Argo float vertical profile R4903255_014

These data are ocean profile data measured by profiling Argo S2A floats at a specific latitude, longitude, and date nominally from the surface to 2000 meters depth. Pressure, in situ temperature (ITS-90), and practical salinity are provided at 1-m increments through the water column. Argo data from Gulf of Mexico (GOM) LC1 (9 floats) and LC2 (12 floats) were delayed mode quality controlled and submitted to Global Data Assembly Centers (GDACs) in May 2020. All available profiles are planned to be revisited and evaluated in early 2021. Float no. 4903233 started showing drift in salinity at profile no. 77, and the salinity data will be carefully examined with a new adjustment in early 2021.

note_CHAR_variables=RPS METADATA ENHANCEMENT NOTE
Variables of data type 'CHAR' have been altered by the xarray and netCDF4-python libraries to contain an extra dimension (often denoted as 'string1'). This is due to an underlying issue in the libraries: https://github.com/pydata/xarray/issues/1977. Upon examination, one will find the data has not been altered but only changed shape. We realize this is sub-optimal and apologize for any inconveniences this may cause.
note_FillValue=RPS METADATA ENHANCEMENT NOTE
Many variables in this dataset are of type 'char' and have a '_FillValue' attribute which is interpreted through NumPy as 'b', an empty byte string. This causes serialization issues. As a result, all variables of type 'char' with '_FillValue = b' have had the _FillValue attribute removed to avoid serialization conflicts. However, no data has been changed, so the _FillValue is still "b' '".

processing_level=Argo data are received via satellite transmission, decoded and assembled at national DACs. These DACs apply a set of automatic quality tests (RTQC) to the data, and quality flags are assigned accordingly. In the delayed-mode process (DMQC), data are subjected to visual examination and are re-flagged where necessary. For the float data affected by sensor drift, statistical tools and climatological comparisons are used to adjust the data for sensor drift when needed. For each float that has been processed in delayed-mode, the OWC method (Owens and Wong, 2009; Cabanes et al., 2016) is run with four different sets of spatial and temporal decorrelation scales and the latest available reference dataset. If the salinity adjustments obtained from the four runs all differ significantly from the existing adjustment, then the salinity data from the float are re-examined and a new adjustment is suggested if necessary. The usual practice is to examine the profiles in delayed-mode initially about 12 months after they are collected, and then revisit several times as more data from the floats are obtained (see details in Wong et al., 2020).

本数据集包含由 Argo S2A 漂浮体在特定纬度、经度和日期下从海面至2000米深度范围内测量的海洋剖面数据。数据以1米间隔提供了压力、现场温度（ITS-90）和实际盐度。墨西哥湾（GOM）LC1（9个浮标）和LC2（12个浮标）的 Argo 数据在2020年5月进行了延迟模式质量控制和提交至全球数据汇编中心（GDACs）。所有可用的剖面计划在2021年初进行回顾和评估。浮标编号4903233在第77次剖面开始显示出盐度漂移，盐度数据将在2021年初进行仔细检查并作出新的调整。

- 字符变量备注：RPS 元数据增强备注
- 变量类型 'CHAR' 已由 xarray 和 netCDF4-python 库修改，包含一个额外的维度（通常表示为 'string1'）。这是由于库中存在一个潜在问题：https://github.com/pydata/xarray/issues/1977。经过检查，发现数据并未被修改，只是改变了形状。我们意识到这是不理想的，并对可能造成的任何不便表示歉意。
- 填充值备注：RPS 元数据增强备注
- 许多变量类型为 'char' 并具有 '_FillValue' 属性，通过 NumPy 解释为 'b'，一个空字节字符串。这导致序列化问题。因此，所有类型为 'char' 且 '_FillValue = b' 的变量已移除 _FillValue 属性，以避免序列化冲突。然而，没有数据被更改，因此 _FillValue 仍然是 'b''

- 处理级别：Argo 数据通过卫星传输接收，在国家数据汇编中心（DACs）解码和组装。这些 DACs 对数据应用一组自动质量测试（RTQC），并相应地分配质量标志。在延迟模式过程中（DMQC），数据将接受视觉检查，并在必要时重新分配质量标志。对于受传感器漂移影响的浮标数据，当需要时，使用统计工具和气候比较来调整数据以补偿传感器漂移。对于每个在延迟模式下处理过的浮标，将运行 OWC 方法（Owens 和 Wong，2009；Cabanes 等人，2016），使用四个不同的空间和时间去相关性尺度以及最新的可用参考数据集。如果从四个运行中获得的所有盐度调整都显著不同于现有调整，则将重新检查浮标的盐度数据，并在必要时提出新的调整。通常的做法是在收集后约12个月首先检查延迟模式下的剖面，然后随着从浮标获得更多数据，多次回顾（详见 Wong 等人，2020 年）。
