ADCP moving ship measurements provide high-resolution insight into the hydrodynamics and sediment transport processes of a waterbody, thus improving the understanding of physical processes. In order to facilitate scientific advancement, the BAW provides ADCP data from a measurement campaign conducted in the Eider estuary in 2020. Data compliant with the FAIR principles can be downloaded from the BAW-Datenrepository. The raw and analysed data are available in ASCII format. Entering the ISO metadata and uploading the files is currently performed manually.
As an increasing number of data sets are to be published, the error-prone manual work is to be replaced by an automated workflow. In a first step, the raw data is converted into binary NetCDF files including metadata that complies with CF metadata conventions. The measurement and metadata are inseparable and consequently, the process is more error-proof. The existing ADCP2NETCDF converter has been extended for this purpose. Software that supports the generated CF NetCDF file type “trajectoryProfile” can process the offered files directly.
In a second processing step, it is planned to convert the NetCDF files into ISO-compliant metadata in XML format, which can be imported into the metadata information system (MIS) of the BAW-Datenrepository. A method that has already been successfully used for simulation data will be transferred to measurement data. The MIS already contains a metadata profile for measurements, these requirements have to be met by the generated XML files.
The automations described herein facilitate data entry and ensure the production of consistent results and quality-assured metadata.
