Does NOAA use weather balloons?
Demonstration project underway as Alaska receives first autolaunch stations. NOAA’s National Weather Service is tapping technology to automate weather balloon launches in Alaska, a move that will allow staff to improve public service across the state while saving federal tax dollars.
Do we still use weather balloons?
Fast forward to today, the National Weather Service now has 92 sites where balloons are turned loose each day. “Weather balloons have gone through dozens of upgrades over the past 150 years. Radiosondes that used to weigh a few pounds are now just a few ounces. The balloons and strings are biodegradable.
What do I do if I find a weather balloon?
(1) Cut and discard the string to the burst balloon and orange parachute. IMPORTANT: On rare occasions the balloon may be found partially inflated with gas. The gas inside the balloon may be flammable hydrogen. If the balloon is inflated, keep away from it and contact your local fire department for safe disposal.
What kind of data does a weather balloon collect?
These observations include vertical profiles of temperature, humidity, wind speed and direction, atmospheric pressure, and geopotential height.
How far does a weather balloon travel?
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 have lights?
Weather balloons don’t have any flashing lights, but they are up to 20 feet in diameter and highly reflective. And they move relative to the stars, as you say you observed. Not surprisingly, these things often trigger UFO reports to police, airports, and military bases.
Do planes hit weather balloons?
A couple THOUSAND weather balloons are launched each day. Pilots and air traffic controllers are never warned about them, because the odds of a plane running into one are quite small and even if one does, it won’t damage the plane.
Do you need permission to launch a weather balloon?
No license is required to launch a balloon in the United States. However, it is critical that anyone planning a flight takes time to receive proper safety training.

Are weather balloons recovered?
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.
Who uses weather balloons?
Weather balloons are the primary source of data above the ground. They provide valuable input for computer forecast models, local data for meteorologists to make forecasts and predict storms, and data for research.

What to do if you find a weather balloon?
What to do if you find a weather balloon/radiosonde: (1) Cut and discard the string to the burst balloon and orange parachute. IMPORTANT: On rare occasions the balloon may be found partially inflated (2) Remove the plastic mailbag and seal the instrument inside the bag. NOTE: On the LMS-6 the
What does a weather balloon actually do?
A weather balloon (or sounding balloon) is a device that carries meteorological instrumentation into the atmosphere . It consists of a radiosonde attached to a balloon that measures temperature, humidity, air pressure, wind, and other data, which are sent back to a base station on Earth for analysis.
How does a weather balloon predict the weather?
While weather balloons may seem out-of-date by modern standards, agencies across the globe still rely on balloons to help predict the weather. These relatively simple devices carry gauges to capture information about wind, temperature and humidity levels, which meteorologists then use to draft your daily forecast.
Are weather balloons still used?
do they still use weather balloons? The balloons are used to measure temperature, pressure and humidity. They are filled with hydrogen gas and they soar up to 100-thousand feet in the sky. So weather balloons are definitely real and they while they are somewhat simple they are still considered the best way to measure atmospheric conditions.
