The most comprehensive information of a tornado case in the history of China so far was available in this event, including real-time tornado videos, photographs, an intensive radiosonde observation
, radar observations, and intensive surface observations, in addition to independent ground and aerial damage surveys.
gov), close radiosonde observation
to identify the height of the cloud tops.
This first-guess field is adjusted with observed data that includes METARs, SYNOP observations, ship reports, radiosonde observations
, radar data, satellite cloud tracking over oceans, and many more sources.
Comparison of precipitable water derived from ground-based GPS measurements with radiosonde observations
over the Korean Peninsula.
The standard data sets from routine radiosonde observations
at Sendai and Kagoshima show wind velocity profiles at height intervals of several hundred meters (green and light blue), and therefore, were incapable of describing these gravity wave components clearly.
(RAOBs) data are easily accessible  and enormous compilations of quality-assured datasets from around the World are also available for the propagation community .
include the air temperature, pressure, moisture and wind measurements at various levels (up to 35 km).
The accuracy of ZTD obtained from ground meteorological observations using equations (4,5) based on the sensor's precision, forwarded by error propagation is on the level of few centimeters, which has been confirmed by cross validating with radiosonde observations
(Mendes and Langley, 1999).
This linear connection was first determined by Okulov (2003) on the basis of radiosonde observations
at Tallinn Aerological Station (59.
Additional data are provided by nearby radiosonde observations
This is a place where some advance weather knowledge to read radiosonde observations
(RAOBs) can help.
Each country's global model, which provides synoptic information to the mesoscale model through the outer nest's lateral boundary, took advantage of the four daily radiosonde observations
(two additional launches per day) made possible by France's World Meteorological Organization (WMO) station located at New Caledonia, -2000 km east of Lucinda.
