The Vaisala DigiCOR A® Sounding System MW31 is a sounding receiving station for meteorological and defence applications. It provides meteorological prole data for artillery ballistic preparation and numerical weather prediction models. In addition, the atmospheric prole is useful for e.g. for aviation, CBRN and naval applications.

The Vaisala DigiCOR A System MW31 integrates the control of sounding, archiving of sounding data and the coding of meteorological messages. Automated data handling and a variety of interface options make the message transmission easy in all conditions.

Meteorological parameters are measured by a radiosonde attached to a free ying balloon. Pressure, temperature and humidity are measured by the sensors integrated in the radiosonde. Wind speed and direction is determined by means of GPS navigation satellites, optionally, a radiotheodolite can be connected to the system.

Sounding

Portable and easy to deploy

The MW31 for defence has a rugged laptop and it can be equipped with a portable antenna set designed for eld conditions. The MW31, with its peripheral equipment, is easy to transport, and quick to deploy. Only one person is needed to operate it. The transportation cases are made to carry the MW31, a few radiosondes, balloons and other necessary equipment.

Optional graphical tools

The optional METGRAPH software module provides you with graphical presentation of meteorological data.
