Pressure measurements on the Tête Rousse glacier

This dataset contains the water pressure measurements (in meter of elevation of the water level in NGF IGN 69) for all piezometers installed in the Tête Rousse glacier since 2010. The file Data_All_Piezo.csv gives for each piezo number (piezo_id), the drill depth (drill_depth in m), the starting date (start date) and the ending date (end_date) if the piezo is not working anymore, the x and y coordinate of the drill (x_lat, y_lon in meter Lambert 2), the elevation of the surface (zs_m in meter NGF IGN 69), the date at which this elevation was measured (date_zs), the altitude of the piezometer (zpiezo_m in meter NGF IGN 69), the reference altitude to compute the water level (zref_m in meter NGF IGN 69) and the type of measurement (type_measurement either 'Profondeur' - depth or 'Niveau' - level) For each piezometer, a csv file of the form 'piezo'+piezo_id+'.csv' containing the date (date in UTC) and the water level (Niv in meter NGF IGN 69). Version v2: update with 2023 measurements for piezo 69, 191, 2206 and 2207. Update of Data_All_Piezo.csv file Version v3: update with 2024 measurements for piezo 69 and 191 and add piezo 2403, 2406 and 2410. Update of Data_All_Piezo.csv file Version v4: update with 2025 measurements for piezo 191, 2206, 2403, 2406, 2410 and add piezo 2501 and 2508. Update of Data_All_Piezo.csv file
