Twice a day, everyday, National Weather Service offices across the country launch weather balloons into the sky. The balloons carry an instrument called a radiosonde, which measures everything from temperatures and relative humidity, to wind speed at every level of the atmosphere.
After sampling data in the atmosphere, weather balloons fall back to the ground. They can land anywhere, from open fields to residential areas, all depending on their wind driven flight. Those who find weather balloons are asked to return them to their local National Weather Service Office.
Tuesday, the National Weather Service in Lincoln, IL launched a balloon prior to daybreak. High winds in the highest levels of the atmosphere transported the balloon far to the east over the state of Indiana.
The occurrence of a balloon getting carried to the east is not extremely rare. However, the exact location of this balloons landing spot is fairly remarkable. The weather balloon landed over 160 miles east of Lincoln, at Indianapolis International Airport, right where the National Weather Service Office in Indianapolis is located. Talk about a perfect landing!
