“The environmental and safety benefits of high-quality forecasts are significant.” The twice-a-day launches from 31 stations use helium- or hydrogen-filled balloons made of biodegradable, natural latex, which the department says will disappear harmlessly over time after the burst remains fall back to Earth.
Are weather balloons bad for the environment?
“All of those components can pose risks to our wildlife ” there’s batteries that we know are acidic, there are plastic components and the rubber balloon. “Balloons, in particular, are ingested by quite a lot of species like turtles; we have found so many of the components that are in the process of breaking up.“
Initially I was reassured that the balloons used would be biodegradable ones, but upon further research realized that all latex balloons are biodegradable, since they are comprised of a mix of organic compounds.
What happens to all the weather balloons?
Each radiosonde contains a mailing bag and instructions on what to do if you find one. About 20% of the 75,000 radiosondes sent up each year in the US are found and returned. These instruments are fixed and reused, saving the government money. Weather balloons are the primary source of data above the ground.
Those balloons often reach heights of 20 miles above Earth ” or twice as high as planes typically fly. Sensors beam data back down to Earth every few seconds as winds carry the balloons up to 125 miles away.

How long can a weather balloon stay in the air?
How long do high altitude weather balloons stay in flight? The average balloon will ascend for about 90 minutes before bursting. After the ascent is complete, the payload boxes and flight equipment will slowly fall on a parachute for around 30 minutes, giving the average flight a total duration of two hours.
Are weather balloons recoverable?
According to Weather Service, only 1 out of 5 radiosonde released are recovered. However, if you do find one, please return it because they can be reconditioned and used.
Where do weather balloons fly in the atmosphere?
The stratosphere is the next layer of the atmosphere. It extends anywhere from 4 to 12 miles (6 to 20 km) above Earth’s surface up to 31 miles (50 km). This is the layer where most commercial airliners fly and weather balloons travel to.
Do meteorologists use weather balloons?
Weather balloons are launched around the world for observations used to diagnose current conditions as well as by human forecasters and computer models for weather forecasting. Between 900 and 1,300 locations around the globe do routine releases, two or four times daily, usually at 0000 UTC and 1200 UTC.

Balloon sellers attempt to “promote latex balloons as 100% biodegradable and environmentally friendly”. They state it takes as long as an oak leaf, or “up to 6 months“.
Are sky lanterns biodegradable?
Sky Lanterns are basically small, translucent hot-air balloons. They have a small fuel source in the middle that, once lit, will lift the lantern slowly into the sky with a soft glow. These lanterns are made with fire-retardant, 100% biodegradable material.
Where are weather balloons launched Canada?
According to what a representative with Environment and Climate Change Canada told Buchanan, the radiosonde was launched from the Port Hardy upper air station on March 13, at 6:15 p.m. local time. It reached a height of 28,623 metres. Squamish meteorologist Jason Ross said it was an exciting discovery.

Each day, Environment Canada launches 62 weather balloons.
What to do if you find a radiosonde?
If the radiosonde is found after use, the person who discovers it can put it in the bag (no postage required) and give it to his/her mail carrier. The instrument is then sent to a reconditioning center so it can be reconditioned and reused. (Only about 15-20% of the instruments are ever found nationwide.
What is inside a radiosonde?
The radiosonde is a small instrument package that is suspended below balloon filled with either hydrogen or helium. As the radiosonde is carried aloft it measures pressure, temperature, and relative humidity.
How do they get the balloon to pop after 90 minutes?
As the air gets thinner, the balloon’s casing get tighter. This is due to the gas expanding within the balloon. The expanding gas causes the balloon to reach full capacity and it pops.
How far up can a weather balloon go?
Weather balloons can rise to an altitude of 24 miles (39 kilometers) or more before they burst, and a payload may land (via parachute) up to 75 miles (120 km) away, depending on wind conditions at the launch site, Maydell said.
Do weather balloons explode?
When the rubber balloons depart terra firma, they are around 5 feet wide. As they slowly climb above the clouds and high into the stratosphere, surrounding air pressure drops and the balloons expand. By the time one gets to 100,000 feet, the bulging orbs have grown to 30 feet across. And that’s when it happens ” POP!
