radio + French sonde, sounding line (from Old French, from Old English sund(rāp), sounding (line), from sund, sea).


  • David, a radiosonde is a type of probe containing meteorological instruments that transmits data that can be recorded remotely.

  • Attached to the balloon is a weather instrument called a radiosonde, which transmits data on temperature, humidity, and pressure at different layers through the atmosphere. operates 92 stations that launch balloons twice a day. with the closest station in Buffalo

  • The radiosonde is a small box filled with devices that measure atmospheric parameters as the balloon ascends; this device transmits the information to a computer via radio waves. News

  • The radiosonde data from Boulder, with two satellite data sets.

    Hot Water and Air

  • Even Paltridge et al. 2009, which relied on the NCEP reanalysis data, recognized that “[i]t is accepted that radiosonde-derived humidity data must be treated with great caution, particularly at altitudes above the 500 hPa [hectopascal] pressure level.”

  • Figure 4 shows the radiosonde water vapor data set from Boulder, which to my knowledge is the longest such record, together with various satellite records.

    Hot Water and Air

  • Cooling of the lower stratosphere (about 49,000-79,500ft.) since 1979 is shown by both satellite Microwave Sounding Unit and radiosonde data, but is larger in the radiosonde data.

    Global warming frequently asked questions

  • Recent analyses of temperature trends in the lower and mid - troposphere (between about 2,500 and 26,000 ft.) using both satellite and radiosonde (weather balloon) data show warming rates that are similar to those observed for surface air temperatures.

    Global warming frequently asked questions

  • * Since the late 1950s, all radiosonde data sets show that the low and mid troposphere have warmed as a rate slightly faster than the rate of warming at the surface.


  • For example, in meteorology bad ASOS and radiosonde observations sometimes make it into models, and good ones are sometimes erroneously rejected.
