This report presents the implementation of the FAIR principles across the atmospheric subdomain over the ENVRI-FAIR project period. The report starts with the introduction and background for the baseline for the FAIR implementation of the atmospheric subdomain. Subsequently, the progress, achievements, and status of FAIRness within the atmospheric subdomain is described in 2 levels. Section 2.1 documents the progress and FAIRness in accordance with the implementation plan, whereas section 2.2 reports a summary and assessment of the FAIR implementation Profile (FIP), including FAIR convergence within the atmospheric subdomain. A section comparing the atmospheric sub-domain with all the environmental domain is also included. The final section 3 gives a summary of the main achievements for the atmospheric subdomain and highlights what can be done now compared to the start of the work in 2019.
