YEAR WHEN RADIOSONDES FIRST TESTED BY VAISALA

Weather observation station

High-quality weather observations under one roof

Vaisala’s sounding systems integrate sounding control, data processing, and output in customized formats. Vaisala’s combination of sounding devices and software are used to process, analyze, archive, and relay sounding data — resulting in optimal networking, detection, and monitoring. Other benefits include:

  • Flexibility and future upgradability of both hardware and software
  • Excellent telemetry link performance and bandwidth efficiency

Our sounding systems are complemented by Vaisala’s radiosondes using sensors to cover all atmospheric and weather conditions in every climate zone including: pressure, temperature, and relative humidity measurement and wind finding. Vaisala Radiosonde RS41 E-models with BioCover and  BioTwine can replace standard RS41 radiosondes in operational use, with the same uncompromising performance and accuracy.

Products and services

Autosonde AS41

The Autosonde AS41 is designed to provide round-the-clock sounding data even in the harshest conditions and most remote locations. Fully automated sounding operations mean there is no need for in-person data collection.
Vaisala Cirrus Sounding System MW51

Cirrus Sounding System MW51

Vaisala Cirrus® Sounding System MW51 enables superior data processing and operational performance over a long lifecycle. Supporting the world-class performance of Vaisala RS41 radiosonde family, makes MW51 an excellent choice for both synoptical and research applications.

MARWIN Sounding System MW32

Vaisala MARWIN Sounding System MW32 provides an atmospheric profile of wind, pressure, temperature, and humidity from the surface up to the altitudes used in the ballistic weather computation. The atmospheric profile is useful in fire weather, aviation, CBRN, and naval applications.
NCAR Dropsonde NRD41

NCAR Dropsonde NRD41

This proven weather reconnaissance device captures atmospheric profiles from aircraft flight level to surface, vastly improving weather observations.

More meteorological data from descending radiosondes

In recent years, national meteorological institutes have expressed more interest in using the descent phase of operational radiosonde soundings. Once a modern radiosonde starts its descent, it continues measurements and can provide another independent atmospheric profile without additional effort.

Success stories

Case

Soundings Data Helps Fight Bush Fires in Australia

To help New South Wales Rural Fire Service know the hyperlocal weather conditions of a fire in order to provide firefighters with accurate forecasts of how the fire will behave and move, they procured a Vaisala sounding system that can be easily moved around the state, wherever a fire breaks out.

Case

Weather-Ready Nation Ambassador

Vaisala is selected as an ambassador to work with NOAA and the National Weather Service in building communities that are ready, responsive and resilient to severe weather events.

Case

Automation of upper-air observations for modernization

Although their sounding stations were established and functional, the Meteorological Service was manually conducting soundings. The organization sought to modernize the weather network with an automated sounding solution that would optimize staff resources, freeing them to focus on other tasks.
