This document provides a documentation of the NFDI4Earth software architecture. The documen-tation summarizes the major user cases, gives an overview on the requirement analysis approaches for the main NFDI4Earth software components, points out envisioned quality goals and potential architecture’s stakeholders. Getting more specific, the documentation provides externally and in-ternally driven constraints that need to be considered when developing or contributing to NFDI4Earth software components. We herewith facilitate, the users to better understand the solu-tion strategy for the NFDI4Earth architecture. We use the arc42 template for the documentation of software and system architecture. The detailed description of the NFDI4Earth architecture is done by using a blackbox-whitebox approach that describes the major aim, the main functionalities and interfaces of the components as seen by the users first (blackbox) and then provides details on the (inner) solutions, e.g., sub-components, im-plementations (whitebox). The envisioned target group of the documentation includes software developers and architects as well service providers.
