Hourly wave and sea-level measurements are available in ASCII files with filename format “yyyy-mm-dd_mobims-_cala_millor_scb- awac00X.wap” (yyyy-mm-dd according to the registration date, with 00X being the ID number of the instrument deployed). Each ASCII “*.wap” file is accompanied with the corresponding data header file (“*.hdr” extension) that contains all the information related to the instrument deployment, measuring parameters and details of the data contained in the “*.wap” files. The wave and sea-level dataset spans from 2011/05/20 up to the present day, except for a gap from 2019/05/20 to 2019/10/29 due to an instrument failure.
