Mobile-phone expansion could disrupt key weather satellites : Nature News & Comment - Jul 2016
"As Hurricane Patricia barrelled down on Mexico last October, forecasters at the US National Oceanic and Atmospheric Administration (NOAA) grabbed as many ­satellite images as they could to track its progress. But at least one crucial shot failed to download. A 22 October image from the ­Geostationary Operational Environ­mental Satellite (GOES) system showed a black swathe — no data — across most of the Pacific Ocean. . . . The culprit was radio interference from mobile-phone companies. And the problem may soon get worse."
"In a representative sample of GOES imagery taken between May and September 2015, the agency found that 3.6% of the data ­during that stream had been subject to interference. And in May of this year, NOAA clocked 30 events in which satellite transmissions had dropped out, either streaking or nearly obliterating the images. “We consider that to be unacceptable,” Wissman says."

How eight microsatellites could improve hurricane forecasts -
"The suitcase-sized satellites began moving off assembly tables earlier this month and are designed to estimate wind speeds in the core of a hurricane." "The craft are designed to use global-positioning-satellite signals, reflected off the sea surface, to measure surface roughness. Roughness is a surrogate for direct wind measurements."
