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‑eective. 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.
