Meteorologists Worry 5G Expansion Could Interfere With Weather Forecasts
As FCC seeks more radio frequencies to support new technology, some worry signals could bleed into satellite readings used to predict hurricanes

The Trump Administrations swift-moving plan to promote 5G networks is running into resistance from the weather-forecasting community.
The dispute centers around ultrahigh radio frequencies that the Federal Communications Commission recently auctioned off for use in the countrys next-generation wireless networks. Officials at other agencies, including the Department of Commerce and National Aeronautics and Space Administration, warn that those airwavesspecifically those above 24 gigahertzcould scramble nearby readings...

Perhaps the meteorologists are looking for a good excuse for when they screw up.

(17,493 posts)I read a prediction that once we had weather satellites in orbit we would be able to accurately predict the weather for at least a month in advance.
Obviously weather is far more complicated than was understood at that time and I doubt that we fully grasp weather science today.
Still the satellites did help and so did super computers. Better satellites and faster computers may still help but our knowledge of the factors that can influence weather might be the most important item.

(2,435 posts)In this administration the FCC is in bed with the big businesses. Frequencies above 20 Ghz are used for short range high detail radar, along with satellite communications. These spectrum allocations have been in place for decades.
Essentially, the Republican FCC sold off a bunch of frequencies to the telecommunications industry so their buddies could make even more money at the expense of the saftey of the common folk.

5G NETWORKS COULD THROW WEATHER FORECASTING INTO CHAOS
IF YOU HAD a choice between a better, faster cell phone signal and an accurate weather forecast, which would you pick? Thats the question facing federal officials as they decide whether to auction off more of the wireless spectrum or heed meteorologists who say that such a move could throw US weather forecasting into chaos.
On Capitol Hill Thursday, NOAAs acting chief, Neil Jacobs, said that interference from 5G wireless phones could reduce the accuracy of forecasts by 30 percent. That's equivalent, he said, to the quality of weather predictions four decades ago. If you look back in time to see when our forecast scale was roughly 30 percent less than today, it was 1980, Jacobs told the House Subcommittee on the Environment.
That reduction would give coastal residents two or three fewer days to prepare for a hurricane, and it could lead to incorrect predictions of the storms final path to land, Jacobs said. This is really important, he told ranking committee member Frank Lucas (R-Oklahoma).
In March, the FCC began auctioning off its 24-gigahertz frequency band to wireless carriers, despite the objections of scientists at NOAA, NASA, and the American Meteorological Society. This week, Senators Ron Wyden (D-Oregon) and Maria Cantwell (D-Washington) wroteto FCC chair Ajit Pai requesting the commission stop companies from using the 24-GHz band until a solution is found, and to delay any more of the auction.
Jordan Gerth, a research meteorologist at the University of Wisconsin, Madison, has been studying this issue as part of a group at the American Meteorological Society. He says that while the FCC can switch which regions of the spectrum it allocates to phone companies, forecasters are stuck. Thats because water vapor emits a faint signal in the atmosphere at a frequency (23.8 GHz) that is extremely close to the one sold for next-generation 5G wireless communications (24 GHz). Satellites like NOAA's GOES-R and the European MetOp monitor this frequency to collect data that is fed into prediction models for upcoming storms and weather systems.
