.39716666度，浮标名称为Pt.
