>Not widely publicized is that 5G cellular is going to eliminate one of the primary data inputs that have made weather prediction successful.
When you say 5G, do you mean actual 5G in general or are you talking about mmWave (FR2, sometimes called 5G high band vs low band)? It's been frustrating having these things get mixed up, because the 5G standard has a lot of improvements aimed at more efficient spectrum utilization, further reduced latency, and other changes across a unified massive range of frequencies compared to previous standards. It should be quite useful therefore for existing spectrum as well, just as WiFi 6 brings improvements to 2.4 GHz utilization. T-Mobile for example has said its initial plans for 5G include using its 600 MHz spectrum, with mid-band and mmWave going to certain urban areas.
For whatever reason though most media and even tech people often incorrectly use 5G interchangeably with mmWave, and since 5G itself has plenty of changes it's not always clear what aspects someone is worried about. I assume in this case it's specific frequency blocks of mmWave that would be the interference concern, but I honestly don't know enough about the weather sources to be sure of that vs some other change to modulation causing more out of band interference or something like that.
