A radiosonde is a meteorological instrument which, launched under a balloon, measures parameters such as pressure, temperature, humidity and wind (direction, velocity) in the atmosphere and transmits data to the ground.
The M10 is the Meteomodem latest generation of radiosonde, operated numerous National Meteorological Services for their upper air station network, in the world (more than 120 systems in almost 60 countries).
The M10 allows to transmit PTU (Pressure, Temperature, Humidity) and wind data (speed and direction) in real time by radio telemetry. The data are collected then processed and analysed by our software suite allowing the automatic generation and transmission of WMO and Military Format messages.
Pressure is calculated from the GNSS (GPS and/or GLONASS) altitude (Concept introduced by Meteomodem). This WMO recognized and recommended method M10 through the 77 code. The M10 is currently in GRUAN certification, in cooperation with Météo France also committed for its Reunion Island and Trappes Sites.
