This paper identifies and provides access to relevant real-world open datasets that can be used to develop AI-enabled radio resource management solutions for NTNs. The key highlights are:

Potential use cases for NTNs are explored, including maritime, public protection and disaster relief (PPDR), and direct-to-smartphone scenarios. Corresponding open datasets are identified and guidelines for their utilization are provided.
The maritime use case dataset offers realistic marine traffic information that can be used for traffic forecasting, resource scheduling, and adaptive beamforming. The PPDR use case leverages the Ookla global network performance dataset to identify underserved areas where NTN resources are critically required.
For the direct-to-smartphone use case, the paper proposes an integration of the Ookla and Meta AI datasets to estimate the population density and network performance in remote areas, enabling the design of an AI-based adaptive beamforming system to serve the user demand.
The paper also provides realistic user traffic patterns (UTPs) for different use cases, which can be combined with the identified datasets to enable comprehensive resource management optimization.
An example of utilizing the integrated dataset for beamforming in the direct-to-smartphone use case is presented, demonstrating how the available information can be leveraged to project a beam from the satellite to serve the users in the identified underserved regions.

The provided datasets and guidelines aim to inspire and assist the research community in developing advanced resource management solutions for NTNs, leveraging the power of AI techniques.
