Quality & Value Through Innovation in Soundings

Vaisala radiosonde RS41

Vaisala radiosonde RS41

​The new Vaisala Radiosonde RS41 streamlines launch preparation for error-free performance and lowers operational costs of upper-air weather observations.


Vaisala Radiosonde RS92

Vaisala Radiosonde RS92

The Vaisala Radiosonde RS92 leads the modern era in sounding. It offers the world’s highest level of pressure, temperature and relative humidity measurement performance, and continuous wind data availability.


Ozone sounding with the Vaisala Radiosonde RS92

Ozone sounding with the Vaisala Radiosonde RS92

Ozone measurement is available for the 400 MHz digital Vaisala Radiosonde RS92-SGP. Two different ozone interface kits are available, RSA921 for ECC-type ozone sensors and RSA922 for Brewer-Mast type ozone sensor.


RS92 Add-on Interface

RS92 Add-on Interface

​The Vaisala DigiCORA® Sounding System with the Vaisala Radiosonde RS92 can be used to fly third party atmospheric in-situ research instruments and transfer the data for further analysis, together with the radiosonde information on height, wind, ambient temperature and humidity conditions.


Reference Radiosonde

Reference Radiosonde

I​n January 2009, Vaisala made a corporate commitment launching a program to develop an operational reference-grade radiosonde that could be used in GRUAN and other applications where enhanced radiosonde sensor performance is required.


Ozone Sounding with Radiosonde RS41-SG

Ozone Sounding with Radiosonde RS41-SG

With the Vaisala Ozone Interface OIF411, an ECC-type ozone sensor, and a digital RS41 radiosonde it is possible to measure pressure, temperature, humidity, and geopotential height, as well as the vertical distribution of atmospheric ozone up to 3 hPa.
