5G Is Likely to Put Weather Forecasting at Risk

Losing faint but reliable water vapor signals in a sea of 5G noise is the essential problem facing weather forecasters, and it’s one they’ve faced before. The signals turned out to be reflections from geosynchronous direct TV satellites, bouncing off the surface and swamping the water vapor signals the weather satellites were trying to measure. The water vapor data returned by microwave radiometers like the Advanced Microwave Sounding Unit (AMSU) aboard a number of weather satellites is estimated to reduce the error of weather forecasts by 17%, the largest contributor by far among a group of dozens of other modalities.
