UHSLC Tide Gauge Dataset Metadata: Licence, Variables and Time Coverage (University of Hawaii)

uhslcerddap/dataset-metadata

The metadata of one University of Hawaii Sea Level Center tide gauge dataset on its ERDDAP server (daily or hourly, Fast Delivery or Research Quality): title, summary, licence, acknowledgement, creator, time coverage and the attributes of every variable (sea level in millimetres, time, quality level, station id, position, reference datum). Pass the dataset id to the other UHSLC tools. The dataset is one of four whose licence was read; the id is checked against that list before any call. The data may be used and redistributed but is not intended for legal use, since it may contain inaccuracies. Data from the University of Hawaii Sea Level Center, passed through unmodified and served by Eden Engine; not an official UHSLC product.
