ATMODAT Standard Description

Within the AtMoDat project (Atmospheric Model Data), a standard has been developed which includes concrete recommendations  related to the maturity, publication and enhanced FAIRness of atmospheric model data published in repositories. Atmospheric model data form the basis to understand and predict natural events, including atmospheric circulation, local air quality pattern and the planetary energy budget. Such data should be made available for evaluation and reuse by scientists, the public sector, and relevant stakeholders. 

 

The suggestions include requirements for:

Specifications for Metadata

Metadata must describe the research data in such a way that the possible reusers are able to decide whether these data are useful for their application. Also, the process of the data generation and used input data must be documented. All necessary information can either be written directly into the metadata properties of the DataCite DOI or can be given by links to external documents – preferably via persistent identifiers (PIDs). Such an external document could e.g. be the documentation of the numerical model, that was used to calculate the data. It is strongly recommended that metadata are machine-readable so that they can be used to create automated lists, e.g. for evaluations of institutions. External documents should also be machine-readable. Read more


Specifications for the Landing Page

The ATMODAT standard contains instructions on how the human and machine readable parts of the landing page should be constructed and which metadata need to be included.

Specifications for File Formats and Standards

The ATMODAT Standard requires that

  • atmospheric modeling data are archived in netCDF files
  • netCDF file headers include description of time, coordinate and vertical axes according to Appendix E in the ATMODAT standard document.
  • netCDF headers also include a list of mandatory, recommended, and optional global attributes. The values of most of these attributes have to be taken from controlled vocabularies, see Appendix I in the ATMODAT standard document.
  • CF Conventions version 1.4 or higher are applied, see Appendix D in the ATMODAT standard document.

The CMIP6 standard requires a list of global attributes to be set in the netCDF files. The values of most of these attributes have to be taken from controlled vocabularies. In addition, the ATMODAT Standard specifies a list of mandatory, recommended, and optional global attributes based on the CMIP6 standard and other standards/conventions. Read more


Specifications for Licensing and Embargos of Published Data

As the reusability of data with restricted access is diminished, this should be avoided for atmospheric model data. Therefore, the ATMODAT Standard requires:

  • data to be published under a open license that is at least available in English language.
  • It is recommended to choose a license that is machine readable and use its standard name, if it is provided by SPDX (Software Package Data Exchange).
  • Additionally, an embargo is allowed but has to be limited in time. The length of the time period itself can be freely choosen but has to be publicly visible. Read more
