Atmospheric Models are a relevant element of Climate Research. Access to this atmospheric model data is not only of interest to a wide scientific community but also to public services, companies, politicians and citizens. The state-of-the-art approach to make the data available is to publish them via a data repository that adheres to the FAIR (Findable, Accessible, Interoperable, and Reusable) principles(1). A FAIR publication of research data implies that the data are described with rich metadata and that the data and metadata meet relevant discipline-specific standards. 

A very comprehensive data standard has been developed for the climate model output within the Climate Model Intercomparison Project (CMIP)(2), which largely builds upon the Climate and Forecast Metadata Conventions (CF Conventions)(3). Nevertheless, there are many areas of atmospheric modelling, where data standardisation according to the CMIP standard is not possible or very difficult. To facilitate this task, the ATMODAT standard(4), a quality guideline for the FAIR and open publication of atmospheric model data, was recently established. 

The ATMODAT standard defines a set of requirements that aim at ensuring a high degree of reusability of published atmospheric model data. The requirements include the use of the netCDF file format(5), the application of the CF conventions(3), a data publication with a DataCite DOI(6), and rich and standardised metadata for the data files, the DOI and on the landing page. 

The atmodat data checker(7) was developed to support data producers in checking if their file metadata comply with the ATMODAT standard. 

We demonstrate the application of the ATMODAT standard to selected datasets from a building-resolving atmospheric model, the "grassroots" AEROCOM MIP, and weather pattern data derived from an atmospheric reanalysis. We explain the practical workflow involved to achieve an ATMODAT-compliant data publication and discuss the various challenges.
