The Upper Air measurements
Upper Air Observation also called Radiosounding is the only in-situ measurement process performed in the Upper Air (from ground to approx. 30 km). The radiosonde consists of an airborne device equipped with a set of sensors, that is released into the atmosphere under a latex balloon. The ascent usually lasts between one and two hours and allows to draw a vertical profile of the atmosphere. These soundings are called PTU-W type, because it measures the following physical parameters: P (pressure), T (temperature), U (humidity), as well as the parameter WF (wind force) and WD (wind direction). The data is sent by radiotelemetry to the ground and processing station. Sometimes specific sensors are added (stratospheric ozone measurements, for example).
By extension, the term radiosonde also refers to all the launching operations, the follow-up of the sonde as well as the display in real-time or again the dissemination of the results.
SR20
The new Meteomodem receiver: more powerful, more robust, and designed to meet the sector's most demanding requirements. Fully compatible with the entire Meteomodem range, it guarantees simple, efficient integration into your existing installations. Whether for mobile or stationary operations, it offers optimum reliability, even in the most demanding environments.
M20
Report of WMO’s 2022 Upper-Air Instrument Intercomparison Campaign
Meteomodem actively participated in the international UAII campaign, demonstrating the efficiency and reliability of its M20 radiosonde.
The results highlighted the M20’s measurement accuracy and robustness across a variety of operating environments.
This participation reaffirms Meteomodem’s commitment to the continuous improvement of its instruments and its contribution to the quality standards of the GRUAN network.
