Vaisala Wins WMO Radiosonde Intercomparison
(Thomson Reuters ONE) -
Vaisala Radiosonde RS92 was proven to be the world's top radiosonde as it was
placed number one in the 8th World Meteorological Organization (WMO)
Intercomparison of Radiosonde Systems. The WMO published their final report on
the measurement results on Friday May 13th, 2011 on their website.
The results show that Vaisala's sounding system is the world's best-performing
combination for upper-air in-situ observations, and provides the highest
accuracy of data for a wide range of meteorological applications, such as
numerical weather prediction models, climatology, and synoptic meteorology. The
Vaisala Radiosonde RS92-SGP - operated together with the Vaisala DigiCORA®
Sounding System MW31 - achieved nearly perfect scores in all the measurement
parameters, meeting and even exceeding international observation network
requirements.
The RS92-SGP performed very well in both temperature and humidity measurements,
being highly consistent and maintaining its level of performance also in
demanding conditions. For an example, the RS92 was the only radiosonde in the
Intercomparison that incorporates working protection against evaporative
cooling, an effect that can distort the temperature measurement due to
accumulated water evaporating and cooling the sensor.
The WMO Intercomparison is organized every 4-5 years. It is a continuous four-
week sounding campaign, designed to be an objective venue for assessing the
qualities and performance of different radiosonde systems. The 8th
Intercomparison was held last July in Yangjiang, China. Eleven radiosonde
manufacturers participated, making it the largest measurement campaign in the
history of modern radiosonde intercomparisons.
