NOS CO-OPS Water Level Data, Tide Prediction, 6-Minute

This dataset has High Low Tide Predictions from NOAA NOS Center for Operational
Oceanographic Products and Services (CO-OPS).

The official Tide and Tidal Current prediction tables are published annually on
October 1, for the following calendar year. Tide and Tidal Current predictions
generated prior to the publishing date of the official tables are subject to
change. The enclosed data are based upon the latest information available as of
the date of your request. Tide and Tidal Current predictions generated may
differ from the official predictions if information for the station requested
has been updated since the publishing date of the official tables.

WARNING:
* Queries for data MUST include stationID=, time>= and time<=.
Queries MUST be for less than 30 days worth of data.
* This dataset only returns data for the MLLW (Mean Lower-Low Water) datum.
* The data source isn't completely reliable. If your request returns no data
when you think it should:
* Try revising the request (e.g., a different time range).
* The list of stations offering this data may be incorrect.
* Sometimes a station or the entire data service is unavailable.
Wait a while and try again.

本数据集收录了来自美国国家海洋和大气管理局（NOAA）海洋操作产品和服务中心（CO-OPS）的高潮低潮预测数据。
官方的潮汐与潮流预测表每年10月1日发布，适用于次年的日历年度。发布日期之前的潮汐与潮流预测数据可能会发生变化。所提供的数据基于您请求之日的最新信息。若请求的站点信息自官方表发布以来已更新，生成的潮汐与潮流预测可能与官方预测存在差异。
**警告：**
* 数据查询必须包含stationID=, time>= 和 time<= 参数。
* 查询的数据量应少于30天。
* 本数据集仅返回平均低潮位（MLLW）基准的数据。
* 数据来源可能并不完全可靠。若您认为应返回数据而实际未返回，请尝试以下操作：
* 修改请求（例如，更改时间范围）。
* 提供该数据的站点列表可能存在错误。
* 有时单个站点或整个数据服务可能不可用。请稍后重试。
