The dropsonde is one of several weather instruments that measures temperature, pressure, dew point, wind speed and direction inside the hurricane, as well as the surface pressure inside the hurricane's eye.
The capabilities of HALO as a cloud observatory are highlighted through a presentation of the sixth research flight (RF06) of NARVAL2 because in addition to the extensive complement of remote sensing, which was common to all NARVAL flights, it was one of two flights which extensively explored new methods of measuring large-scale vertical velocity using a high density of dropsonde measurements.
Like during a hurricane mission, the Hurricane Hunters fly their uniquely equipped WC-130J Hercules aircraft to release dropsondes periodically throughout the flight, said Maj.
The weather reconnaissance loadmaster collects and records vertical meteorological data using a parachuteborne sensor known as a dropsonde. It measures and encodes weather data down to the ocean surface.

The AVAPS dropsonde system will eject small sensors tied to parachutes that drift down through the storm, measuring winds, temperature and humidity.
The dropsonde is a weather instrument package released by a weather reconnaissance loadmaster into the eyewall and center of the hurricane.
Our last dropsonde measured a central pressure of 919 millibars, which was lower than both Katrina and Andrew.
