every 4 weeks

• Safe working environment, gas

lines located outside the

container

• Balloon filling with either

hydrogen or helium

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.
