Vaisala provides runway visual range systems for U.S. airports
The U.S. Federal Aviation Administration (FAA) has selected Vaisala's runway visual range systems for use at airports throughout the U.S. The runway visual range system is used by air traffic controllers to provide information to pilots on runway visibility in order to secure safer landings. This is the first system contract Vaisala has made with the FAA. Read the stock exchange release.

Aviation weather systems have been an important part of Vaisala's offering for 30 years
The increasing volume of passengers and air traffic during the past decades has created the demand for more and more accurate and reliable weather data to enable safe operations. The first automated airport weather observing system was delivered to Helsnki-Vantaa Airport in fall 1975. It was one of the first in the world, and thus a source of great pride for both Vaisala and the customer.

Vaisala updates Estonia's hydrological network
Vaisala is updating Estonia's national hydrological monitoring network. The turn-key project ordered by the Estonian Meteorological and Hydrological Institute includes the delivery and installation of hydrological measurement and information systems, as well as training and a one-year service contract to maintain the stations and main centers. The new hydrological network will operate along a countrywide surface weather observation network, recently delivered by Vaisala.

Vaisala's weather stations conquer Mount Everest
The China Meteorological Administration has chosen Vaisala's automatic weather stations for the modernization of the weather observation network in the Tibet Autonomous Region. The contract included over 40 automatic weather stations. Two unmanned stations are based at Mount Everest Base Camp, 5280m above sea level. The Vaisala weather stations will contribute to the understanding of atmospheric and environmental change. They will also provide a useful meteorological service for a variety of users including mountaineers, offering accurate weather data in extreme conditions. Read the press release.

Brazil automates its surface observation network - Vaisala wins a significant order for weather stations
Vaisala signed one of its biggest ever weather station deals with the Brazilian Meteorological Institute. During 2005, Vaisala delivered 145 automatic weather stations to be installed as part of Brazil's automatic synoptic weather observation network. This is a part of an overall modernization program, to which Vaisala has contributed together with the national meteorological institutes of Finland and Brazil.

New Vaisala sensor provides more accurate information on road surface conditions
Vaisala has introduced a new road surface state sensor that measures the road surface conditions in real-time and distinguishes between water, snow, ice, slush and hoarfrost. What makes it unique is that it helps its users to determine the friction coefficient of the road, and therefore identify the prevailing driving conditions. Road salting can also now be better timed, which reduces both costs and the strain on the environment. Read the press release.
