summary: The 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.).
acknowledgment: The UHSLC Fast Delivery database is supported by the National Oceanic and Atmospheric Administration (NOAA) Office of Climate Observations (OCO).

_FillValue: 0.000000000000000
long_name: date of last Research Quality sea level value
comment: Values in last_rq_date correspond to an identical value in the time vector. Dates less than or equal to last_rq_date for a given station correspond to Research Quality (RQ) data. Dates after last_rq_date correspond to Fast Delivery (FD) data. Missing values indicate no RQ data for a station.
