Vaisala's Next Generation Automatic Sounding System Brings Reliable, High-quality Weather Observations to a New Level

Vaisala, the global leader in the environmental and industrial measurements, introduced today the next generation automatic sounding system Vaisala AUTOSONDE® AS41.

Vaisala AUTOSONDE® AS41 is designed to work reliably even in the harshest of conditions also in the remotest of locations. The system allows fully automated sounding operations with low operating costs, remote flexible operation as well as easy installation. Vaisala AUTOSONDE® AS41 is designed for one-month automation at a time, more than doubling the automation time compared to previous systems. The first deliveries of the new systems are estimated to start in Q1/2019.

Vaisala is the leader in automatic upper air soundings, and has delivered automatic sounding systems to its customers for more than 25 years. Vaisala AUTOSONDE® AS41 strengthens Vaisala's global leadership in upper air soundings even further. Currently, eight out of ten leading national meteorological and hydrological services use Vaisala's automatic sounding systems, which enable them to free resources to safety-critical forecasting operations.

Developing Automatic Upper Air Soundings Together with Customers

"With Vaisala AUTOSONDE® AS41, national meteorological services can extend the coverage of their upper-air networks also to hard-to-reach locations. For 25 years, Vaisala AUTOSONDE® systems have shown how well they perform in a wide range of climates," said Jarmo Franssila, Product Manager for the Vaisala sounding systems. "The new AS41system has been tested in two test sites that were purposefully selected from locations providing windy and harsh conditions. More than 1,000 soundings have been performed in these locations to compare and test different design details that relate to reliability of the system in general as well as performance in high wind conditions in particular."

Vaisala AUTOSONDE AS41® is optimized for Vaisala RS41 radiosonde and able to launch 60 radiosondes fully automatically. The new system provides the customers with high-quality and reliable sounding data continuously. The system provides the users with safe working environment, fast and easy loading as well as enhanced remote control system. 60 upper air soundings can be performed with a work effort of half a day. It takes the operator only three minutes to load one radiosonde and weather balloon to the system. The actual sounding and data transmission is fully automatic.
