5G signal could jam weather forecasting satellites

“The way 5G is being introduced could seriously compromise our ability to forecast major storms,” said Tony McNally of the European Centre for Medium-Range Weather Forecasts in Reading. “In the end it could make the difference between life and death. We are very concerned about this.”

The crisis facing the world’s meteorologists stems from the fact that the radio frequencies the new 5G networks will use could contaminate critical Earth observations made by weather satellites.

Instruments on board the satellites peer down into the atmosphere and study variables such as water vapour, rain, snow, cloud cover and ice content – all crucial factors that influence our weather.

One example is the 23.8 gigahertz (GHz) frequency. Water vapour emits a faint signal at this specific natural wavelength, and this data is monitored and measured by weather satellites. Forecasters then use this information to work out how a storm or weather system is likely to develop.

“Such data is critical to our ability to make forecasts,” said Niels Bormann, also of the Reading weather centre. “They are a unique natural resource, and if we lose this capability, weather forecasts will get significantly worse.”

The urgency of the problem is underlined by the fact that US Federal Communications Commission and similar agencies in other countries have already started to auction off frequencies close to the 23.8 GHz frequency to future 5G network providers. In addition, other bands that are used to probe our weather include the 36-37 GHz band, which is used to study rain and snow; the 50 GHz band, which is used to measure atmospheric temperature; and the 86-92 Ghz band, which helps to analyse cloud and ice.

All these contain sections of waveband that are being auctioned off in the US. It remains to be seen if other nations will follow suit and sell these frequencies in their own countries over coming months.

“The more we lose, the greater the impact will be,” states meteorologist Jordan Gerth, of the University of Wisconsin-Madison, in the current issue of Nature. “This is a global problem.”

According to the weather maps I’ll be warmer staying here in BC than if I drove/flew 1,900 south to Graceland.

To convert Celsius to Fahrenheit temperatures:

     

  1. Take the temperature in Celsius and multiply 1.8.

  2. Add 32 degrees.

  3. The result is degrees Fahrenheit.
