"It's like state-sanctioned littering,"Mr Furphy said.
"But that day we went out we found two of these meteorological measuring devices, which is quite extraordinary."
"That's when they finally burst and fall back to Earth."
"Clouds have a huge impact on warming and cooling of the Earth's surface, which impacts everything from long-term climate to short-term weather,"Mr Powers said.
"The trade-off is that the measurements and the impact on people's quality of life and people's safety by knowing what the weather is, are absolutely important and that's part of the trade-off equation."
