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? Radiosonde
