When did the National Weather Service Start upper air observations with radiosondes attached to weather balloons?
In the late 1920’s, scientists began suspending crude radio transmitters from free balloons and by the early 1930’s the first radio-meteorographs or “radiosondes” were being flown into the stratosphere. In 1937 the Weather Bureau established a network of radiosonde stations that has continued to the present day.
Why are weather balloons still used?
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 is the only real time upper air weather observation source?
Pilots also provide vital information regarding upper air weather observations and remain the only real-time source of information regarding turbulence, icing, and cloud heights. … Together, PIREPs and radiosonde observations provide information on upper air conditions important for flight planning.
Are radiosondes still used?
Radiosondes provide a primary source of upper-air data and will remain so into the foreseeable future.
What kind of radio do weather balloons carry?
A radiosonde is a battery-powered telemetry instrument carried into the atmosphere usually by a weather balloon that measures various atmospheric parameters and transmits them by radio to a ground receiver.
