UHSLC Fast Delivery Tide Gauge Data (hourly)

Sea Surface Height

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.
