Upper-air observations
National meteorological institutes around the world rely on Vaisala systems and instruments for accurate atmospheric measurements. Key measurements include wind speed & direction, cloud height, temperature and humidity up to heights of over 30 kilometers.
Vaisala DigiCORA® Sounding System MW31
The Vaisala DigiCORA® Sounding System MW31 is the new generation of the DigiCORA® Sounding System. It is based on the Sounding Processing Subsystem SPS311, which features new software-defined radio technology.
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.
Vaisala Dropsonde RD93
The Vaisala Dropsonde RD93 is a general-purpose dropsonde for high-altitude deployment from a variety of aircraft. It measures the atmospheric profiles of pressure, temperature, relative humidity and wind from the point of launch to the ground.
Vaisala AVAPS Lite Dropsonde Receiving System
The Vaisala AVAPS Lite Dropsonde Receiving System is a smaller, lighter, one-channel version of the full-scale Vaisala AVAPS system.
Vaisala Tropospheric Wind Profilers
Wind data gathered with Vaisala tropospheric wind profilers can be used to improve numerical weather prediction at the national level and to determine how well a national forecast model is performing.
