Vaisala MW41 Datasheet
DigiCORAâ Sounding System MW41
Features
• Consistent, high‑quality data
• Easy integration to existing
soundings network
• Increased flexibility through
advanced networking options
• Easy and simple operation
• Quick configuration and
modification of station
parameters, also remotely
Vaisala MW41 System supports the world-class performance of Vaisala RS41
radiosonde family. This makes MW41 an excellent choice for both synoptical and
research applications.
Vaisala DigiCORAâ Sounding System
MW41 processes, analyses, archives, and
relays sounding data. The system
consists of a computer that runs Vaisala
MW41 software and is connected to a
sounding processing subsystem via a
network adapter. MW41 software
includes the sounding processing
software running as services on a
computer and an optional remote client
for remote access/use.
Easy to integrate
Upgrading to MW41 from earlier Vaisala
sounding systems is smooth and
cost‑eective. The software is
compatible with commonly used
Windows operating systems and
hardware, making it easy to integrate to
most IT bases and helping to minimize
maintenance costs. Connectivity with
Vaisala Automatic Weather Stations
allows using highly accurate surface
weather information as reference, which
makes operation simpler and less
sensitive to human error.
Flexible to use
As MW41 user interface is separated from
other software functionalities, it can be
operated from anywhere within your
network. This allows, for example,
managing sounding operations remotely,
away from the sounding station.
Additionally, all network users can access
sounding data, remotely.
The standard MW41 software package
includes all features needed to perform
synoptic soundings. For more advanced
sounding needs, like ozone sounding
capability or extended graphics, optional
modules are available. The system can be
tailored for specific needs of a sounding
station.
Intuitive to operate
MW41 follows the radiosonde
preparation process, minimizing the
need for user input and interaction.
When the user needs to act, using the
system is made easier with clear status
indicators and animations, and
a software help is available for additional
assistance. As operating the system is
highly intuitive, training users is faster.
Access to specific functionalities can be
defined by utilizing user groups and their
related privileges.
Quick to configure
Configuring MW41 for operation is easy.
The user interface supports quick
configuration of station parameters,
message creation, and parameter
sending. The system can also be
configured remotely.
MW41 validates sounding data to make
sure it is of high quality. The system can
create WMO messages and special text
reports using the validated data, and the
data is also available in XML format.
