Upper-air Observations Program

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.
