Argo float vertical profile R4903258_036

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).

本数据集收录了由 Argo S2A 浮标在特定经纬度和日期下，从海面至 2000 米深度所测量的海洋剖面数据。数据中包含了以 1 米为间隔的压力、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 月进行了延迟模式的质量控制，并提交至全球数据汇编中心（GDACs）。所有可用的剖面数据计划在 2021 年初进行回访和评估。浮标编号 4903233 在剖面编号 77 时开始出现盐度漂移，盐度数据将在 2021 年初进行仔细检查并做出新的调整。

- processing_level: Argo 数据通过卫星传输接收，并在国家数据汇编中心（DACs）进行解码和组装。这些 DACs 对数据应用一系列自动质量测试（RTQC），并相应地分配质量标志。在延迟模式处理（DMQC）中，数据将接受视觉检查，并在必要时重新标记。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，使用 OWC 方法（Owens 和 Wong，2009；Cabanes 等人，2016）与四组不同的空间和时间去相关尺度以及最新的可用参考数据集一起运行。如果从四次运行中获得的所有盐度调整与现有调整差异显著，则将重新审查浮标上的盐度数据，并在必要时提出新的调整建议。通常的做法是在收集后大约 12 个月后首先检查延迟模式下的剖面，然后随着更多浮标数据的获取而多次回访（详见 Wong 等人，2020 年）。
