Nowadays, several of the most important scientific missions are based on the observation of atmospheric events. Monitoring the ozone layer, analyzing the effects of the climate change, or predicting natural disasters requires the creation of temperature or water vapor profiles that are typically generated through federated scientific instruments such as microwave radiometers. Geographically sparse federated radiometers analyze the electromagnetic power absorption of the atmosphere at different frequencies and transmit the results to computation centers (where maps and profiles are calculated) using broadband communications. Traditionally, mobile broadband communications and radiometers operate at different frequencies, and they do not interact. Microwave radiometers operate at the V band (40 – 75 GHz) and/or the K band (12 – 40 GHz), while old generations of mobile networks operate below 3 GHz. However, 5G New Radio access technologies may change that, as they may operate on frequencies from 24.25 GHz to 71.0 GHz. In this paper we analyze the interference between future 5G New Radio access technologies and microwave radiometers through numerical models and propose an orchestration mechanism to enable the coexistence between both infrastructures. The orchestration engine executes an intelligent time division multiple access algorithm to coordinate the use of the frequency spectrum, so the 5G network performance still meets the expected Quality-of-Service, measurements taken by radiometers are precise, and federated scientific services can operate normally. To validate the performance of the proposed mathematical framework, we implemented a simulation scenario using MATLAB. Our results show the proposed approach reduces interferences between 5G networks and scientific instruments up to 70%.
