UHSLC Fast Delivery Tide Gauge Data (daily)

The University of Hawaii Sea Level Center (UHSLC) assembles and distributes the Fast Delivery (FD) dataset of hourly- and daily-averaged tide gauge water-level observations. Tide gauge operators, or data creators, provide FD data to UHSLC after a level 1 quality assessment (see processing_level attribute). The UHSLC provides an independent quality assessment of the time series and makes FD data available within 4-6 weeks of collection. This is a "fast" turnaround time compared to Research Quality (RQ) data, which are available on an annual cycle after a level 2 quality assessment. RQ data replace FD data in the data stream as the former becomes available. This file contains hybrid time series composed of RQ data when available with FD data appended to the end of each RQ series.

processing_level=Fast Delivery (FD) data undergo a level 1 quality assessment (e.g., unit and timing evaluation, outlier detection, combination of multiple channels into a primary channel, etc.). In this file, FD data are appended to Research Quality (RQ) data that have received a level 2 quality assessment (e.g., tide gauge datum evaluation, assessment of level ties to tide gauge benchmarks, comparison with nearby stations, etc.).

夏威夷大学海平面研究中心（UHSLC）汇编并分发每小时及每日平均潮位观测的快速交付（FD）数据集。潮位观测员，或数据创建者，在完成一级质量评估（详见处理级别属性）后，向UHSLC提供FD数据。UHSLC对时间序列进行独立的质量评估，并在数据收集后4-6周内提供FD数据。相较于需经过二级质量评估、按年度周期提供的科研质量（RQ）数据，这一处理周期更为迅速。当RQ数据可用时，将替换数据流中的FD数据。此文件包含混合时间序列，其中当RQ数据可用时，FD数据将附加到每个RQ序列的末尾。
