Global Temperature and Salinity Profile Programme (GTSPP) Data, 1985-present

The Global Temperature-Salinity Profile Programme (GTSPP) develops and maintains a global ocean temperature and salinity resource with data that are both up-to-date and of the highest quality. It is a joint World Meteorological Organization (WMO) and Intergovernmental Oceanographic Commission (IOC) program. It includes data from XBTs, CTDs, moored and drifting buoys, and PALACE floats. For information about organizations contributing data to GTSPP, see http://gosic.org/goos/GTSPP-data-flow.htm . The U.S. National Oceanographic Data Center (NODC) maintains the GTSPP Continuously Managed Data Base and releases new 'best-copy' data once per month.

WARNING: This dataset has a *lot* of data. If you request too much data, your request will fail.
* If you don't specify a longitude and latitude bounding box, don't request more than a month's data at a time.
* If you do specify a longitude and latitude bounding box, you can request data for a proportionally longer time period.
Requesting data for a specific station_id may be slow, but it works.

*** This ERDDAP dataset has data for the entire world for all available times (currently, up to and including the September 2024 data) but is a subset of the original NODC 'best-copy' data. It only includes data where the quality flags indicate the data is 1=CORRECT, 2=PROBABLY GOOD, or 5=MODIFIED. It does not include some of the metadata, any of the history data, or any of the quality flag data of the original dataset. You can always get the complete, up-to-date dataset (and additional, near-real-time data) from the source: https://www.nodc.noaa.gov/GTSPP/ . Specific differences are:
* Profiles with a position_quality_flag or a time_quality_flag other than 1|2|5 were removed.
* Rows with a depth (z) value less than -0.4 or greater than 10000 or a z_variable_quality_flag other than 1|2|5 were removed.
* Temperature values less than -4 or greater than 40 or with a temperature_quality_flag other than 1|2|5 were set to NaN.
* Salinity values less than 0 or greater than 41 or with a salinity_quality_flag other than 1|2|5 were set to NaN.
* Time values were converted from "days since 1900-01-01 00:00:00" to "seconds since 1970-01-01T00:00:00".

全球温度-盐度剖面计划（GTSPP）致力于开发和维护一个全球海洋温度和盐度资源库，该资源库中的数据既更新及时，又具备极高的质量标准。该计划由世界气象组织（WMO）和政府间海洋学委员会（IOC）共同发起。其数据来源包括XBT、CTD、锚定和漂流浮标，以及PALACE浮标。有关向GTSPP贡献数据的组织信息，请参阅http://gosic.org/goos/GTSPP-data-flow.htm。美国国家海洋数据中心（NODC）负责维护GTSPP的持续管理数据库，并每月发布一次新的'最佳副本'数据。

警告：该数据集包含大量数据。若请求数据量过大，您的请求将失败。
* 若未指定经纬度边界框，每次请求的数据量不超过一个月。
* 若指定了经纬度边界框，则可请求较长时间段内的数据。
请求特定站点的数据可能较慢，但可行。

*** 该ERDDAP数据集包含全球所有可获取时间（目前为截至2024年9月的数据）的数据，但它是原始NODC'最佳副本'数据的一个子集。它仅包括质量标志指示数据为1=正确、2=可能良好或5=修改的数据。它不包括某些元数据、任何历史数据或原始数据集中的任何质量标志数据。您始终可以从源头获取完整、最新的数据集（以及额外的近实时数据）：https://www.nodc.noaa.gov/GTSPP/。具体差异如下：
* 移除了位置质量标志或时间质量标志不是1|2|5的剖面。
* 移除了深度（z）值小于-0.4或大于10000，或z_variable_quality_flag不是1|2|5的行。
* 温度值小于-4或大于40，或温度质量标志不是1|2|5的设置为NaN。
* 盐度值小于0或大于41，或盐度质量标志不是1|2|5的设置为NaN。
* 时间值从“自1900-01-01 00:00:00以来的天数”转换为“自1970-01-01T00:00:00以来的秒数”。

有关质量标志的定义，请参阅https://www.nodc.noaa.gov/GTSPP/document/qcmans/GTSPP_RT_QC_Manual_20090916.pdf页面第5页的“表2.1：全球不可能的参数值”以及https://www.nodc.noaa.gov/GTSPP/document/qcmans/qcflags.htm的质量标志定义。
