Weather balloon Weather balloon A weather or sounding balloon is a balloon (specifically a type of high-altitude balloon) that carries instruments aloft to send back information on atmospheric pressure, temperature, humidity and wind speed by means of a small, expendable measuring device called a radiosonde. To obtain wind data, they can be tracked by radar, radio direction finding, or navigation systems (such as the satellite-based Global Positioning System, GPS). Balloons meant to stay at a constant altitude for long periods of time are known as transosondes. Weather balloons that do not carry an instrument pack are used to determine upper-level winds and
Atelosteogenesis type I include Cardiorespiratory failure is due to pulmonary hypoplasia or tracheobronchial hypoplasia. This condition is evident at birth and may be diagnosed antenatally with ultrasound or magnetic resonance imaging. The infants may be still born. Those that are live born do not survive long. Radiological findings include This includes There is currently no curative treatment for this condition. Supportive management is all that is currently available. This condition was first described by Maroteaux et al. in 1982. Atelosteogenesis type I Atelosteogenesis type I is a rare autosomal dominant condition. This condition is evident at birth and is associated with a very
