dropsonde
A radiosonde dropped by parachute from high-flying aircraft normally over areas devoid of population to measure (and transmit) weather data for all heights continuously during descent.

The GPS dropsonde data were used to compute the depth and strength of the cold pools, that is, the depth and intensity of negative buoyancy similar to that described in Bryan et al.
The aircraft sampling strategy allowed for coherent observations of MCS structure and microphysics using the Doppler radar and microphysics probes and the large-scale atmospheric and ocean environment using the GPS dropsonde and AXBT measurements, which were not available in TOGA COARE.
Collectively the two aircraft provided the most comprehensive suite of observations of combined Doppler radar reflectivity and velocity from the lower to the upper troposphere, microphysical properties, convective cold pools, and air-sea fluxes from the GPS dropsondes and AXBTs in tropical oceanic MCSs to date.
Figure 5 shows an example of the dry air and a strong relative humidity (RH) gradient observed by the GPS dropsondes on 22 November, when the convection moved toward the equatorial region in response to the dry air intrusion from the south.
A GPS dropsonde is a scientific instrument deployed from research and operational aircraft, manned or autonomous, that descends through the atmosphere by a parachute.
