Vaisala receives its first weather radar orders

Vaisala Oyj Stock exchange release 07 June 2007 at 09:00 Vaisala receives its first weather radar orders Vaisala has received its first weather radar orders. The orders include a total of five dual-polarization radars, which carry Sigmet signal processors and application software. When fully realized, the total value of the radar orders is approximately EUR 4 million. Deliveries will be carried out between November 2007 and June 2008. The Vaisala Weather Radar will be officially introduced to the market by the end of August this year. Vaisala's first weather radar customer is the Estonian Meteorological and Hydrological Institute, which has ordered two dual-polarization radars. One of the radars will be located at the Harku weather station in Tallinn, and the other in Sürgavere in the Viljandimaa province. Both radars will be delivered in November 2007. Another order, for three weather radars, was received from a long-standing Vaisala customer. These radars will be delivered in the beginning of 2008."We are very pleased that our first sales and marketing efforts have resulted in such a successful opening. There is a clear demand for the dual-polarization radar developed by Vaisala, which offers top performance and leading technology", says Vaisala CEO Kjell Forsén. Vaisala's weather radar has been developed in cooperation with leading international research institutions and partners. New technologies have been investigated thoroughly in the R&D process. For example, the radar's dual-polarization technology enables more precise information on the quantity and type of precipitation. Weather radars are mostly used by national meteorological and hydrological institutes. The data produced by weather radars on the intensity and type of precipitation and the movement of rain fronts is utilized for weather forecasts and warnings. The Finnish Meteorological Institute, University of Helsinki and Vaisala have had a prototype of the Vaisala Weather Radar in research and test use from December 2004. The new weather radar complements Vaisala's remote sensing product offering, which currently includes cloud height measurement instruments, lightning detection systems and networks as well as wind profilers.
