ClimEx high frequency sea level observations from low-cost pressure sensors at Blancs Sablons (Le Conquet, France)
The dataset consists of raw pressure data and sea level data from 27 low-cost bottom pressure sensors (Mastodon probes) sampling at 2 Hz. The low-cost sensors were deployed at Blancs Sablons (Le Conquet, France) during more than 4 months, from 14 December 2023 to 25 April 2024. The coordinate files (coord_sensors.txt) contains the longitude and latitude of the 27 sensors. The RAW_PRESSURE_DATA directory contains 27 files in text format (csv). The pressure files (climex_blancs_sablons_M*_P.csv) contain a header (10 lines), and then one line per time record (every 0.5 s), with the date, the temperature (°C), and the pressure (bar). The SEA_LEVEL_DATA directory contains 27 files in NetCdf format (climex_blancs_sablons_M*_sea_level.nc). The ’sea_level’ variable is expressed in meters and related to Chart Datum. The ’time’ variable is expressed in seconds and represents the number of elapsed days since 1970-01-01 00:00:00 UTC.
