ETSI ETSI EN 302 054 V2.1.1 (2017-10) 6 Introduction Meteorological aids, Radiosondes, are light weight, disposable precision measurement instruments mainly used for in situ upper air measurements of meteorological variables (pressure, temperature, relative humidity, wind speed and direction) in the atmosphere up to an altitude of 36 km. The measurements are vital to international weather forecasting capability (and hence severe weather warning services for the public involving protection of life and property). The Radiosonde systems provide simultaneous measurements of the vertical profile of temperature, relative humidity as well as wind speed and direction. The variation of these meteorological variables in the vertical contains the majority of the critical information for weather forecasting. These systems are the only meteorological observing systems able to regularly provide the vertical resolution that meteorologists need for all five variables (i.e. pressure, temperature, relative humidity, wind speed and direction). Typically the Radiosonde observations are produced by Radiosondes measuring atmosphere for approximately 2 hours and carried by ascending balloons launched from land stations or ships. Radiosonde observations are carried out routinely by almost all countries, two to four times a day. The observation data is then circulated immediately to all other countries within a few hours via the WMO (World Meteorological Organization) Global Telecommunications System (GTS). The observing systems and data dissemination are all organized under the framework of the World Weather Watch Programme of WMO. The observation stations are required, worldwide, at a horizontal spacing of less than or equal to 250 km with a frequency of observation from one to four times per day.
Remotely sensed measurements from satellites do not have the vertical resolution available from Radiosondes. Successful derivation of vertical temperature structure from these satellite measurements usually requires a computation initialized either directly from Radiosonde statistics or from the numerical weather forecast itself. In the latter case, the Radiosonde measurements ensure that the vertical structure in these forecasts remains accurate and stable with time. In addition, the Radiosonde measurements are used to calibrate satellite observations by a variety of techniques. Radiosonde observations are thus seen to remain absolutely necessary for meteorological operations for the foreseeable future. Other applications, independent of the main civilian meteorological organizations include environmental pollution, hydrology, radioactivity in the free atmosphere, significant weather phenomena (e.g. winter storms, thunderstorms, etc.) and investigation of a range of physical and chemical properties of the atmosphere.
About 150 000 Radiosondes are annually used in Europe, about 90 % of them are in 403 MHz band. This use is not decreasing with time, since with modern automation it is now much easier to successfully operate systems without highly skilled operators and a large amount of supporting equipment. The Radiosondes use unidirectional transmission on two frequency bands: 403 MHz band covers primary and co-primary allocations from 400,15 MHz to 406 MHz and 1 680 MHz band from 1 668,4 MHz to 1 690 MHz. The 403 MHz Radiosonde technology applies GNSS (Global Navigation Satellite Systems) for wind measurement, whereas the 1 680 MHz systems may base the wind measurement on balloon tracking with a Radio Direction Finding antenna. Because the 403 MHz wind measurement depends on the availability of the GNSS signals, many operators do not consider this technology secure enough for critical applications (e.g. defence and national security), and consequently prefer 1 680 MHz systems. National regulatory conditions (channel/frequency separations or the inclusion of an automatic transmitter shut-off feature) for an individual/general license or license exemption may apply.

Introduction
Meteorological aids, Radiosondes, are light weight, disposable precision measurement instruments mainly used for
in situ upper air measurements of meteorological variables (pressure, temperature, relative humidity, wind speed and
direction) in the atmosphere up to an altitude of 36 km. The measurements are vital to international weather forecasting
capability (and hence severe weather warning services for the public involving protection of life and property). The
Radiosonde systems provide simultaneous measurements of the vertical profile of temperature, relative humidity as well
as wind speed and direction. The variation of these meteorological variables in the vertical contains the majority of the
critical information for weather forecasting. These systems are the only meteorological observing systems able to
regularly provide the vertical resolution that meteorologists need for all five variables (i.e. pressure, temperature,
relative humidity, wind speed and direction).
Typically the Radiosonde observations are produced by Radiosondes measuring atmosphere for approximately 2 hours
and carried by ascending balloons launched from land stations or ships. Radiosonde observations are carried out
routinely by almost all countries, two to four times a day. The observation data is then circulated immediately to all
other countries within a few hours via the WMO (World Meteorological Organization) Global Telecommunications
System (GTS). The observing systems and data dissemination are all organized under the framework of the World
Weather Watch Programme of WMO.
The observation stations are required, worldwide, at a horizontal spacing of less than or equal to 250 km with a
frequency of observation from one to four times per day.
Remotely sensed measurements from satellites do not have the vertical resolution available from Radiosondes.
Successful derivation of vertical temperature structure from these satellite measurements usually requires a computation
initialized either directly from Radiosonde statistics or from the numerical weather forecast itself. In the latter case, the
Radiosonde measurements ensure that the vertical structure in these forecasts remains accurate and stable with time. In
addition, the Radiosonde measurements are used to calibrate satellite observations by a variety of techniques.
Radiosonde observations are thus seen to remain absolutely necessary for meteorological operations for the foreseeable
future.
Other applications, independent of the main civilian meteorological organizations include environmental pollution,
hydrology, radioactivity in the free atmosphere, significant weather phenomena (e.g. winter storms, thunderstorms, etc.)
and investigation of a range of physical and chemical properties of the atmosphere.
About 150 000 Radiosondes are annually used in Europe, about 90 % of them are in 403 MHz band. This use is not
decreasing with time, since with modern automation it is now much easier to successfully operate systems without
highly skilled operators and a large amount of supporting equipment.
The Radiosondes use unidirectional transmission on two frequency bands: 403 MHz band covers primary and
co-primary allocations from 400,15 MHz to 406 MHz and 1 680 MHz band from 1 668,4 MHz to 1 690 MHz. The
403 MHz Radiosonde technology applies GNSS (Global Navigation Satellite Systems) for wind measurement, whereas
the 1 680 MHz systems may base the wind measurement on balloon tracking with a Radio Direction Finding antenna.
Because the 403 MHz wind measurement depends on the availability of the GNSS signals, many operators do not
consider this technology secure enough for critical applications (e.g. defence and national security), and consequently
prefer 1 680 MHz systems.
National regulatory conditions (channel/frequency separations or the inclusion of an automatic transmitter shut-off
feature) for an individual/general license or license exemption may apply.
