The goal of the web portal and the data archive is the provision of "easy-to use" data. Therefore the SAMD Product Standard has developed to ensure that data from the multitude of instrument types can be used in a uniform manner. All data are stored in NetCDF format, with the usage of CF-conventions (Climate Forecast), as possible, which are well known in the model community and an important condition for the easy appropriability for all users, independent on previous experience with measurement data. The Data Product Standard includes the conventions for the file naming, for the unambiguous assignment for each data set, NetCDF conventions, as file header and variable names, and of standardized meta-data (XML) for each data set (XML-editor). The document is maintained and broadened continuously, and is applicable not only for measurement data of HD(CP)², but for also for upcoming campaigns and projects.
With the SAMD Product Standard (DOI: 10.5281/zenodo.1741364), we have developed the basis of an archive of standardized data sets, for the first time in Germany, and for this large multitude of instrument types.
