Reliable Weather Information for Beijing Olympics With Vaisala Weather
Observation Equipment

HELSINKI, Finland, March 31, 2008 (PRIME NEWSWIRE) -- Reliable weather
information plays a key role at Beijing Olympics. To provide accurate and
versatile weather information to the organizers and athletes, the Beijing
Meteorological Offices (Aviation Meteorological Office and Civil Meteorological
Bureau) have upgraded their weather observation network in the metropolitan area
with Vaisala equipment. New weather equipment has also been installed at the
main stadium and other venues.

During the past two years, Vaisala has delivered 25 weather stations, 21 road
weather stations, an aviation weather solution, two windprofilers and several
weather transmitters and present weather instruments to the local Beijing
Meteorological Offices. The total value of the deliveries is 3.5 million euros.
The new equipment will continue to serve as part of the metropolitan weather
observation network after the Olympics.

Precise weather information at the venues

Reliable information about current weather conditions as well as on approaching
fronts is essential at the venues. Vaisala's compact weather transmitters are
located at various venues to provide precise, real-time temperature, humidity,
pressure, precipitation and wind data. Additional present weather and visibility
instruments serve athletes and organizers at the tennis center and rowing
stadium. The new automatic weather station at the main Olympic stadium is part
of the regional weather observation network that measures approaching
large-scale weather fronts and transmits the information to the Beijing
Meteorological Offices for forecasting purposes.

Smooth traffic flow prerequisite for successful games

The road network of metropolitan Beijing area has been renewed and upgraded for
the Olympic Games. Vaisala's automatic road weather station network ensures that
the local authorities have real-time information on the weather conditions to
manage the traffic flow.

The new terminal and runway at the Beijing International Airport are ready to
serve the increasing air traffic. Vaisala's aviation weather solution, installed
on the runway, provides versatile weather information to the air traffic
control, pilots and airport maintenance crew. Wind and visibility information
is, for instance, vital to ensure safe take-offs and landings.

games; Sydney, Salt Lake City, Athens and Tourin.
