Vaisala wins a contract from U.S. National Weather Service

Vaisala has signed a USD 5.8 million contract with the U.S. National Weather
Service (NWS) to deliver Vaisala Sigmet Digital Receiver and Signal Processors,
RVP901. Deliveries will be completed over the coming 12 months. This order is
part of the frame contract which includes the delivery of Vaisala Sigmet Digital
Receivers and Signal Processors as well as the corresponding dual polarization
software licenses. The total value of the frame contract is USD 9.0 million.

The frame contact is related to Service Life Extension Program (SLEP), which the
NWS is undertaking to upgrade their NEXRAD weather radar network. Vaisala has
been working together with the NWS Radar Operations Center in support of
upgrading the existing U.S. weather radar network with modern weather radar
signal processing technology."The NWS is pleased to work with Vaisala in obtaining this technology for our
nation's weather radars, which are a cornerstone of the U.S. weather observing
system that supports our critical mission of providing forecasts and warnings to
build a Weather-Ready Nation," said Dr. Louis Uccellini, Director of the U.S.
National Weather Service."Vaisala is proud of its long-term relationship with NWS. Vaisala has delivered
weather radar signal processors and software as well as other meteorological
products and services, including upper air sounding systems, precision and
global lightning data, and various weather instruments to the NWS over the past
decades. After updating the current radar network with digital receivers and
processors, the NWS will be able to further develop and improve their weather
radar observation capabilities" states Ken Goss, National Sales Manager of
Vaisala Weather Business in North America.

Vaisala weather radar RVP901 signal processing software analyzes the correlation
between the horizontal and vertical polarization information and improve the
detectability of different weather targets. A dual-polarized radar distinguishes
between different types of rainfall; liquid water, snow, sleet, hail and
graupel. Vaisala's weather radar is also able to recognize non-meteorological
objects, such as birds and insects. Utilizing dual polarization technology, the
intensity of precipitation is measured more accurately, providing valuable
information for local short-term weather forecasts in support of building
community resilience to extreme weather events.
