Vaisala launches the development of a reference radiosonde for climate change observations

HELSINKI, FINLAND and PHOENIX, AZ, Jan 12 (MARKET
WIRE) --
Vaisala is investing in the development of an operational reference
radiosonde. When complete, this instrument will provide superior-quality
climatological data on the upper parts of the atmosphere, and shed light
on the dynamics of climate change.

"The international scientific community has clearly expressed a need for
a high-precision instrument to enable long-term research on climate
change. As the global leader in environmental measurement, we feel it is
our duty to respond to this need. This development project is a
significant investment towards a better future - we do not expect
commercial gains. Rather, the project is part of Vaisala's Corporate
Responsibility program. We are committed to supporting the research on
climate change and want to provide the best possible tools for
scientists," Kjell Forsen, Vaisala's CEO explains.

Vaisala plans to carry out the project in close cooperation with the
international scientific community. Scientific evaluation has already
begun. After piloting, the instrument will be further developed according
to the experiences gained. The project requires long- term work and
commitment. Vaisala has a history of more than 70 years of experience in
the development of operational radiosondes.

Radiosondes are meteorological devices that are used to measure
temperature, humidity, pressure, wind speed and direction in the upper
atmosphere. A balloon filled with hydrogen or helium gas carries the
radiosonde into the upper atmosphere. The instrument transmits
atmospheric data back to Earth throughout its flight.

Vaisala is a global leader in environmental and industrial measurement.
Building on more than 70 years of experience, Vaisala contributes to a
better quality of life by providing a comprehensive range of innovative
observation and measurement products and services for meteorology,
weather critical operations and controlled environments. Headquartered in
