rawinsonde

[′rā·wən‚sänd]
(meteorology)
A method of upper-air observation consisting of an evaluation of the wind speed and direction, temperature, pressure, and relative humidity aloft by means of a balloon-borne radiosonde tracked by a radar or radio direction finder.

PBL depth time series over EOAS-Santiago (at 06 UTC and 18 UTC every date) modelled by WRF model (CTRL line) and different CALMET model resolutions (other lines) and estimated from the available EOAS-Santiago rawinsonde data (dots), only 2006 periods (P2 and P3).
There were several reasons for the relative lack of jets in the remaining rawinsonde profiles.
The largest error reductions were due to the assimilation of satellite radiances, geostationary satellite winds, rawinsondes, and commercial aircraft.
Transport was calculated from wind observations based on rawinsonde data (not interpolated) taken twice daily.
To evaluate the skill of the AERI observations in providing information about the temperature structure in the lowest 1 km of the ABL, the mean bias and root-mean-square error (RMSE) were computed by comparing temperature profiles from Atmospheric Emitted Radiance Interferometer optimal-estimation (AERIoe) retrievals (Turner and Lohnert 2014) with rawinsonde temperature profiles.
Embedding during Exercise Blue Chromite 16, the team successfully deployed two upper air tactical rawinsondes (sensors attached to weather balloons) in advance of a parachute jump, collecting and relaying real-time upper level wind data to jumpmasters.
Types of observations used in the analysis include land surface observations of surface pressure; ocean surface observations of sea level pressure and winds; sea level winds inferred from backscatter returns from space-borne radars; conventional upper-air data from rawinsondes (e.
Four research aircraft supplied by NASA investigated precipitation processes and snow cover, and supplemental rawinsondes and dropsondes were deployed during precipitation events.
satellite-based remote sensing, surface and buoy observations, GPS radio occupation, upper-air observations from rawinsondes and aircraft, scatterometer-based observations, and derived atmospheric motion vectors).
General atmospheric thermodynamic and dynamic structures were provided by rawinsondes launched from Davidstow at 1-2-h intervals during IOPs and a collocated 1290-MHz radar wind profiler.
