The National Weather Service (NWS) Upper-air
Observations Program is managed by the Observing Systems Branch (OSB), which is part of
NWS Headquarters located in Silver Spring, Maryland. Upper-air Program staff oversee
the operation of 92 Radiosonde
stations in North America and the Pacific islands. It also supports the operation of
10 stations in the Caribbean. Radiosondes provide upper-air data that are essential
for weather forecasts and research. OSB staff are involved in the development and
implementation of a new radiosonde ground system that will replace the obsolete
systems currently in use. The OSB is also involved in the implementation of new observing
systems such as wind profilers and commercial aircraft observations. What's New?
