The dataset contains the electrical resistivity tomography (ERT) monitoring data from the publication Wicki and Hauck (2022). It contains the unprocessed monitoring data and the filtered monitoring data prior to the inversion process. The data is organized in two zip-files: * Napf_Raw_BIN.zip: Raw monitoring data in bin-format * Napf_Filtered_DAT.zip: Filtered monitoring data in dat-format including topography of the monitoring line The zip files contain the apparent resistivity measurements (ohm m) of the individual measurements. The naming convention of the files is according to following convention: site_profile_configuration_date_time.format The file names contain following abbreviations: * Site: Napf * Profile: Hor (horizontal profile), Ver (vertical profile) * Configuration: WS (Wenner-Schlumberger configuration) * Date: Format YYYY-MM-DD * Time: Format hhmm
