Technical content
Features
- Upper-air observation system for synoptic and adaptive use
- All benefits of Vaisala Radiosonde RS41 and Vaisala MW41 Sounding System
- Reloading needed only once every 4 weeks
- Safe working environment, gas lines located outside the container
- Balloon filling with either hydrogen or helium
- Remote control and configuration
- Easy loading and stocking
- Controlled access for improved operational safety
- User interface design supports easier system diagnostics High-quality data Complemented by Vaisala Sounding System MW41 and the RS41 radiosonde, Vaisala AUTOSONDE AS41 provides world‑ class sounding data. Its automated and manual operations are based on proven algorithms and procedures, such as the automatic ground check. As a reliable start reference for sounding data, AS41 uses either Vaisala Automatic Weather Station AWS310 installed on a 10‑ meter mast according to WMO requirements or Vaisala Weather Transmitter WXT536 installed on a short mast on the container roof. High data availability Each individual detail in AS41 has been carefully designed and tested to achieve high target rates of successful soundings. AS41 is designed to endure extreme weather conditions around the world. Thoroughly tested automation control and carefully selected components and materials guarantee continuous operation with minimum downtime. Green for operational: AS41 diagnostics is supported by visual cues Cost efficient solution AS41 offers the longest autonomous sounding capacity on the market. Site visits are significantly reduced as reloading is only required once every 4 weeks. As AS41 complies with tight international standards for explosive athmospheres, cost‑ efficient hydrogen can be used as an optional balloon filling gas in place of helium. Easy remote control and monitoring Vaisala Observation Network Manager NM10 is used for remote control and monitoring. Connecting to AS41 through a secure communication protocol, operators can efficiently control sounding schedules, initiate on‑ demand soundings, and perform remote diagnostics. Vaisala Automatic Sounding Station AUTOSONDE AS41 is an upper-air observation system for synoptic and adaptive use. With a loading capacity of 60 radiosondes, it provides the longest autonomous sounding capacity on the market.
